Hayate is the main male protagonist 16-year-old butler of the Sanzenin family, and is later the owner. Hayate Ayasaki has had to work to support his parents' bad habits since the age of nine, always moving from job to job, before he was found out to be underage. The experience gained does mean, however, that of all the characters, he possesses the most extensive practical knowledge of how the world operates. Hayate's dad refused to get employed, while his mother is a compulsive gambler, and the whereabouts of Hayate's older brother, Ikusa, are unknown. These events led to their bankruptcy—they abandon Hayate attempt to sell his organs to the Yakuza to ease their financial burdens on Christmas Eve, a debt of 156,804,000 yen. With not many choices left to him, Hayate conspired to kidnap someone to get ransom money. He found a girl, Nagi Sanzenin, and told her that he would kidnap her. However, Nagi mistook his words for his confession of love, so he was later employed as Nagi's new butler. In the beginning of the story, Hayate often mentioned Nello and Patrasche from the novel A Dog of Flanders, and compared his miserable situation to the characters' life. In Kocchi Muite! Miiko Race-Tin, he is a major character appearing in Episode 12, owns Hayate's Muscle Shop and Cafe, driving the Yin-Yang Element.
As a butler, Hayate is capable of all aspects of housework and can even play the violin, but it is his ability in repelling attacks from almost anything (despite his bad luck) that makes him a "combat butler". He once demonstrated a skilled use of fire-arms (capable of wielding an MG3 single-handedly) and is essentially invincible with physical prowess far surpassing any normal human being. At the end of Volume 6, Hayate manages to create an ultimate technique called "Hayate no Gotoku" (like the wind).
In addition to looking poor and seedy, Hayate can also appear to be extremely feminine. He has a girlish face and is good at housework such as cooking and cleaning. This has led to him being forced to wear girls' clothing or cosplay in feminine outfits such as nekomimi, a maid and so on. In episode 36 of the anime, he cosplays as Belldandy from Ah! My Goddess. Later on, this female alter-ego is given a name: Hermione Ayasaki (綾崎 ハーマイオニー Ayasaki Hamaioni). He has been forced to cross-dress at other times.
On the other hand, he often unintentionally embarrasses others by reacting wildly at very simple requests. This may be because of his innocent personality, which often leads him into trouble with other people. In the following episode 7 (Season 2), Hayate and Hinagiku created a spark when they both accidentally touched each other's hands. They both blush, and Hinagiku rushed out of the house to buy some ice cream because she can't face her crush due to embarrassment. It seems that their feelings for each other have increased. He also has a slight interest in Ayumu after Ayumu hugged Hayate on Valentine's Day.
Hayate had a girlfriend named Athena, who was responsible for teaching him cleaning and swordsmanship, as well as for building his strong body. Athena taught him that he must be economically strong if he wants to date with a girl. They had a falling out after his parents pawned an "engagement" ring she gave him. In chapter 239, after being asked by Hinagiku how he feels about Athena, Hayate describes Athena as "Not like the others," and ultimately tells Hinagiku that he is in love with Athena. Following her advice to meet her, he goes to her mansion and confronts Machina, who nearly kills him and steals his King's Jewel before Athena brings him in and treats him. Athena would soon be possessed by King Midas and attack Hayate, Isumi and Sakuya came to help him but they were no match for her, they escaped just in time. Isumi explained to Hayate about Athena's possession and the importance of the King's Jewel. However, Hayate was unable to choose whether to keep the stone for Nagi's inheritance or to destroy it to save Athena. In the end, it was Nagi who made the choice, noticing Hayate's troubles she destroyed the King's Jewel. Hayate was able to beat King Midas and rescue Athena. Both of them quickly embraced each other, after a long time since 10 years ago. Athena told Hayate of what happened after he left, about how a man came to save and free her from The Royal Garden, Hayate immediately recognized the man as his brother Ikusa. After these events, he tells her that she is the one he loves but he comes to deciding he must first protect Nagi. Hayate would go back to Mykonos for one more day of vacation before returning to Japan.
Back in Japan, Hayate had to deal with the problem of Nagi losing the inheritance and thus the mansion. In the end, Hayate met Klaus who showed him an old house, "Violet Mansion". Klaus received the house from Yukariko Sanzenin decades ago and said it was only proper that the house be returned to its rightful owner, Yukariko's daughter, Nagi. Having settled in their new home, Hayate (in Hermione form) met Ruka Suirenji an idol help carried her to where she was scheduled to perform when attacked by a robot control by Yozora Housen, with Ruka still thinking that Hayate is a girl. After that, Athena appeared again in chapter 300, to ask Hayate where his brother was. She told him that she would appear again, and that he should act like they had never met before. She appeared again as a child, with no memories, only that her mission was to find the owner of the Shirosakura, Hinagiku, to help restore her powers. She also stated that Hayate was the one she trusted most. When Hayate takes a bath in Hakuou and unluckily he met Ruka in there. When he wanted to explain to her, Izumi appeared and Ruka collapsed. Ruka then knows Hayate is a boy and left suddenly. When she almost gets hit by a truck, Hayate saves her and apologizes to her for lying to her, and soon Ruka falls in love with him. Recently Hayate, Linn, Tama discovered a mystery room (in chapter 368) partitioned in the storage room. After Isumi disables the barrier, Hayate discovers that the room holds the same coffin he saw in the Royal Garden 10 years ago. Shortly after that Yozora shows up and burns the coffin whilst battling Isumi briefly. He proceeds to intervene when Yozora threatened Athena but was countered effortlessly by her. He later hosts a Welcome Party for the Violet Mansion tenants. Ruka offers to help pay off his debt along with hers before proclaiming her love for him, though Hayate declares he will continue to be Nagi's butler until she a happy grown mistress.
Currently there are a total of 10 people that are in love with Hayate, many of which he has no clue to their true feelings due to his dense nature. They are: Hinagiku, Ayumu, Ruka, Izumi, Isumi, Maria, Nagi, Sakuya, Athena and Kotetsu (Homosexual). However, Hayate has only shown interest in Hinagiku, Ayumu, Maria, Nagi, Athena, and Ruka.
Shun Ayasaki and Mrs. Ayasaki (Hayate's parents) (綾崎 瞬 と ハヤテの母,Ayasaki Shun to Hayate no haha?)
Hayate's parents, who appear only in flashbacks as faceless shadows with the characters "Mother" and "Father" scrawled on their faces. Shun has refused to get employed (on the ground that he is undergoing soul-searching and deserves no less than jobs "most suited to him") and his mother has been a compulsive gambler, which led to their bankruptcy. They abandon Hayate after selling his organs to the Yakuza to ease their financial burdens (a debt of 156,804,000 yen, or approximately US $1.9 million). Later on, Wataru and Hayate find out that Shun was a former member of Wataru's video store which owed Wataru 1,580,000 yen in unpaid late fees. When asked by Sakuya Aizawa if Hayate still has any desire to live with his parents if they had a change of heart, Hayate states that no matter what he does, that would never happen; there are no second chances.
Ikusa is the older brother of Hayate. He has a very kind personality which Hayate likes about him. Hayate met him 10 years prior to when the series began, when he was still a teenage high schooler and Hayate was still a young boy. In a flashback, Ikusa is shown giving a friendly farewell and advice to a lady in a shawl that resembles Yukariko Sanzenin's. Hayate lends him a King's Jewel that Santa Claus (Mikado) give him. Ikusa, in desperate attitude to save a person, turns out to be Athena after she and Hayate had a fight with Ikusa, meeting Athena for the first time. He made a promise to Athena that he will let her see Hayate again. He also appears to host a cross on his forehead nearly identical to the Shiranui's white cross and Linn's forehead cross. It is shown that he is incredibly strong, very good athletic capabilities; it is hinted that his strength may be at the same level as Himegami. Ikusa helps all those that need help and wishes to be reunited with his brother Hayate.
Hayate didn't remembered that he lent a King's Jewel to Ikusa until in chapter 437. Having an encounter with Eight, Hayate finally meets Ikusa (cross-dressing) at a beach who calls himself "lifesaver". He beats up Eight for taking an octopus as of harming sea life, though Shiori reassures him. However, Ikusa doesn't recognize Hayate. As a result, Hayate displays an unusual behavior which scares the others. It is soon discover that Ikusa is actually now a rich owner of the 'Asuki Hotel Resort'. But he refuses to hand over the King's Jewel. After going through such methods to earn the pendant, Hayate realized he had lost sight of himself (desperate to regain Nagi's inheritance, and feeling downfall of Ruka's departure) and reconciles with his brother.
It is later revealed that Suzune is actually Hayate's grandmother. Suzune returns to Hayate as a spirit that Hayate sees while on vacation with his friends at Ayumu's countryside. Suzune recreates an amusement park that Hayate once visited as a child with her. Suzune believed that Nagi was causing Hayate to suffer because of her spoiled attitude and that he only stayed with her because of the debt. Suzune gives Hayate a diamond that would pay off the debt so he could live his own life. Despite this Hayate returns the diamond to her and says that he wants to pay off the debt on his own beside Nagi. Suzune then departs to the afterlife with a smile.
Despite Suzune's slightly violent demeanor, she cares greatly for Hayate. She is very disappointed in her son Shun, for loading such a large debt on Hayate's shoulders. She only wishes for Hayate to be happy and goes to great lengths for him to be so.
The main female protagonist Nagi Sanzenin, 13-year-old, biracial, is the only heir to the Sanzenin fortune. She is short-tempered, spoiled, immature, but kind and cute. She has an otaku-level hobby with manga, anime and video games, and draws her own manga, which is called "Millennium Legend: Magical Destroy" whose main protagonist is a magical girl named Britney (ブリトニー Buritonī). Many of the characters in the anime think that Britney is very ugly and that Nagi's manga sucked. Nagi has a large crush on Hayate, and she thinks that Hayate loves her since they first met. She sometimes tries to make him take an interest in her in many ways, and sometimes, she succeeds. She has successfully kissed Hayate 2 times in total. She gets really jealous when Hayate makes some good statements on other girls, and then punches his face. However, Hayate never understands why Nagi is mad at him (until the final episode of Can't Take My Eyes Off You).
Nagi's only surviving family is her grandfather, whom she greatly dislikes. She regards Maria as an older sister figure, but gets ultimately jealous when Hayate is out with Maria or is alone with her. Nagi's mother, Yukariko, is shown in volume 12 of the manga. She cares for her family and friends, but she doesn't want to show her concern directly, she usually shows her concern with "formal words". Because of her pampered existence, she lacks any worldly knowledge and is even incapable of looking after herself. Nagi is mortally afraid of the dark (due to an incident with Isumi), and so shares her bed with Maria at night. Since going outside is very dangerous because of her status, Nagi favors staying at home, not liking company in general. Hayate managed to convince Nagi that sports is good for her body, and she is able to get into 2nd place on the Hakuō freestyle marathon due to Hayate's absorbing training and her huge amount of love for him.
Nagi is very selfish, but mostly what she likes to do is not so good for her future. She is hard to control; even Maria who has lots of talents can't control her. But Hayate, her average educated and insensitive butler, who saved her from the kidnappers and the mafia, and police chase that occurred from the race that she loses from him, is able to convince her to go to school, do exercise, have many friends, etc. He helps Nagi to be a better person. While Hayate always reminded her to go outside and gather experiences on the outside world, she always thought that will be boring or she will always get lost and risk being kidnapped. Maria always states to her that without Hayate she will always get lost or in danger. Nagi spent most of her younger years living outside Japan. Because of her family's wealth, she became the prime target of criminal organizations. Nagi disliked being a target and spent most of her days indoors playing video games and watching TV and hence slowly becoming a hikikomori. She begins to go to school more often after Hayate transfers to her school. Despite her laziness, Nagi is a highly intelligent student. She skipped grades and is currently in the first year of high school and in the same class as Hayate. Another funny thing about Nagi is that she always forgets the everyday life of an ordinary person.
"Nagi" means "windless" or "calmness", which seems to be the contrast of Hayate, which means "gust of wind" or "squall".
In Shimoda, Nagi decided to take Hayate and Maria on a trip to visit a mysterious meteorite that seems to enhance growth, along with other special powers. Nagi decided to help the alien, Maya, to find its misplaced spaceship. Nagi and Maya find the spaceship at the Saginomiya's place. Nagi accidentally boards on the spaceship, luckily Hayate saves her. When Maya sends Hayate and Nagi home, Hayate encounters Nagi's mother, Yukariko, in a dream and finds out the reason why Nagi comes to Shimoda every year is to remember the anniversary of her mother's death.
On the other hand, in Episode 52, during Golden Week, Nagi, Hayate, and Maria travel to Mykonos Island. Hayate got summoned back to the past when he jumped into the sky to get Nagi's hat back. At that time, Nagi feels uncomfortable going outside, because the mafia is after her. However, Hayate manages to defeat the Sicilian mafia but he made a few holes on Nagi's hat. Nagi doesn't mind and said that the holes are proof that Hayate saved her life. After this incident, Nagi falls for Hayate even more because he has vowed to protect her in the past, present and future. Both Nagis (The one in the present and the one from the past) fall for Hayate deeply. During Hayate's struggle to make a choice whether to destroy the King's Jewel to save Athena, Nagi sensed Hayate's dilemma and decided to destroy the king's jewel out of her own accord so that Hayate could now protect her truly, and not her fortune. She came across Athena on the last day of Golden Week. After coming back from Golden Week trip, Nagi was forced to leave her mansion due to her forfeiting her inheritance after she destroyed the King's Jewel. Later Nagi, Hayate, and Maria stayed at Yukariko's Violet Mansion and started new life.
Nagi trying to sell her doujinshi to the public. Nagi went to show her hard work to Ashibashi-sensei but was shocked to realize her hard work was not good enough. Later, Chiharu tried to cheer her up by taking her to a Doujinshi convention. After making a bet to sell out her doujinshi at the last convention, Nagi gets help from both Chiharu, Hayate, and Kayura in coming out with ideas to create her own doujinshi compare to Ruka her rival. In chapter 328, Hayate invites Ruka over to accompany Nagi in drawing her own doujinshi. After the Comisun event, Nagi decide to make a comeback at the Tokyo Big Sight to where the biggest doujinshi competition will be held there. Believing that having supernatural experiences will help create a concept manuscript for a new manga, Nagi takes an itinerary to Kyoto, but later got lost on the empty streets of Hokkaido until she's found late at night by Dr. Kurosu. Nagi determined to win the competition for Hayate's sake when Ruka confronts her feelings for him. As Nagi's manga, "30 Days of Soul Burning", is being sold and read, she soon realize what she had sincerely desire in her life.
Maria is Nagi's maid and is the one of the only person who understands the relationship between Hayate and Nagi. She appears to be the one in charge of everything in Nagi's manor, since everyone from Klaus (head butler) to the SP either obeys or fears her (or both in some cases). She is highly intelligent, somewhat devious, good at general housework and likes games of all kinds, though she is deathly afraid of cockroaches, which she refers to as "the dark life-form that exists in the kitchen and other places". She has also proved capable of self-defense techniques in times of need. She is, however, poor at disguises, as seen multiple times when she tries to spy on Hayate and Nagi and is recognised instantly.
She has no surname and she doesn't have records of her biological parents. She is found in front of St. Mary's church by Mikado as an orphan, where she got her first name. Not knowing anything about herself, her birthday was decided as December 24, the day she was found. She is the unfortunate one who always has to clean up everyone's messes. She has seen Hayate naked multiple times (and has been seen naked by him once), and she sees the effect he has on other girls, many of whom are attracted to him for his kind nature. Her own feelings for Hayate are very clear, and she blushes whenever Hayate saves her from danger. (Episode 19) Also, when Hayate accidentally tripped on her, they both blush as well. (Episode 22) Although she has chosen to put any feelings for Hayate aside in order to support Nagi's love for him, she has been shown to be curious about love. However, there are countless cases that Maria is unable to control her own feelings for Hayate. One example is that on Valentine's Day, she keeps telling herself that she isn't in love with Hayate, but eventually She ends up making some chocolates for Hayate. However, she smashed it because she is jealous of Hayate's skill at making chocolate. At the end, Hayate ended up making chocolates for both Maria and Nagi. Both girls enjoyed the chocolates.
Maria is also legendary throughout Hakuō Academy for having graduated high school at the age of 13 in just three years while maintaining the position of Student Council President for all three years. Because of this, she was able to recommend Hayate to Hakuō Academy despite him narrowly failing the entrance exams. Due to such unusual experiences, she both appears and acts in a manner more mature than people typical of her age. Because of this, even people near to her speak of her as if she is older than she really is, a pet peeve for her. She commonly responds that she is still a fresh 17-year-old girl and remains 17 years old (according to this phrase) throughout the entire six-month-span of the series. She may have met Athena as a child. After the Golden Week vacation, she was happy about Nagi wanting to have a normal life after Hayate found the Violet Mansion through Klaus. Afterwards, she and Hayate decorated and cleaned it to make it suitable to be lived in.
Mikado Sanzenin is Nagi's grandfather and the head of the Sanzenin family, as well as one of the five directors in charge of Hakuō Academy. He lives in a mansion much bigger than Nagi's mansion with many servants. It is unknown where the Sanzenin fortune comes from but Nagi calls her grandfather an oil tycoon. He has the ability to judge a person's character just by looking at them. From what he saw in Hayate, he gives Hayate a pendant that is supposed to be his compass for life (but turns out to be a cursed pendant).
Even though Mikado is Nagi's only direct relative, they do not get along. This is evidenced when Nagi continuously hits him when Mikado says something that she dislikes. (Episode 11) Nagi dreads going to the main house to visit him. As a result, Mikado is not seen many times after his first appearance, although he makes a brief appearance in volume 12 when Nagi states that although she knows that no matter how much money she has, she cannot bring back her mother; there may still be some people in this world that do not understand this. However, it is obvious that he worries for her, which is shown when he tries to stop the assassination/kidnapping attempts and pushes them onto Hayate when he announces that he will pass the Sanzenin inheritance to the person who makes Nagi cry and beg for forgiveness and which later changed – with the suggestion from Hayate and a little help from Maria – to get rid of the butler first. This further changed in volume 21 of the manga, that the inheritance will be granted to the one who manages to steal or destroy the King's Jewel Mikado gave to Hayate. In episode 51 of the first anime, he hatched a plan to fire Hayate, although it failed to materialize. After Nagi lost the inheritance when she destroyed the King's Jewel for Hayate's sake and Athena, Mikado reveals the best way to have Nagi as his successor again is obtain another King's Jewel.
He is shown to be not very fond of Hayate, mainly because Hayate's dream has nothing to do with gaining big money, or marrying Nagi. He is aware of Nagi's crush on Hayate.
It appears that he was the Santa Claus whom Hayate met ten years ago in chapter 249. "Mikado" means emperor, showing his position in the Sanzenin family.
Yukariko is Nagi's deceased mother. She was Mikado Sanzenin's daughter, and was friends with Mikoto Tachibana and Hatsuho Saginomiya. According to Hatsuho, Yukariko appearance resembles Hayate's. Yukariko appears in Nagi's dream and Hayate's illusion (in 2nd Season). It is also seen in chapter 187, that Yukariko was helped by Hayate Ayasaki's brother, Ikusa Ayasaki. The reason why he helped her is still unknown but the person was definitely Yukariko as her scarf is seen. It is implied that was how she entered the Royal Garden and gained the "Power of Royalty" since she was the "chosen one by God". She often said to Nagi that she would always look after her as the sky and the stars. She died of sickness when Nagi was about 5 years old. According to her character profile, she didn't die because of sickness. Her grave is in Shimoda, and Nagi visits it every year.
Shin is Yukariko's late husband and Nagi's father. He was adopted into the Sanzenin family after marrying Yukariko. Nagi was about too young to remember him. He is also Mikado's son-in-law; he has a similar hairstyle like Hayate's.
In the 3rd season, Shin had served Yukariko as her butler while planning his escape with the Kurotsubaki (Black Camellia), a clock that brings bad luck but can grant the owner a life full of miracles. However, he eventually fell in love with Yukariko and instead wished to be the man worthy of her. He proposed and they ended up getting married, and spent their honeymoon in Shimoda.
After losing his parents at a young age and growing up in a very poor environment, Shin always dreamed of becoming something big. Spending his adolescent days stealing from others, Shin grew into a well-known American thief until he met Yukariko. He died in a car accident in Las Vegas. Mikado reveals that Shin was a con artist who married Yukariko aiming for the Sanzenin fortune, or so he thought. In episode 11, reveals the Black Camellia is a magical sword that exchanges a person's soul, Shin was really inside the Black Camellia for 13 years until Hayate got stabbed, they switch souls, and Nagi finally meets her father (in Hayate's body). Shin wanted back the ring stolen by his former employer Dolly that signifies his and Yukariko's eternal love. At the end of the series, Shin reunites with Yukariko to the afterlife.
Klaus is the 58-year-old head butler of the Sanzenin family, who is usually away on business. He was Yukariko's butler when she was young. He is jealous of Hayate because he does a better job than he does. He had made several plans to fire Hayate, but they all failed, a similarity to Mikado's failing idiotic plans. He saw Hayate crossdress as a catgirl without knowing that Hayate was forced to by Nagi and Maria (episode 8). He is self-centered, has a low alcohol tolerance, doesn't do well with tobacco or women, and likes cars and bikes. Klaus once had a dog named Lucky that used to live in the Sanzenin garden, Lucky appear in chapter 183, chewing Izumi's doll before attempting to attack her, Hayate saves her by hitting him with a large stick. Klaus always gets beat-up by Nagi when he tries to fire or discourage Hayate. In the later series, Klaus swaps places with Hayate to serve the tenants at the Violet mansion.
He is currently in love with Hayate's female character, Hermione Ayasaki.
Akane was Nagi's butler before Hayate. He has yet to make a personal appearance in the manga, but a torn corner of a picture recently discovered (chapter 369) shows Himegami as a child. Judging from the way Nagi and Maria speak of him, he quit due to a problem related to Nagi's personality traits. Neither Nagi nor Maria seem to want to elaborate on his departure. Also with references from the first volume he was close to Nagi. He wrote a book on how a butler can acquire a one-hit kill technique, but later Nagi burnt the book. He is probably around Hayate and Maria's age. In episode 34 of the anime, he makes his appearance, but with his face obscured by the shadows. He returns once more in episode 38 wearing a mask. In episode 39 his face is shown. In chapter 225, Sonia Shaflnarz mentions that were rumors indicating that Akane might have been fired for trying to steal the treasure of the Sanzenin family that is associated with the King's Jewels. In the anime, he also insists that he be called "Princess God" rather than Himegami, which is a direct translation of his surname.
Himegami originally made a brief appearance on the bottom panel at the end of Chapter 146 but was later taken out and replaced with the panel of Hayate and Nagi holding hands.
Tama is a white tiger from Africa, who was rescued by Nagi as a cub, and was raised on Matsuzaka beef and expensive tuna fish, making him incapable of going to the zoo or back to the wild. He can speak the human language, though he does not reveal this to Maria or Nagi because he doesn't want to shatter the girls' dreams. He will lay his life down to protect Nagi, as Nagi saved his life and raised him herself.
Despite the fact he is a white tiger, he was found by Nagi while she was exploring Africa. The manga artist admitted that he made a mistake when fans wrote to him pointing out there are no tigers in Africa. Because of this, when Nagi first finds Tama, she becomes convinced that he is just a cat. Usually when Tama is speaking or involved in a comical situation, he looks rather cartoon-like and, when standing on his hind legs, is about human size. He appears this way in most of his appearances, although he will occasionally be drawn in his actual size and appearance. He has been known to imitate other people's voices, and has done a perfect imitation of Nagi once.
Tama is often seen relaxing or doing human-like activities. However, he seems to enjoy reading male model magazines in his free time, which only goes to show Tama's odd behavior. He once fell in love with a tiger on a picture of a magazine advertisement for Brazil, and tried to machinate a plan involving Klaus' retirement just to get to go see her, before being reminded by Hayate that there are no tigers in Brazil. After Nagi had moved to the Violet mansion she requested that Hayate bring Tama into the new house. Later, Isumi has given him the collar of Nibelungs.
The "White Kitten" Hayate receives from Hinagiku. He is black with a small white X-shaped scar in his forehead. He has a very devilish personality and deliberately gets Tama into trouble. A teary eyed Hinagiku had to say goodbye to Shiranui because her mom had cat allergy. Hayate then decided to take Shiranui and find him a new owner. When Hayate returned to the Sanzenin Mansion, he was immediately welcomed back by Nagi who caught sight of the cat. At first Nagi was doubtful as to taking care of the cat but quickly changed her mind and decided to make the cat a member of the Sanzenin family and named the cat as Shiranui. His name is a reference from the videogame Okami, whose protagonist is also known as Shiranui. Kenjiro Hata apparently was playing this game prior to naming Shiranui.
Shiori Makimura is a genius scientist with the Mikado Hyper Energy (M.H.E) Electronics Corporation as the Chief of Development, Humanoid Nursing and Battlefield Weapons Department, and Advanced Technology Development Division for the Sanzen'in. Her specialties is computers and mechas. Her development team created Nursing Robot Eight and other mechas seen in the series. She is in fact so talented, that she had even built a mecha when she was half asleep. During her high school years she was the vice president of the student council in Hakuou. The president at that time was Maria. She enjoyed calling Maria nicknames like "Little President"; takes growth videos of her, similar to what the Hakuou Three Amiga does to Hinagiku. In volume 3, robot Eight asks her to be his girlfriend and she accepts, but later breaks up. In episode 23, Shiori is sent to teach her old school, Hakuō Academy, because her superiors believe she does not have enough heart. Another weakness Shiori has is that she is often quite forgetful, completely forgetting about building Eight and overlooking the installation of a critical control chip in one of her mechas, which lead to disastrous results.
The secret police with a force of over 2000, they are hired by the Sanzenins to ensure the safety of the mansion's occupants (especially Nagi). They can be easily distracted from their duties sometimes, for example, once they were distracted by a concert while searching for Nagi at Hakuō Academy. Although they will obey Nagi's orders, her authority can be overridden by Maria (who will intervene when Nagi's demands become unrealistic), who can be considered the head of security for the mansion (in addition to being a maid).
Sakuya Aizawa is Nagi's cousin and from Kansai. Like Nagi, Sakuya is very rich and has a similar personality — loud, arrogant, abusive of servants, and unwilling to accept defeat in anything; Nagi is one of the few people who can stand up to her wrath, Sakuya is the one who has known Nagi the longest. Sakuya is the eldest daughter in her family with three younger sisters and one younger brother. Sakuya is obsessed with stand-up comedy, especially Manzai style. She encourages Hayate to become a comedian because she believes that Hayate's life up to now is nothing more than a comedy. She is quite well-endowed for her age, easily surpassing Nagi, Hinagiku, and Isumi, and a match for the normally developed teenagers like Ayumu or Chiharu; so far only Athena and Maria are the ones amongst the "minors" of the cast to clearly surpass her.
Sakuya can often be seen hanging around with Isumi: she is usually present when Isumi performs exorcism, although she doesn't have any special powers. When Isumi disappears after seen in Greece with Nagi, Sakuya flies to Greece to look for her. She's not all bad though, since deep down she does care for her cousin.
Sakuya develops a crush on Hayate in Episode 32 when he saved her from the demon monsters, evidenced by blushing. Her crush on Hayate is further evidenced in Episode 40. However, Hayate doesn't understand Sakuya's feelings for him. On the 5th episode of Season 2, Sakuya falls deeper for Hayate when he tidies up her clothing. However, she can't quite express her emotions, and thinks that Hayate is making fun of her instead. On the 19th episode of Season 2, she expresses her love for Hayate indirectly winking her eye after Hayate made her laugh on the 29th of March. On the 24th episode of Season 2, she expresses her love for Hayate again in another indirect way. He asks Hayate whether or not she can call him "Brother Hayate" instead of "Bankrupt Butler". She did this because her feelings for Hayate has grown.
On the other hand, Sakuya also develops a crush on Wataru in Episode 51. Her heart was touched when Wataru thanked her for giving him a spot in Hakuou. She also stuck herself close to Wataru on the 23rd episode of Season 2 when she thinks he did a good job on the gag show for the audience, as a sign of love for him. However, Wataru doesn't want her to stick that close, and pushed her away. Wataru then fell on top of Sakuya, making the both of them blush. Their feelings for each other has increased after that.
She rarely appears again, but during the Golden Week vacation, she, with Wataru and Saki, went to America. As Mikoto's bet against Wataru, Sakuya was dressed as a bunny girl and was subjected to strip if Saki lost in her gambling match against Mikoto. After battle with Wataru and his mother, she asks for Mikado's private jet to find Isumi in Mykonos Island, because she was lost. Then they appeared when Hayate was attacked by King Midas for the first time, she helped much in the final battle, and bring back everyone to Japan. Sakuya and Isumi are worried about Nagi's inheritance. But Isumi said that Nagi does not get help from her and Sakuya. Then Sakuya came to the Violet Mansion to see Nagi then she met Chiharu in there and keep her secret as a maid. She wants to understand Nagi's manga, but she can't. Then she helped Wataru for lending some money for his new businesses.
Gilbert Kent is Sakuya's illegitimate half-brother. He does not look Japanese because of his brown curly hair and dark complexion, but Sakuya thinks they look "alike". After Nagi's grandfather announced a condition to inherit the Sanzenin fortune, Gilbert quickly begins to pursue the fortune, even begging for it. However, Hayate easily stops him from hurting Nagi and getting the inheritance. He later receives a mecha from Shiori Makimura, whom he refers to as a mad scientist, to help him in his pursuit.
Gilbert again tried to gain the inheritance during Hayate and the other's trip to Mykonos. He confronted Hayate and Nagi but was immediately beaten up and ignored. He finally asked for a handicap to make his chances better. His conditions for the fight was to play a 2v2 beach volleyball game, and if he won the King's Jewel will be destroyed. Choosing Hinagiku as Hayate's partner. Everything was going well for him because at that time Hinagiku intentionally held back in playing since she wanted to act weak in front of Hayate. However he made a mistake when he insulted her flat chest. The insults were enough to make Hinagiku serious, and with 1 hit of the volleyball destroyed Gilbert's partner. And with the final play of the game, Gilbert and his last robot were defeated.
Mr. Aizawa (咲夜の父,Sakuya no chichi?, Sakuya's father)
Mr. Aizawa is Sakuya's father. A man with a strange sense of humor, he is apparently proud of his "naked conversation skills", much to his children's horror. Despite this, he gets along very well with his younger children.
Mrs. Aizawa (咲夜の母,Sakuya no haha?, Sakuya's mother)
Sakuya's mother and Nagi's aunt. She is also the cousin of Yukariko who has yet to appear in the series, but she is mentioned in episode 23 (season 2) by Sakuya.
Makita and Kunieda are Sakuya's personal butlers. They don't appear unless they're told to do a task. Both butlers wear glasses and dark navy suits. Makita and Kunieda are very skillful, as they can complete tasks instantly and perfectly, even amazing Hayate with their skills. In the anime, it is revealed that Makita plays the guitar and Kunieda likes to read books. Makita is 35 years old. Kunieda is 34 years old.
Saginomiya Isumi is a girl who always wears a kimono and, sometimes, a stole. She is Nagi's best friend; they met at a party a long time ago. When all the other children, Sakuya included, laughed at Nagi's first attempt at writing her own manga, Isumi took interest in it and asked Nagi how it ends. Nagi then asked Isumi (in a childish sense) to marry her. As a result, Nagi has always asked Isumi for ideas for her own manga, but it proved that Isumi's ideas were even more awful than that of Nagi's.
Like Nagi, Isumi is very rich; however, Isumi is soft-spoken, kind, and a good cook. While she does not have an awful sense of direction, she constantly gets lost because she is apt to forget her destination and believes herself to be reliable and independent (a belief further enforced by the flighty nature of her mother and grandmother); the fact that she can disappear from people's eyes instantaneously only complicates the matter, without a guide, map and compass prepared 2 hours in advance she will get lost and then says the other people got lost. She also has a habit of saying, when she doesn't understand how to use a machine such as a cellular phone or a vending machine, that the machine is broken. She displays a high level of empathy for Nagi's feelings, yet she does not recognize Wataru's love for her, a fact that Nagi, Maria, and Hayate comment on. She has, however, seemed to have developed a crush on Hayate.
Although what Isumi actually did on Episode 24 was to decurse Hayate's pendant, she did confess to Hayate afterwards. Hayate, as always, misunderstands it as something else. In volume 5 of the manga, it is revealed that she can perform exorcisms. Humorously, she calls this power "hand soap", though Hayate assumes she means "hand power". She loves Hayate and does not wish to see him sad.
Isumi is the inheritor of the secret mystical power called Jutsushiki Hachiyo, the spell of the eight leaves. This power is only inherited by a chosen female child in the Saginomiya family. In volume 11, she loses this power, which causes some slight distress to Hayate as he would have to literally bleed through grueling trouble in order for her to regain it, but she rejects his help, saying that she does not wish to cause other people harm for her own ends. However, in volume 12, when Hayate is on the verge of tears thinking of a way to save Nagi from being blasted off into outer space, she kisses Hayate on the cheek (while he is bleeding profusely after being struck on the head by Ginka) and regains her power, sending Hayate speeding towards the UFO to save Nagi.
Later in the story, Isumi has a prominent role regarding the events about Athena and Hayate's past, by aiding Hayate in several ways during the fight against King Midas. It is also revealed that her hair temporarily pales whenever she overuses her power.
Hatsuho is Isumi's mother. She is 31 years old. She forgets things extremely quickly, much to Isumi's chagrin. Like her daughter, she knows a lot about the spiritual realm and supernatural things. However she is hopeless when it comes to technological gadgets. She also has connections in the past with Yukariko. According to her, Hayate looks like Nagi's mother, Yukariko.
Ginka is Isumi's great-grandmother. She is 91 years old. She demonstrates a high capacity for fighting, as shown in volume 11, when she tries to defeat Hayate. However, this was all done because she was worried about her great-granddaughter, whom she cares very much for. Ginka normally looks like a young child, but this is only because she is able to stay healthy and alive by sucking on the blood of people who are close to death (driven to their critical limit).
An army of butlers’ as skilled swordsman serves the Saginomiya family. Hayate mistook them as assassins upon his first meeting with Isumi. They are overprotective for Isumi’s safety due to her zero sense of direction.
Wataru Tachibana is Nagi's fiancé, but they have no feelings for each other. Wataru claims that his parents arranged their future marriage entirely for money. He lives and runs a video-rental store in the city, the last store owned by the Tachibana group, which lost all their assets and is on the verge of bankruptcy due to the recession. His dream is to make his store great and acquire a fortune greater than Nagi's. Wataru is in love with Isumi. He initially hates Hayate for accidentally stealing Isumi's affection, but later he looks up to him and strives to be like him. Despite this, he still calls Hayate by his own personal nickname for him, "Butler In Debt" or "Bankrupt Butler" (or a variation thereof), and doesn't hide his usual irritation. He's same age as Nagi, Isumi & Sakuya.
Later on in the manga, it is revealed in an off-hand conversation that Wataru's store is actually starting to do well and is making some profit. However, he has yet to retain a fortune that can match Nagi's. On Golden Week, Wataru took Saki on a trip to Las Vegas. They had a gamble with Mikoto to reach a decision since she started looking down on Wataru and his dad for their lack of business insight. Sakuya also ended up being part of the bet since they did not have enough money. Sakuya was dressed as a bunny girl and forced to strip if Saki lost in the gamble. They ended up winning by asking Hayate if he would choose red or black and choosing the opposite in the roulette. Wataru later receive a pendant (King's Jewel), from his mother, that is similar to Hayate's and Aika's. It is also shown that he cares for Saki, although in a different way from how he feels about Isumi. This is implied through the great means he often goes through to make her happy, or to otherwise make up for wronging her. This includes a time where he believes she is downtrodden because he had forgotten her 20th birthday, when he had also promised to buy her a furisode (a long-sleeved kimono used for coming-of-age ceremonies). In order to make up for this, he goes as far as to buy a 200,000 yen (roughly $1,650) yukata for her because the furisode was too expensive, and even rejects a chance (as he sees it) to win Isumi's heart. Later on, he realizes his love for Saki when he saw her face in his mind just before confessing to Isumi in chapter 330. After they deposit the money received Sakuya to a bank, Wataru decided to quit from Hakuou to manage his businesses. Then starts anew so his video shop "Doujinshi. Game. Comic. V. Tachibana" will profitable enough.
Enkyō's daughter and Wataru's mother. She lives in Las Vegas with Jirousaburou, and has amazing business insight, claiming to be able to net 1 billion yen in 2 years from the land appreciation of Wataru's store. She considers both Wataru and her husband to have very poor vision in what relates to business. According to Nagi, she went senseless after her dearest friend Yukariko passed away, thus relying on gambling for a living.
Saki Kijima is Wataru's maid. She is 20-years old. She is significantly older than Wataru and lives with him in his video-rental store. Her biggest fear is that Wataru will start watching child movie when he reaches 90, which he agrees. She takes on a mixture of a servant and elder sister role to Wataru, often changing from being subservient to scolding him, depending on the situation. She also reacts strongly whenever Hayate touches her anywhere, such as tapping her on the shoulder or carrying her away from danger, worrying about whether or not their physical contact will affect her chances of getting a husband later in life. This is not only limited to Hayate, but other men as well.
Saki came in contact with the Tachibana family when Wataru's grandfather, Enkyō Tachibana, saved her and her grandmother, the legendary maid Rei Kijima, while they were traveling around the world searching for her missing parents (who, in fact, are not lost at all and live in Ueno).
Saki develops a crush on Wataru on Episode 25 by stating that Wataru has grown into an old guy. Further evidence proving this is on Episode 29, when Wataru holds her hand, both blushing.
Rei Kijima is Saki's grandmother and the legendary maid. She set off on a journey with Saki to find her missing daughter and son-in-law. While on the journey, she protected presidents from assassination, solved unsolved mysteries that would have been filed away forever, and liberated oppressed citizens by serving cuisine to emperors. When she was 62 years old, she was about to die in the middle of the Sahara Desert when Enkyō Tachibana saved her with his strong words. In order to repay the debt, she travels with Enkyō fighting crime.
Hinagiku Katsura is the current Student Council President, and kendo club president at Hakuō Academy. She is 15 (currently 16) and is an expert with swords, specifically kendo. Her family is also quite wealthy like most of the other girls at Hakuou. She can also speak as many as 17 languages, and is an expert linguist. She first meets Hayate when he is lost on the huge Hakuō campus and ends up rescuing her. She had been helping a baby bird who had fallen out of its nest, but due to her fear of heights, had become stuck without her realizing it. Hayate ends up helping her down the tree, and then promises that he will help her should she ever call for him. In gratitude, she invites him to the top of the school's clock tower, where only student council elites are allowed. She allows Hayate to call her by her first name and also seems to be infatuated by Hayate and his attractive personality.
However, in volumes 9 and 10, it is revealed that Hinagiku suffers from a past nearly identical to that of Hayate's – she, along with her sister, had also been abandoned by their biological parents, who left them with a debt of 80 million yen (approximately 1 million US dollars) shortly before Hinagiku's sixth birthday. Following this, her sister, Yukiji, managed to pay off the debt (albeit through what the manga depicts as rather dubious means) and the two of them went to live with the Katsura family, as Mr. Katsura had been Yukiji's elementary school teacher. The hair clip Hinagiku is always seen wearing was a birthday present from her real parents. When Hinagiku finally sees the beautiful view from atop the clocktower on the night of her 16th birthday with Hayate's help, though, she finally realizes that she actually loves him. She had been afraid of admitting this to herself because she was scared that she would forget about her past if she fell in love with him. She likens her feelings to the scenery atop the clocktower: she had been unable to see them because she had been too scared to. When Hayate asks her if she's still scared, she replies that while she is, it's not a bad feeling, which is a possible response to both her fear of heights as well as her fear of abandonment. Hinagiku's problems are not over yet, however; in Volume 8, when Ayumu and Hayate were staying over at Hinagiku's house, she promised Ayumu that she would support her in her relationship with Hayate. Now, having fallen in love with Hayate herself, she must come to terms with her feelings of betrayal as she tries to find a way to tell Ayumu about her feelings. Although Nagi seems convinced otherwise, Hayate himself doesn't seem to think that Hinagiku could have feelings for him, which leads him to say things that hurt her as well. Later on in the series, after many interruptions, Hinagiku manages to confess her love for Hayate to Ayumu in order for her to help clear her conscience. Upon hearing the news, Ayumu cheers up Hinagiku, leaving her confused. She explains that although her feelings may not be returned, she is content to be with Hayate nonetheless and encourages Hinagiku to try her best, provoking a competition between the two friends.
Hinagiku is sometimes referred to as being rather masculine for a girl by other characters in the series. This is exemplified on Valentine's Day in volume 7, where Hinagiku is given a lot of chocolates by female admirers. Miki suggests this is because Hinagiku is seen as being "cooler" than the boys, and the fact that she was rather domineering at a younger age. This is similar to how Hayate is seen as being rather feminine. In addition, on Valentine's Day, she had considered giving Hayate chocolates as well, but ate it herself because she didn't want to add to Hayate's troubles after Ayumu had already given him chocolates as a way of confessing her feelings to him a second time. Thus, on White Day in volume 12, she regrets not having given him any chocolates, as he would feel no obligation to return the favor as a friend.
When Hinagiku tries to confess her love to Hayate, he surprises her with his feelings, telling her that the one he loves is none other than Athena and that he needs to confess his feelings to Athena. Hinagiku advises Hayate to pursue his feelings and not be hesitant. She met Athena prior to meeting Hayate a year before. When she goes back to the mansion she's staying at, Hinagiku breaks down in tears, whilst trying to accept the fact that Hayate loves someone else. In later chapters we see that Hinagiku has decided to help Hayate and the others when King Midas made his move and attacked the hotel where the others were staying. She goes to Athena's mansion to help Hayate defeat King Midas and rescue Athena. Once Hayate and Athena are reunited (while displaying great signs of affection for each other), Hinagiku leaves in tears trying to give them some privacy. The next day, after the Athena conflict is resolved, she learns from him that Athena turned him down, but Hayate escapes before she is given a chance to pursue the topic. In Chapter 300 and 301 Athena (Alice) while in her child form calls Hinagiku her "Mama" and Hayate her "Papa" causing the two to be greatly embarrassed as those present make jokes on the misunderstanding. She eventually goes to live with Hayate in the Violet Mansion after Athena threatens to tell Hayate about Hinagiku's feelings for him.
It is interesting to note that Hinagiku is the most popular character in Hayate no Gotoku. She has won numerous anime/manga popularity contests on the internet, the most significant of which is by winning first place in the 2009 International Saimoe League (the most prestigious and the most popular female-moe anime online poll).
Yukiji is the 28-year-old sister of Hinagiku. She is a world history teacher at Hakuō Academy and doubles as a 24-hour gate guard. She refuses to let Hayate enter the school when they first meet because she is afraid that letting unauthorized personnel on campus will result in a salary deduction for her. Her attitude softens after Hayate first saves her from falling off the clock tower, but she still almost causes Hayate to be rejected from Hakuō by unnecessarily making him anxious during his entrance exam. She repays Hayate by telling everyone in her class on Hayate's first day that he is a super cool person. She has a group of underachieving students (Izumi, Miki, and Risa) who hang out with her a lot. She lives on the Hakuō campus; she tells Hayate that she does this so that she can save rent money and use that money to buy alcohol instead. It is a recurring gag that she will do anything for money, going as far as to allow an evil spirit to possess her because it told her it would give her a million yen. When Shiori Makimura is sent to teach at Hakuō, Yukiji is demoted to sub-homeroom teacher. She later regains her position as homeroom teacher when Makimura is promoted to a higher position. It is implied that Yukiji was once Ayumu's tutor who taught her how to play the guitar and later gave Ayumu her guitar.
In the extras of volume four of the manga, the author writes that before starting the Hayate no Gotoku! manga, he had created a one-shot manga where the story is about a female high-school student and her little sister trying to pay back an 80 million Yen debt, then writes that these characters are, in fact, Yukiji and Hinagiku.
Mrs. Katsura (雪路とヒナギクの養母,Hinagiku to Yukiji no yōbo?, Yukiji & Hinagiku's adoptive mother)
The adoptive mother of Yukiji and Hinagiku, she seems to have a fondness for Hinagiku. She is also attracted to Hayate due to his feminine looks, and tends to always want to make him to wear Hinagiku's unwanted clothes, much to her embarrassment.
Mr. Katsura (雪路とヒナギクの養父,Yukiji to Hinagiku no yōfu?, Yukiji & Hinagiku's adoptive father)
Ayumu Nishizawa is a girl from Hayate's previous school before he became a butler and is usually seen with Hinagiku. She is currently 16-years old. She always had feelings for Hayate and is happy when he pays his old school a visit. It is revealed in Episode 10 of Season 2 that she fell in love with Hayate because he saved her from a bicycle crash. She violently lashes out at anyone who badmouths her and Hayate, including a teacher who called Hayate a dropout because his parents had refunded all his school fees the day Hayate was sold. She confesses her feelings to Hayate, but Hayate rejects them after getting a vision of Nagi. Undeterred, she tries to talk to Hayate when she sees him a week later, but she runs into Nagi. She is shocked that, in terms of metaphoric strength, Nagi is a dragon while she is a hamster. Nishizawa retreats, vowing next time to bring a stronger hamster. She later challenges Nagi to karaoke, only to lose. In the anime, it is a running gag that she appears in every episode, usually for less than 30 seconds, doing something entirely unrelated to the episode's plot, though always related to food. However, she who has successfully confessed her love towards Hayate, which often places her in situations where she is alone with him. Ayumu is friends with Wataru, from whom she often rents videos, and tested her chocolate on him before giving it to Hayate on Valentines Day. Another weird habit about her is that every time she buys a drink at the vending machine that responds with "Thank you very much", she would always say, "You are welcome". Currently, Ayumu also works part-time at Wataru's new video shop.
On May 15th, she believes Hayate has forgotten her birthday but in actual fact he and Nagi were planning a surprise party at the cafe the 3 worked at. She tries to get him to realise its her birthday and him trying to keep the fact that he knows to a secret. Ayumu loses and leaves straight after her shift, Nagi convinces her to come back and she is greeted by Nagi, Hayate, Hinagiku and everyone else. While visiting the Violet Mansion, much to her dismay she learns that Ruka has become newest tenant. After seeing that Hinagiku is happy with her moving in and still seeing Ruka as a threat, Ayumu decides to rent out the last room in the Violet Mansion.
Kazuki Nishizawa is the younger brother of Ayumu and a friend of Wataru. Like Hayate, he has a feminine appearance. A year ago, Kazuki met Nagi crying in front of a cherry blossom tree and fell in love with her at first sight. He is also same age as Nagi. When he met her again in Wataru's store, he invited her to a walk and finally confessed his love to her. During their "date" she told him that she already loves someone else; and after he saw Hayate saving Nagi from falling in a lake, Kazuki realized it was Hayate she loves. But the date did not end on a low note because Nagi had finally come to remember her first meeting with Kazuki. He buys a manga that Nagi was handing out at a doujinshi convention (in chapter 293), technically Kazuki volunteer to help increase Wataru's marketing.
Izumi Segawa is the student representative for Hayate's class at Hakuō Academy. She is the younger fraternal twin sister of Kotetsu Segawa. Her family owns the game company - SAMY (a parody of SONY). She met Hayate when they were younger (volume 17 flashback) as she was getting attacked by a dog and gave him a kiss for saving her, as well as telling him she would be his bride when they're older; although she mentioned nothing about that incident when she first met Hayate at Hakuō Academy, possibly due to both parties not remembering each other. Like her friends, she addresses Hayate as "Hayata". Izumi gets along well with Hayate, and is comfortable enough to even change clothes while he is in the same room (though not for him to actually watch her change). Later on, she realises to have feelings for Hayate; it is confirmed when he gives her 17th birthday cake. She calls herself as member "Red" of the Hakuou Three Amiga, and she mostly the protagonist among the group.
Kotetsu Segawa is the combat butler of the Segawa family and the older fraternal twin brother of Izumi Segawa. As a running gag, his hobby is his extreme love of trains and train turntables. It seems that he has terrible luck with women that left him feeling bitter about the entire female gender, but while he is at Hinagiku's birthday party, he runs into Hayate and immediately falls in love with him, or rather his alter-ego Hermione. He soon learns of Hayate's identity from Izumi. Angered by this, he kidnaps Nagi in order to bring Hayate out. After Nagi confronts him on his shallow attitude towards love in general, he vows to change his attitude and still loves Hayate even after discovering that he is male. He seems extremely hung up on Hayate and uses various methods to try to spend time with him. Kotetsu is the only person whom Hayate really hates (besides his parents).
Stringer is Izumi and Kotetsu's father. He is very protective of Izumi, particularly against males, to the point that Izumi must smuggle Hayate in as a girl, though the truth is later revealed. He does not appear to care much for Kotetsu, betting his life against Hayate's in order to gain Izumi's hand in marriage.
Risa Asakaze is the head of the disciplinary committee for Hayate's class at Hakuō Academy. She is often seen hanging around her friends Miki and Izumi. She speaks in a rather boyish manner and likes to cause trouble for fun, which is ironic since she is the head of the disciplinary committee. Her family lives in a giant Shinto shrine. She calls herself as member "Black" of the Hakuou Three Amiga.
Fumi is a first-year student of Hakuou who is first seen when she leaves for Hakuou, and is usually seen alongside her close friend Sharna Alamgir. She often makes hilarious remarks about other people, usually high ability in mathematics, and is very gullible as well. She addresses Hinagiku as "visible panties person" when she first arrives and encounters Hinagiku standing on the branch of a tree rescuing a stranded cat, the same way Hayate did, and comments that she can see Hinagiku's panties. She later appears (in chapter 306) where she was reunited with her big dog, Armageddon, with the help of Athena and Hayate after it stumbled into the Violet mansion. In the manga, Fumi expresses her wish to become the next president of the student council. According to the author, she is going to be the next future student council president of Hakuou, succeeding Hinagiku.
Armageddon is Fumi's dog, who usually goes around town to find free food. One day, he ended up at the Violet Mansion where he finds Alice (Athena) holding his favorite treat: a chocolate cornet. Later on, Armageddon grabbed Wataru’s briefcase with 100 million yen then losses it to some bandits. Tama translates Armageddon where the money went; instead this escalates into an argument between the two animals. Fumi explains that the reason why he loves Alice is likely because her hair "drills" resemble chocolate cornets.
Athena is an heir of the Tennousu family and is revealed to be one of the five directors in charge of Hakuou Academy in the manga. She has mainly appeared in the manga. She has only been shown in the anime during a brief flashback where Hayate reflects on his first girlfriend. Her parents are presumed missing or dead, since she lived alone. She is Hayate's ex-girlfriend, as well as his first Mistress, whom he met 10 years ago. Since he was very young at that time, he called her "A-tan" (アーたん Ā-tan) for short. He lived with her for a while at her castle "Royal Garden". There she taught Hayate how to do house chores such as cleaning and cooking. She even taught him sword fighting. She also healed Hayate's body and reinforced it with some kind of spell, which could be the reason for Hayate's power.
Both of them cared deeply for each other, to the point in which they decided to spend their life together. That decision was taken after Hayate worked really hard to get a present for Athena. He was able to get her a ring. However, the ring was designed to fit a grown up woman. Despite that, the simple fact Hayate did that much for her made Athena really happy. Right after he gave her that ring, she told him that engagement rings came in pairs, and so she took a ring from one of her pockets and gave it to Hayate, saying both of them would wear those rings when they grow up. After this event, Hayate was able to convince Athena to live with him and his parents, and once so he decided to finally confront his parents and tell them about this. At the beginning, it seemed things were heading into a positive direction, but his parents betrayed him once again, by pawning the ring he had received from Athena, which he had entrusted them.
By the time Hayate had returned to the Royal Garden, to pick Athena up, she had already seen the things Hayate and his parents had. Athena told Hayate not to see his parents again, telling them they were the worst kind of people. Hayate, not understanding why Athena was behaving this way. After a short, but heated discussion, Hayate told Athena she wouldn't be able to understand him, because she didn't have any parents. Before he was even able to take his words back, Athena attacked him. During their battle, Hayate was able to notice giant spectra with the shape of a skeleton with horns on its skull. Apparently, Athena was completely unaware of its presence and unable to see it. However, it is later revealed that the skeleton is a personal summon. Once the battle was over, Athena told Hayate he could leave, and, saddened due to their fight, Hayate left. Immediately afterwards, Athena tried to call him back, but it was too late, for Hayate was no longer there. Then, saddened because of Hayate's departure, she broke into tears, realizing she had ended up alone once again.
After leaving the Royal Garden, Hayate began wandering in the streets aimlessly, as he was still deeply saddened because of his fight with Athena. Eventually and surprisingly, he met his older brother, Ikusa, who told him to apologize. Hayate, following his brother's advice, tried to return to apologize, but he could no longer reach the Royal Garden. At the end of volume 17, it was revealed that Nagi's grandfather, Mikado Sanzen'in, bought the land where the Royal Garden existed and built Hakuō Academy over it.
Athena and Hayate still dream about these events, even after 10 years. While Hayate expresses his longing to see Athena again. She referred to the dream as "extremely detestable", but then in her thoughts she said: "Even though I've cried my tears dry that day, you still appear in my dreams..." Athena's earliest appearance is (in chapter 88) when Hayate explains the reason he doesn't deserve to be a girlfriend to Hinagiku and the others. She then appears (in chapter 144) when Hayate remembers her after saying that he's not good with girls; in chapter 172, when Hayate cries about her when Izumi asks him what his first girlfriend was like; in chapters 178–187, when Hayate meets her as a child.
In chapter 233 of the manga, Hayate finally meets Athena after 10 years. Much to his surprise, she shows no signs of remembering him and kicks him out. Afterwards, she is shown calling out his name in private while blushing, revealing that she lied to him. Later, it is also revealed that she is also friends with Hinagiku, but didn't talk to her for a while because Hinagiku also gave her the nickname "A-tan". In chapter 239, Hayate admits to Hinagiku (who was just about to confess to him) that he is in love with Athena.
After Hayate's fight with Machina she was the one who treated him and brought him into the mansion. Later, Hayate manages to confront Athena. A fight ensues, where a skeleton hand attacks Hayate from A-tan's back wherein later Isumi arrives to aid Hayate and confirms that the skeleton hand is an honored spirit possessing Athena because of a deal. Hayate was left to decide to destroy the King's Jewel and save Athena, but Nagi will lose the Sanzenin inheritance or protect it and ensure Nagi's safety, and let A-tan and the spirit unite. That honored spirit which possessed Athena is King Midas. In the latest chapter, it is revealed that Athena is still in love with Hayate, but regrets that events of the past made them part ways. After Nagi crushes the King's Jewel herself and entrusts Hayate in protecting her in the future, Hayate determines and manages to rescue Athena from King Midas, which was apparently destroyed. After King Midas is destroyed, Athena originally intends to stay with Hayate, however she soon realizes that he cannot give up Nagi and so decides to part ways with him again (although on friendly terms this time). Before she leaves, she declares her love for Hayate and he does the same and apologizes for what he had said to Athena 10 years ago, thereby by settling their argument from the past. She later meets Nagi returning her hat but at the same time telling her that next time she will not return it (she is referring to Hayate) and gives her the empty ring box that Hayate got her, she is seen wearing the ring. In chapter 266, it was stated that Athena and Machina are going to go to Japan. Athena has since made a re-appearance in chapter 300 (both as the current and younger Athena). Athena then hands Hayate a ring (the one he gave her 10 years ago) then asks him to become her butler convincing him that she really is Athena. The nature of her return has not yet been revealed, but is hinted to be related to the Royal Garden and recovering Athena's lost memories and power. The key to regain it back was to stay with Hinagiku for at least 3 months (due to possessing the Shirosakura) at the Violet Mansion.
When the deadline draws near, Athena states that she will temporarily regain her original form thanks to a simplifying power on the grounds of Himegami's land - Violet Mansion. Athena proceed to recover Ikusa's memory as he expresses thankfully to him for his past actions.
Athena's butler. To date, he has only appeared in the manga. He appears to be slow on the uptake and is frequently called an idiot by his mistress, much to his chagrin. He loves hamburgers, but despite his small frame he was strong enough to lay a near fatal blow onto Hayate. He had also stated that he is not human, Machina seems to have the ability of superhuman strength just like Hayate does, he also has a hidden skill to transform himself into a giant serpent (which is his true form) with a jewel in its forehead. Machina gives Hinagiku the long white sword, Shirosakura to help Hayate save Athena. After the Golden Week arc, Machina is found at Sakuya's mansion (in chapter 408), and she feeds him food endlessly.
Nagi's childhood friend and Jenny's older sister. Hisui is an unseen character, and an exclusive candidate for the Sanzenin inheritance. She is Mikado's niece. Mikado fears Hisui and she would succeed as his successor if Nagi doesn't. It is shown in after the Doujinshi arc, she has Yozora as her loyal servant, spying on available candidates, such as Hayate, Ruka, Nagi. Hisui and her maid Yozora were planning to use Ruka as a candidate to gain access to royal garden because Hisui intends to obtain the King's Jewel, and she may also have intel on Athena Tennousu.
Jenny is the younger sister of Hisui, and a friend of Nagi's; she appears in a flashback accompanying Nagi in Africa where they find Tama. Despite being four-years-old in the flashback, Jenny looks nothing like her age and carries a lighter in the shape of a rifle. She also claims to have ninja skills.
Yozora first appeared in chapter 285, after secretly launching a bottle rocket attack at Hayate as he attempted to transport Tama to the new apartment-house residence, Violet Mansion. She attempted to rent a room there, but was rejected by Nagi due to her flirtatious ways with Hayate. When a photo of an old man is found in the Violet Mansion, she is given the mission to retrieve it, going so far as to conjure (apparently via magic) a couple of robots, culminating with her crashing Ruka's concert in order to retrieve said photo. She continues to spy on the Violet Mansion that Nagi and residents live in, and when Hayate, Linn and Tama discover the coffin from the Royal Garden in a formerly secret room of the building, Yozora attacks and is engaged by Isumi. Yozora's powers are strong enough to withstand Isumi's incredible powers. In Chapter 433, reveals that Yozora serves as a maid to Hisui.
Chiharu Harukaze is the Secretary of the Student Council, known for her cold and serious personality. However, she seems to share Nagi's interest in anime and video games, but only shows this side of her to Nagi and Hayate. Secretly, she works as Sakuya's maid; she uses the alias Haru, when her father's company goes bankrupt, but nobody in the Hakuō Academy is aware of this, with the exception of Aika Kasumi. Chiharu may have a serious, hardworking nature. Currently she stays at the Violet Mansion as a tenant when her house caught fire while her parents were practicing making Motsunabe. And as a result has gotten close to Nagi due to the similar hobbies they have. Chiharu invited her to a doujinshi convention with hopes of restoring Nagi's "burning spirit". She introduced Nagi to the Author of the doujinshi "Flying Dolphin" that she helped sell, Ruka Suirenji. Ever since then, she has been helping Nagi to write and publish her own manga, going around with her to come up with ideas for it.
Miki Hanabishi is a member of the student council and the vice-representative for Hayate's class at Hakuō Academy. She specializes in investigation work, which may be the result of being the daughter of an important government official. She has a mischievous nature, especially when it involves Hayate or Hinagiku, and suspects Hinagiku's feelings for Hayate. Like Nagi, she dislikes exercising. Her friends Izumi and Risa are often seen with her. She calls herself as member "Blue" of the Hakuou Three Amiga.
Aika Kasumi is the Vice President of the Student Council. Like many other Hakuō Academy students, she comes from a rich family. While she may be seen as a sweet, kind, and gentle girl to most people, secretly she is also very manipulative and takes advantage of any situation she sees, a fact that only Hinagiku and Chiharu are aware of.
Despite this, she does care about her friends and would never betray them. For example, when she learned that Chiharu was secretly working as a maid for Sakuya, she hid this secret from everyone despite the fact that she wrote it in down in her weakness notebook in order to remember it. She also has a pendant (King's Jewel) similar to Hayate's and Wataru's. She later appears in Myoknos, and gave advise to Hayate about Hinagiku and suggest him to have dinner with her in chapter 224. It is revealed later that she had some relationship with Athena. She also appears to have a fiancé.
Kotaro Azumamiya is the master of Kaede Nonohara and a member of the kendo club. He is 16-years old, same age as Hayate. He is considered the weakest member of the club because his strikes are random and dangerous. He has a vulgar mouth, which obligates Kaede to scold him accordingly in his duty to refine his master into a gentleman. When he is in trouble, he calls for Kaede to fight for him and, with exception to Hayate, always picks fights with those with the highest possibility of being weaker than he is. Out of jealousy, he challenges Hayate to a duel when he sees him being friendly with Hinagiku. He is often beaten up mercilessly by Kaede for his weaknesses. Recently, he has lost his self-esteem ever since Kaede went to study abroad in England. When going to Mt. Takao, he tried to recruit Hayate so he reminds him of Kaede's words of complimentary. He is the only character introduced so far whose endurance is worse than Nagi's. Recently, it has been shown that various members of his family are manga artists, and that he himself works as an assistant for Gouji Ashibashi.
He has a crush on Hinagiku (Episode 16, 27) and is jealous of Hayate simply because he called her "Hinagiku" instead of "Ms. Katsura".
Himuro Saeki is the 17-year old combat butler of the Ookouchi family. He is usually seen smelling a single rose or reading a book while his master throws rose petals behind him. Himuro loves money more than anything in the world, but he does not try to gain the Sanzen'in inheritance because he already has his master's money. Himuro robs Hayate of his necktie in their first meeting so Hayate gives him the nickname "necktie man" in the manga. In the anime, this nickname is changed to "Prince Necktie".
Like Klaus, he throws roses like daggers. He can also create a rose whip and can use a powerful move that involves striking the opponent with rose petals. He is very agile and is able to stand on the side of trees. Unfortunately, he has a glaring weakness against money. In fact, Klaus "defeats" him by offering him a large sum of money, and he strangely begins to bleed profusely as if struck immediately after. His ultimate attack has yet to be revealed. Despite being greedy, he does care for the well being of his master.
Taiga is Himuro's master, but it is difficult to tell which one is the master and which one is the butler. Taiga follows Himuro around throwing rose petals creating a rose storm. He can be mistaken for a little girl at first due to his voice and appearance. Taiga's hairstyle changed in the anime. He does not have a short ponytail in the manga but gets one in later chapters. He is 10-years old.
He has a crush on Himuro, evidencing that he is homosexual.
Kyonosuke Kaoru is a gym teacher at Hakuō Academy. He is usually seen building Gundam models in the staff room or during lunch, and adores fancy cars. He spends all his money buying Gundam models and even borrows money from Yukiji to buy more. He is 28 years old but he is still single and without a girlfriend. In episode 29 of the anime, it is revealed that Kyonosuke has feelings for Yukiji, whom he has known from childhood. During the Golden Week vacation, he and Yukiji went to Italy. While staying there, Kyonosuke confesses to Yukiji.
Kirika Kuzuha is the Superintendent of Hakuō Academy who first appears asking Yukiji to tell Hayate that he had failed the entrance exam. In the anime, she possesses a power level three times that of an ordinary person, but the moment she uses all her energy, she drops to the floor until she consumes a lot of sweets. She tends to do extreme things to kill her boredom, going as far as to put sharks in the school pool and changing the school trip to the Amazon. Thus, she is an enemy to the students and the student council. She's also bisexual, having a fierce and romantic relationship with her female butler Shion, and being attracted to both Hayate and Hinagiku. This is due to both being good looking and cute, and the former's femininity and the latter's masculinity.
In the anime, Kirika and Shion are manipulated by a Jörmungandr in Season 1 as guardians of the Amazon treasure (ancient butler robe) for unknown years. Hayate, with his newfound power, managed to defeat the Jörmungandr once and for all in episode 39.
Shion, whose name is "poem" and "sound" in kanji, is a devoted butler of Kirika Kuzuha. She first faced Hayate after Kirika loses her energy while attacking him. She's also one of the reasons why Hayate joined the Butler Battle Tournament. She has an amazing aura, so much so that she can create her own "territory" (reminiscent of certain characters in Yu Yu Hakusho/Poltergeist Report). However, if her shoes are knocked off, she reverts to her real middle school child form, which is powerless. She pampers the superintendent with sweets and makes sure that she is always contented and happy. She also seems to be a bit bisexual herself. Despite this, She is romantically attached to her master. She does however seem to share the same sexual interest in girls and boys. (Having made Hayate feint with a seductive blow to his ear and blushing wildly at Hinagiku's tough nature.)
Kaede Nonohara is the 18-year old combat butler of the Azumamiya family. He appears to have white hair and an almost always smiling face. His eyes are always closed and he is very polite. He encourages his master to be a gentleman and to be manly enough to fight his own battles even if he were to lose.
In contrast with his gentle and polite exterior, Kaede is very brutal, senselessly beating his master when he acts like a weakling. In combat, whenever Kotaro asks for his help, he does the opposite, either throwing him into the battle zone or beating the boy up.
Kaede is very quick and is able to do a Tatsumaki Senpuukyaku-like (hurricane kick) attack. His ultimate attack is the "Safety Shutter: Grand Explosion Immolating Dark Murder!", which is a fire attack released from the edge of his sword in the shape of a dragon that engulfs the opponent in flames. Kaede's only weakness is seeing his master getting hit by his own ultimate attack. Despite his ultimate attack being strong, he was defeated by Hayate in episode 19.
Currently Kaede has graduated and left for England to continue his butler studies.
Souya is one of Hayate and Ayumu's friends who attends Hayate's previous high school, Shiomi. According to Ayumu, he's really (and only) good at swimming. During the Mykonos trip, while exploring the underground water tunnel with Nagi, Ayumu mentions that she learned a lot from a book on swimming that Souya lent her. In chapter 75, Souya and his friends from Shiomi run into Hayate, after catching up with him at a restaurant they unwittingly leave Hayate with their bill for 50,000 yen. Later, Souya visits the Sanzenin Mansion to repay Hayate for their restaurant bill. He is aware of Ayumu's crush on Hayate. In chapter 443, Souya reappears to stand for Hayate to reconnect with his older brother. He is also the protagonist of Hata Kenjirou's previous work, Heroes of the Sea Lifesavers.
Natsumi is one of Hayate and Ayumu's friends who attends Hayate's previous high school, Shiomi. She is Souya's childhood friend. She's good at cooking but bad at swimming. Natsumi can't swim for 10 years since she nearly drowned while she was on a boat with Souya at the sea. Later, while thinking about her future Ayumu notices Natsumi announcing to the Shiomi swim club that she'll become a lifeguard but she'd have to be able to swim 10 meters (chapter 359).
Sonia Shaflnarz comes from a family part of the Sicilian mafia. She is born in Mykonos Island, Greece. Her surname suggests that she is Italian. She met Hayate at the train, to the point of saving him from a muscular debt ridden anime fan. In the English version, she speaks in an Italian accent. She moves to Japan in order to get revenge against the Sanzenin family, because her father died due to the family, though not directly. In "Extra- Radical dreamers" of chapter 41, her father hid in a trash can to assassinate Nagi on Mykonos island, but Hayate prevented it and defeated him. After that, he quit the mafia and went to Japan to become a cook. He then died because he didn't know that there was poison in blowfish. Sonia impersonates Sister Fortesia, a sister from the Church of Alexander Mark and the Tiger's Pit for Butlers for the purpose of approaching Hayate and the Sanzenin family, with a M.H.E robot in control. She speaks fluent Japanese, but she uses harsh words and blames it on the fact that she does not know Japanese very well. Sonia has unbelievable strength and fighting ability, and uses tonfas as weapons.
In volume 8, it is revealed that she has some feelings for Wataru, going to his DVD rental store and growing extremely jealous when she sees him expressing concern over Saki. However, when Saki is kidnapped, she uses the situation to get Wataru to kiss her on the cheek in exchange for Saki's rescue. By the time Hayate (who was on the scene at the time of Saki's kidnap) reaches the kidnappers on his bike, he finds that the kidnappers are already tied up, their car impaled by a telephone pole in the shape of a cross, and Saki looking confused and unhurt on the side.
Sonia is also one of the people trying to get the Sanzenin fortune. During Hayate's and the other's trip to Mykonos, Sonia attempted to steal the King's Jewel from Hayate. It seemed that she was either in collaboration with Gilbert Kent or she simply used him. Sonia attacked Hayate with the use of seduction. During their fight, Ayumu was nearby causing Hayate to panic if she misunderstood the situation. Taking advantage of the opportunity Sonia took the pendant and ran to her home but Ayumu who earlier met Sonia was told where her home was located. Ayumu and Hayate arrived in her home and Hayate told Sonia to give up. However Sonia refused and threatened to destroy the stone so that no one will get the inheritance. Sonia originally wanted the stone to use the inheritance to make her chances of ending up with Wataru better. So when Ayumu reasoned with Sonia that the one she fell in love with was not the type to notice someone because of money, she finally gave up and returned the King's Jewel to Hayate.
Linn Regiostar is the priest of the Church of Alexander Mark who died and became a ghost. He is apparently an RPG and dungeon crawler fanatic as he became a spirit because he died from a poison arrow trap in a dungeon he built underneath the church using all the church's donations. He has a cross shaped scar on his forehead similar to Shiranui and Ikusa Ayasaki. At first he was spiritually bound to the dungeon, but after it was destroyed, he appears in the outside world and now moved to Nagi's mansion, where he follows and haunts Hayate. Unfortunately for Hayate, only people who have been in the dungeon before can see him. Despite being a father he is perverted, and is fond of Maria. However, he does appear in front of Hinagiku in volume 9, trying to guide her confused feelings towards Hayate, although the conclusion that she reaches is not the one that he was expecting.
His pervert actions like making Isumi dressed as a maid, peeking under the skirt of a female model, and possessed Sakuya and saying some dirty words. He is currently residing in one of the rooms in Nagi's apartment building, which he filled up with his anime and manga collection (which Hayate stated he would destroy). Linn sensed a suspicious aura within the Violet Mansion, later reveal to be a secret room that holds the coffin that Hayate saw in the Royal Garden.
It should be noted that Viz has translated the priest's name as "Rean Radiostar." Before he died, he seemed particularly fond of the Ultima and Dragon Quest series, even to the point of calling himself Akiba's "Lord British".
The gakukangumi are represented by three katana-wielding Yakuza men in suits. One of them sometimes carries a chihuahua around. They are first seen taking Hayate away to harvest his organs, presumely attempting to kill him in the process, until a mysterious hero called "Mask the Money" (actually Nagi in disguise) stops them and buys Hayate's debt off them. Later, they run into Hayate after he saved Isumi and tell him that they actually like him despite their shady relationship with him. They then get into a fight with Isumi's bodyguards, which then evolves into a free-for-all after Hayate tries to leave without helping them. In the anime, they are referred to as the "nice men" or "very kind people".
In the manga, Kashiwagi the guy with the scar cross his eye, makes re-appearance in chapter 269 as Hayate attempts to find a house for 20 million yen when Nagi forfeit her inheritance.

Jouji appears again (in chapter 155) when Saki was concern about Wataru's feelings.
Eight is an orange robot in love with his creator. He was created to be the ultimate nursing robot by the Sanzen'in Technology Division. He is waterproof and equipped with "nursing missiles" and rocket boosters. Eight's downfall is his quick temper. He snaps after being called "ugly" and seeks revenge after he is defeated. Through his dialogue, he reveals that he only desires revenge in order to prove himself to the one he loves: his creator. Sadly, Shiori has a habit of being totally dismissive of him, going as far as telling him she made a "mistake" in putting him in line for incineration when he actually needed to be trashed in a more appropriate category. Nonetheless, he eventually gets a reprieve after his latest upgrade, when he becomes Shiori's boyfriend after finally confessing to her.
Eight receives an upgrade before each appearance. He is upgraded to v8.1 after his first defeat, upgraded to v8.2 before meeting Hayate in the amusement park, v8.3 after he becomes a couple with Shiori, and upgrades his form after Shiori is transferred to Hakuou Academy. In the anime, Eight upgrades himself to v8.1 after he steals the control chip from Nursing Robot Nine and upgrades to 8.2 as his second form, but he is reverted back to v8.1 after he is beaten by Yukiji and Hayate.
Prototype Seven is a mecha created by Shiori Makimura for Gilbert Kent. It has Eight's version 8.1 operating system and data installed, the most violent version of Eight. Prototype Seven is supposedly controlled by the control chip, but it was left out by mistake because it was being built when Shiori was falling asleep. As a result, Gilbert loses control and it violently searches for Nagi and Hayate. Hayate finally destroys it using an HK MG3.
Thirteen is the mecha-butler who serves Nagi while Hayate learns to take the school's term-examination.

He makes Nagi and Maria happier than Hayate does, but eventually, Nagi chooses Hayate rather than Thirteen.

Voice of the Heavens is the narrator of the series. Throughout both the anime and the manga, he narrates on what happens in the series while at the same time mocking and ridiculing the characters about what they are doing, with frequent snarks at the absurd plot and the silly nature of the story. Some of the cast can hear him and respond accordingly. He appeared in episode 50 of the anime as a tall man, Teruo Mikiri, with no face hosting a quiz game. In the third and fourth season, Hayate and the heroine characters mostly does the narrating.
Orumuzuto Nadja appears mostly on the first page of each volume of the manga. She claims to be a goddess. She exists outside the world of Hayate no Gotoku, greeting the reader, making comments on the manga, and conducting character interviews. She acts like a TV host and carries around a microphone. Nagi does not get along with her. Nadja makes one appearance in the manga in chapter 9, appearing on TV with her eyes censored and voiced changed. Nadja's only appearance in the anime is in episode 7 as a lifeless doll. On every character CD except for Saki and Wataru's, she conducts an interview.

His curse was unleashed by Sakuya who was messing around his cursed work and sadly end up on Hayate (who had the worst luck in this anime & manga) and the only way to break his curse was to go to the nearest tallest place and destroy during a duel. His first appearance in the anime was after Nagi's kidnapped and Hayate fell off a hill (and strange enough, changed from a cat maid to a bunny girl costume) his first impression was being perverted and was slaped senseless by Hayate for the curse.

The second main female protagonist Ruka Suirenji is Chiharu's friend. She first met Chiharu when she praised one of Ruka's doujinshis. Later, she is helped by Hayate (in Hermione form) and it is revealed that she is a singer (in chapter 297); later on she is found out to be a full blown idol. Ruka was raised for 16 years to be an artist to fulfill her parents’ ambition and make it on a grand scale. However, they went broke by investing in her and finally left her along with the debt of 150,281,000 yen on Christmas Eve similar to Hayate. Ruka makes her formal appearance in chapter 280, when Chiharu tells Hayate a few things of her life resemble his.
She appeared at the final day of Golden Week when Chiharu and Nagi attended a doujinshi convention. Ruka is then seen where Hayate was fighting a robot summoned by Yozora. In the chaos, she was injured. When Hayate attempted to bring her to a hospital, she refused, and thanked him for being concerned for her. Hayate convinced her to trust him and agreed to carry her to her destination, passing the cosplay grounds where she mistakenly assumed Hayate is a girl. Ruka revealed to Hayate that she is in fact an idol. She gave him a backstage pass and asked him to follow her to the changing room. Her manager Atsumari (集?) burst in and asked who Hayate was. Ruka responded by saying that she is her relative, who is helping out for the day. Later, Ruka appeared in front of a large audience, including Nagi and Chiharu. Nagi thought Ruka was like a goddess upon first seeing her on stage. Then, Yozora's robot appeared and had gone berserk. Due to this, Hayate was then forced to get rid of it. Ruka did a spectacular back flip before singing one last song and she successfully drew the audiences' attention back to her. However, Ruka fainted right after leaving the stage because of her injuries and stunts in the concert then woke up in a hospital.
Ruka re-appears when suddenly she comes to visit Chiharu and to her surprise, she finds Hermione (Hayate). Ruka decides to repay Hayate for saving her. Therefore, Hayate asks for a song as he thinks her voice is beautiful which they go to a karaoke. That night, Ruka returned to the Violet Mansion after her work. To their surprise, Ruka arrives then befriends Nagi and afterwards. After learning Hayate’s true name, (which she finds as a commanding good name even if she believes he is a girl) Ruka tells Hayate that if he was a guy she would have already fallen in love with him then embraces him; he also realize that Ruka really honest and naïve. Hayate hesitates to reveal his truth gender to her but Hinagiku claims that he has to confess sooner or later.
One day at her apartment, Ruka collapsed from being overworked and saved by Hayate. Atsumari suggests that a health manager be brought in for Ruka's sake. Ruka asks Hayate to be her health manager, and he agrees to care of her from now on. One morning, Ruka decides to thank Hayate by catching up to him. However, she caught Hayate wearing a butler uniform which leaves her confused. She decided to go to the Hakuou to personally ask Hayate if he indeed is a guy or just a girl that loves cross-dressing, suggested by Maria. She arrives at Hakuou clock tower, along the way, she bump into Izumi who is covered in ink and gets her all dirty and goes to the bath so they could clean themselves. Much to her surprise, Hayate is also in the bath and this flustered Hayate for Ruka still doesn't know that he is a boy. Afterwards, Ruka takes off the towel covering her body. Hayate realizes that he couldn't continue lying to her anymore. Ruka finally finds out Hayate is a boy (in chapter 326) and becomes embarrassed then leaves. Hayate later saved her from getting hit by a truck and promised to grant one of her wishes one day as an apology even if its costs his life, she forgive and agrees to trust him once more with a smile.
Hayate asks Ruka if she could help Nagi with her manga since both of them are manga authors. Nagi realized that they have more in common, she and Ruka work together to draw a doujinshi that can sell over 1000 copies. After the Comisun event, Ruka soon becomes more focus on manga rather than working as an idol and left her apartment then moved into the Violet Mansion when Atsumari bans her from doing more drawing. Hayate learns about Ruka's debt which Atsumari reveals after discovering Hayate's not Ruka's relative. Later, Hayate receives a phone call from Atsumari, who warns him that Ruka is suffering from Gastritis due to all the stress she’d been through, Hayate asks Ruka about her health and said she been coughing up blood for the past 2-3 days. Isumi takes Hayate and Ruka to the Rainbow Village to where they can relax. In chapter 382, when the two were alone in the cabin cause of a sudden downpour, Ruka listens to Hayate's story why he became a butler, then she reflects on her feelings for him and kisses him!
