Oz, heir to the Vessalius Duke House, has just turned fifteen. His life is rich and carefree, darkened only by the constant absence of his father. At his coming-of-age ceremony, everything changes when the clock that was silent for 100 years rings out during the ceremony. For no reason that he can discern, Oz is cast into the prison known as the "Abyss", only to be saved by a girl known as Alice, the Bloodstained Black Rabbit, B-Rabbit for short( a chain ). When he and Alice got out of the Abyss, it shall now change his life. The mystery there begins as Oz unravels the mystery behind Alice, the Abyss and the strange organization known as "Pandora".
- Chains (チェイン Chein )
- Beings from the Abyss that were at one point human, transformed by the Will of the Abyss. They must sign a contract with a human contractor in order to leave the Abyss. Chains involved in illegal contracts must repeatedly consume humans in order to gain power. Some chains, such as Humpty Dumpty, can have multiple contracts. When they do, for each contract it makes, the revolution on an illegal contractor seal will slow down even more.
- Contract (契約 Keiyaku )
- An agreement between a chain and a contractor. The chain is bound within the contractor and can be called out at will. In return, the contractor provides passage for the chain out of the Abyss. Legal contracts, that were made possible by Pandora, granted the ability never to age the Contractor. In illegal contracts, a clock-like seal appears somewhere on the Contractor's body, over their heart. Each time the chain's powers are drawn, the hand in the seal moves like on a clock. If a contract between the chain and contractor becomes void it will kill the contractor. Once the hand makes one full rotation, both the contractor and the chain are dragged into the deepest level of the Abyss.
- Contractor (契約者 Keiyakusha )
- A human who makes a contract with a chain. There are certain procedures to making a contract, but imprompt contracts can also be made, although they are illegal.
- Abyss (アヴィス Avisu )
- The world that chains come from. It exists in a different dimension as the world, and as thus, time doesn't truly exist in the Abyss. A person can find themselves in any random time period upon exiting the Abyss, though usually the person is transported forward in time. According to Break, the Abyss can appear as a prison or a broken toy box, depending on the person.
- Intention of the Abyss (アヴィスの意志 Avisu no Ishi )
- The existence that governs the Abyss. Usually appears in the form of a bloodied rabbit doll with big round eyes. The real form of the Will of the Abyss is similar to Alice but with white hair and wears white or light colored dresses whereas Alice wears dark colored ones. Apparently the Intention of the Abyss wants Oz to go back in the Abyss, and is revealed to be Alice's twin. The Intention of Abyss and Alice were both conceived in the human world and born in the Abyss by Lacie. The Intention of the Abyss hates Alice and wishes to destroy her. It is revealed her real name is Alice as well and that the name Intention of the Abyss was only a title given to her by Revis as his experiment. She is Lacie's daughter who remained in the Abyss and became the human vessel for the Core of the Abyss.
- The Four Great Dukedoms (四大公爵家 Yondai Koushaku Ke )
- It currently consists of the Vessalius, Rainsworth, Nightray and Barma family. These four Dukedoms have been in existence before the Tragedy of Sabrie. They founded the Pandora and each hold chains and a door to the Abyss. Of these four houses, the Vessalius and Nightray houses are thought of as exact opposites, like light and dark: the Vessalius house works publicly, while the Nightray house is responsible for doing the behind-the-scenes work.
- Before the Tragedy of Sabrie occurred, the Vessalius family was a third class noble family, and thus, not part of the Four Dukedoms. Instead, the fourth Dukedom was the Baskerville house - with Glen as the head. When Jack killed Glen for starting the Tragedy of Sabrie, the Vessalius family was seen as heroes. And thus, the Vessalius substitutes the Baskervilles as the fourth Dukedom. Therefore, the Baskervilles holds the fifth Door to the Abyss.
- Pandora (パンドラ Pandora )
- An organization founded by the Four Dukedoms. It specializes in research regarding the Abyss.
- Tragedy of Sablier (サブリエの悲劇 Saburie no Higeki )
- The city of Sablier was once the capital city of the world. However, 100 years ago, for unknown reasons, someone used a ritual to send the entire city, with its citizens, into the Abyss.
- Children of Misfortune (禍罪の子 Maga Tsumi no Ko )
- The Children of Misfortune is a myth which has been ongoing for hundreds of years. The myth is telling that children born with red eyes will bring terrible misfortune, such as death and destruction, which in this case actually happens. Known Children of Misfortune in the series are: Lacie Baskerville (killed trafficmen and danced in their blood), Vincent Nightray (killed the whole royal family to save his brother) and Xerxes Break (his entire Master's family was slaughtered except for the daughter and to save them he killed over 116 people and offered them to his Chain, Albus, hoping that the Intention of the Abyss might be thankful and change the past).
- Doors are gates to the Abyss that the Four Dukedoms control. Each Dukedom has control over one, with Baskerville holding the last, fifth Door. It is revealed in Chapter 41 that all along, the door of the Baskerville's was hidden in Sablier, which is under Pandora's control. Yet, Pandora has never thought to look within to find it.
- Blood sealing mirrors
- An item used to make a legal contract. Instead of the contractor drinking the blood of the chain, the blood gets absorbed into the mirror where a seal is formed, keeping the seal off of the person. If the mirror is broken, you can lose the contract to the chain. It also has a limit on the power you can use.
Vessalius Dukedom 
- Oz Vessalius (オズ＝ベザリウス Ozu Bezariusu )
- The main character of the story, Oz is a 15-year-old boy with blond hair and green eyes and is from the prestigious Vessalius family, whose father, Zai, is the reigning lord. His mother was killed by the Nightray family, but despite this, he retains a bright, optimistic, and energetic personality. The story of Pandora Hearts starts when Oz turns fifteen. During the ceremony to celebrate this reaching of adulthood, he was dragged into the Abyss for the 'sin of his existence'. There he meets a young girl named Alice who turns out to be a Chain. Oz makes a contract with her in order to escape the Abyss. Upon returning to the real world, he finds out that 10 years have passed. In order to find out what his sin meant, he began to work under Break as part of Pandora. During this, it is shown that when he was young, he worked hard to gain praise and recognition from his father. However, he had discovered that his father hated him to the point of not wanting to touch him. After experiencing this, Oz began to think that there is no guaranteed thing in the world. He thought of himself as weak and, in order to protect people, he should at least remain an obedient child and let harm come his way. After traveling into the Cheshire Cat's lair, Oz meets Jack Vessalius and in turn becomes his 'medium'. Jack eventually speaks at Pandora's headquarters and the public hail Oz as a 'hero'. Oz finds that he can swap control of his body with Jack if he calls hard enough and may sometimes even see snippets of Jack's memories. According to himself he is quite skilled with the sword, particularly in self defense. However, he has very little real experience in fighting. Oz likes cute, younger girls and flirts with them frequently. He once wished to marry Sharon when they first met. Oz, himself, thinks of Alice as his precious someone, calling her his "sun". He believes that Alice is the reason that he can still smile.
- Jack tells Oz that he has the "right" or "prerequisite" over Alice's powers and that a seal won't restrain Alice's powers any longer, giving Oz the ability to use B-Rabbit's power, even without Alice's permission or Gil's help. Oz proves it when he was able to stop Alice's B-Rabbit's power temporarily on his own; another time when Oz was almost kidnapped by the Baskervilles at Latowidge, and then recently when he was able to summon B-Rabbit's scythe to fluently fight his assailants inside Sablier's illusion, despite the fact he had never used a scythe before. According to Lotti, Oz was supposed to be the vessel for the sake of hiding the existence of Jack Vessalius and should the vessel be broken, Jack’s existence will be brought to light and the further warping of abyss’s will, who seeks for him, will most probably interfere with the real world. Later, Oz reunites with Gilbert and immediately meets with the person behind Oz's homicidal nature: Zai Vessalius , his father. It has been seen in chapter 45 that Oz has had a will to destroy everything until Alice stops him. In chapter 46, however, according to Break, Oz may not be the real Oz Vessalius , as during his birth, Oz's father suddenly took him away and perhaps did something to him or changed him for another baby. In chapter 70, it is revealed that his body was Jack's all along, while Oz is actually the real B-rabbit. Being the B-rabbit, created by the Will of the Abyss at Jack's demand, he has the power to break the chains that keeps the world from falling in the abyss.
- Oz is voiced by Junko Minagawa.
- Alice (アリス Arisu )
- The heroine of the story with a height of 150 cm. Alice first appears as a chain that persuades Oz to form a contract with her in the Abyss. In fact, she is actually the infamous B-Rabbit (Blood-stained Black Rabbit), the most powerful chain in the Abyss. Alice's goal is to find her lost memories, which plays a major role in the story. In human form, Alice has long dark brown hair with two side plaits. She has a huge appetite and loves meat especially. She is hotheaded and loud-spoken and says what she thinks without regard to the consequences. Despite this, she has a soft side, especially when Oz is involved. She hates when Oz leaves her alone, but to hide it she usually says, "I'm in a contract with you. You are my manservant, and as a manservant, what were you thinking, leaving me behind!?" or she just hits Oz and says, "Shut up".
- It also appears that she is developing feelings for Oz, being that she considers his health when using her powers. In chapter 41, she bites his cheeks to make him feel better, copying a picture Sharon showed her thinking it was biting instead of a kiss. Also, in episode 20, she tells Sharon, who threatens her to tell her what she has on her mind, that she felt left out and ignored when Oz went to talk with Break without her and when he was happy to see his sister. Also, in chapter 60, Alice senses Oz is upset. Thinking that the biting was still a kiss (sort of), she bites him several times, pushing him to the floor to bite his ear that begins to bleed.
- She was in Sablier when the city was dragged into the Abyss. Alice wanted to forget about that event, because it was a very painful one. In her memories we see Jack Vessalius, the hero of 100 years ago. It is revealed that she's actually Lacie's daughter. Lacie was impregnated by Levi Baskerville before being cast into the Abyss as a sacrifice for the ceremony of the new 'Glen' and Levi's experiment, to gain the power of the Abyss through a vessel, Lacie's child. While in the Abyss, Lacie gave birth to 'twins', Alice and Alice who would be merged with the Core of the Abyss and called The Will of the Abyss by Levi. In Chapter 70, it is revealed that Alice is not the real B-Rabbit; Oz is the true B-Rabbit and was originally a stuffed animal that Alice was very close to and kept when imprisoned. After Jack began the Tragedy of Sablier he came to Alice's tower to ask the Intention of the Abyss for more power. Alice refuses to allow Jack and the Intention to destroy the world and sever the chains and thus commits suicide stabbing herself with a pair of scissors.
- Alice is voiced by Yukari Tamura (Drama CD) and Ayako Kawasumi (Anime).
- Jack Vessalius (ジャック＝ベザリウス Jakku Bezariusu )
- The 'hero' of 100 years ago and the one who 'defeated' Glen Baskerville. He is revealed in Chapter 65, that it was he who caused the Tragedy of Salbier. He has some sort of connection with Alice's memories. Jack looks like a grown-up Oz with a long plait. His personality is also similar; Like Oz, he does things at his own pace and is loud and cheerful. Oz and Gilbert meet him when they are taken to the Cheshire Cat's dimension. He is currently residing in Oz's body and can 'possess' Oz and speak through him. When in control, Jack also has full control of Alice's chain power. Jack was the third son of the Vessalius family who was, before the Tragedy of Sabrie, a third-rate noble family. Thus, with no expectations from his family, he acted quite freely: always smiling, joking and flirting with girls. Jack was also a self-proclaimed music box maker. His best friend at that time was Glen Baskerville. Jack crafted a pocket watch for him and Glen wrote the melody, titled "Lacie". The pocket watch's melody was said to be a song that Lacie always sang to herself. Later, Glen tried to kill Jack because he started the Tragedy of Sablier (because he believed that without Lacie, there was no meaning to life) Although hailed as a hero for this act, Jack did not want to kill his best friend. In a later entry in Jack Vessalius 's diary, he wrote: "I have killed my best friend. Please... Please do not call me a hero." But it was revealed, that it was Glen who actually wrote this. He also shows true anger when Lottie suggested that he killed Glen to gain fame and glory. Jack reveals, through his speech when he first possesses Oz, that Glen is still living. Despite this, he says to the Baskervilles that if they wish to repeat the past, he will once again turn his body into a blade that will destroy the Death Gods. It seems that all of the things he has said were all lies. During Jack's flashback he was told by Lacie to become a prostitute to which he remarked, 'It is a great sin!' Jack deeply loved Lacie and after she was cast into the Abyss as a sacrifice for Levi Baskerville's experiment, he came to loath the Baskervilles. When Jack learned that Lacie had given birth to a daughter (Alice) while in the Abyss, who was now a 'prisoner' of the Baskervilles, he swore to protect her. However, Jack only cared and protected Alice because she served as a conduit for Jack to communicate with the Will of the Abyss. In Chapter 70 it is revealed that Jack is not trying to possess Oz's body; the body has always been Jacks. Oz is revealed to be the true B-Rabbit, a chain created by the Will of the Abyss at Jack's request, who possesses the power to sever all the chains keeping the world from plunging into the Abyss. This has always been Jack's true intention, to bring the world that Lacie loved to the Abyss, even though she was more or less destroyed by the darkness already.
- Jack is voiced by Daisuke Ono.
- Oscar Vessalius (オスカー＝ベザリウス Osukā Bezariusu )
- Oz's uncle. He is easy-going and very caring. Oscar was the one who found Gilbert and brought him to the Vessalius Dukedom. Both Oz and Gilbert treat him as a father figure. He gets along well with Break. When he received a letter from Ada (in which she stated that she had found someone who she likes), he took Oz, Gilbert and Alice to Lutwidge. He was said to be married to a sickly woman and had hopes of bearing a child. It's assumed she died without the chance to bear a child, as the camera he was going to use to take a picture of his son with was never used.
- Oscar is voiced by Hideyuki Umezu.
- Ada Vessalius (エイダ＝ベザリウス Eida Bezariusu )
- Oz's little sister who adores him very much. After 10 years she attends Lutwidge (ラトウィッジ), a prestigious school for nobles, of which she is a prefect. She keeps in contact with Oscar via letter and causes Oz and his friends to sneak into Lutwidge as she wrote that she has found a person she likes. It is revealed that she was the one who gave Gilbert his precious hat, that made Oz and Oscar think that Gilbert is the one that Ada likes. Then she asked Oz to let her be the one to return Elliot's bag, but when Oz said that he will return Elliot's bag by himself, Ada was slightly disappointed. However, in the later chapters she is seen on a date with Vincent. She has a cat named Dinah and later another one named Snowdrop. It is revealed later, much to Vincent's astonishment, that she has been studying about the Abyss and the occult in order to find a way to bring her brother back from the Abyss, but, during her studies, she has grown an interest in the occult.
- Ada is voiced by Kaori Fukuhara and Ai Tokunaga (Drama CD)
- Zai Vessalius (ザイ＝ベザリウス Zai Bezariusu )
- He is Oz and Ada's father. He appeared only in a flashback until chapter 39. He is depicted with a cold attitude toward his son and explicitly rejected him. In chapter 40 it is shown he has a large scar across his face and is responsible for sending his son to the Abyss. He controls the chain named 'Griffin'. Although the Duke Nightray tells Elliot to hate the Vessalius , he and Zai seem to be friends. It was revealed that he was who planned sending Oz to the Abyss, along with the other Baskervilles. He knows where the Baskerville's final door was. He sent Oz to the abyss with the power of his Griffin. He was protected by Gilbert from being slashed by Oz. He believed that Jack is the cause of his stillborn son and wife´s death, to the point he thinks Jack also killed his brother´s, Oscar, wife and child.
- Rachel Cecile (レイチェル＝セシル Reicheru Seshiru )
- She is Oz and Ada's mother. Not much is known beyond the suspicion that the Nightrays caused her death.
Nightray Dukedom 
- Gilbert Nightray (ギルバート＝ナイトレイ Girubāto Naitorei )
- Also known as Gil or Raven. He is Oz's best friend and loyal servant. Oz is his most important person, for whom he is willing to sacrifice anything; this protectiveness is compounded by the fact that he was brainwashed by Miranda Barma to protect Jack Vessalius (and therefore Oz, who is his medium) even if it means killing. When Gil is drunk, he reverts to his fourteen-year-old self, an insecure crybaby. He cares deeply about the hat that Ada gave him. He is a great cook, terrified of cats, unable to quit smoking in eight attempts, and constantly afraid that as Oz grows, he will be left behind.
- Gil is shown to have become close to Alice, despite his constant arguing with her. Though at first wanting to kill her in chapter 35, Gil saves Alice when she falls down in a small rockside later in the chapter.
- According to chapter 65, Gil was Glen's servant 100 years ago in order to fulfill his duty of being the next Glen after Oswald, and he is also a Baskerville, due to his ability to be greatly wounded, but not killed. He was nearly killed by Jack. And in order to save him, his brother Vincent opened a path to the Abyss. (It is later revealed that Gil was killed in order to serve as Glen's new vessel, and when Vincent interrupted the ceremony the Tragedy occurred.) He was taken in as a servant by the current Vessalius family fifteen years ago, after he was discovered injured and amnesiac in the Vessalius gardens. He came to be Oz's closest friend, and was invited to be a part of the boy's coming-of-age ceremony. During the ceremony, Zwei uses her chain Doldum to control his body and forces him to attack Oz. After he regains consciousness, he recognizes one of the Baskervilles as Oz's father and when Oz attacks the man with a sword, Gilbert takes the wound and falls unconscious.
- Gil remains loyal to Oz during his time in the Abyss. Shortly after the ceremony, he is approached by Xerxes Break who arranges his adoption into the Nightray family in exchange for inside information on the family's doings. He views this as a betrayal, since the Nightrays are the prime suspects in the assassination of Oz's mother, but he agrees to join the family when he learns that contracting their chain 'Raven' might give him the power to rescue Oz. He trains in gunmanship and eventually kills the Nightray family before the chain deems him worthy to contract with it.
- Once he obtains the chain, he takes the name Raven and goes to work for Break as a member of Pandora. When Oz returns from the Abyss, Gil is the first one at his side. Initially, Oz is unaware that 'Raven' is Gil, but during the second battle with Zwei his true identity is revealed. Gilbert uses his chain's power to bind B-Rabbit, keeping Alice in her human form and preventing Oz's seal from moving when they are not in battle.
- It's shown in Retrace 45 that he has always had the right to make the contract with Raven, which leads him to gaining the chain. It is also said that Gilbert had been poisoned on a targeted attack against the Nightrays by a mysterious headhunter. As of Chapter 69 Gil has gotten all of his memories back of Sablier and the Tragedy from 100 years ago, his true master is Glen, who's soul lies within Leo, and by Chapter 74 Gilbert shot Oz by Glen's commands.
- Gilbert is voiced by Azuma Sakamoto (younger), Katsuyuki Konishi (CD drama), and Toriumi Kousuke (Anime) (older).
- Vincent Nightray (ヴィンセント＝ナイトレイ Vinsento Naitorei )
- Vincent is Gilbert's younger brother by one year. As the Vessalius family found Gilbert, the Nightray family similarly adopted Vincent. His left eye is golden like Gilbert's, but his right eye is wine-red and his long hair is golden in color. He loves his brother Gilbert to the point of slight obsession. He has an easy-going personality on the outside and is often seen smiling. However, it is shown that Vincent also has a dark, unstable side. He has a habit of carrying around scissors and cutting up stuffed animals with them. Break is often at odds with him, referring to Vincent as a dirty 'rat', which is fueled by Vincent sending Echo to attack Sharon.
- Vincent is from 100 years ago. In Alice's memory, a young Vincent is seen walking among corpses, gouging out eyes and intestines with a pair of scissors saying that "It's not my fault, it's that person's fault, it's all because of that person," he was doing this to save his brother. He is also shown to be in alliance with the Baskervilles. It was him who called Zwei out from Echo, telling Echo that she is not required anymore in order to release her other personality. He is seen going on a date with Ada Vessalius shortly after those events. In one of the most recent chapters that gives some insight into their date, they are discussing the situation concerning the Headhunting. Meanwhile his true thoughts show that he may be planning to harm Ada in order to draw Gilbert's attention, believing that she is an important person to Gil. Later chapters have shown that he has become Ada's lover in order to "taint her" as well as make her a pawn in order to retrieve the Key to the Abyss from Oscar Vessalius.
- Later chapters showed some of his time during 100 years ago. Due to the belief that red eyes will bring disasters, Gilbert and Vincent used to live on the streets where people would attack them whenever Vincent's eye was revealed. This continues until Gil and he are selected as Baskervilles. Vincent was fond of Jack Vessalius, who didn't care about his eye and even cut Vincent's hair which was used to hide his red eye, stating that Jack "loves" it. It was also shown that Jack tried to introduce the two to Alice since they were in closer age to her. Unfortunately, Alice immediately made fun of Vincent's red eye which caused Gilbert to pull her hair. This incident fueled Vincent's hatred towards Alice since she had made Gil "showed that kind of expression again" and Jack sighs in worry and began his habit of tearing up dolls (often rabbits) out of frustration and hatred. He was the prime suspect of Alice's death because of his hatred and his placement in Alice's memories until it is revealed later in the series that Alice committed suicide because of Jack. In one flash-back, Vincent is shown threatening Alice and even giving her the corpse of her cat, Cheshire, after he'd gouged the cat's eyes out.
- When Vincent found out about Gil's death and how he will be Glen's next body through a ritual from Alice, he was visited by a mysterious lady (later revealed as Miranda Barma) who told him how to prevent the ritual by opening the Abyss's door. It is revealed later in the series that Jack and she had used Vincent as a tool to open the Gates of the Abyss by using his abilities as a "child of misfortune". Believing in them, young Vincent opens the door, playing a major role in causing the Tragedy. He is engulfed by the Abyss with the whole city and his brother, and is returned to the world after 100 years had passed in the world.
- Vincent has a legal contract with the Doormouse.
- It is revealed in Retrace 61 that he was the real headhunter all along and had formed an illegal contract with a chain called Demios. He also forms a pact with Leo asking him to either kill him or erase his existence from the world so that his brother, Gilbert, can "stay in the sunshine forever."
- Vincent is voiced by Jun Fukuyama (older) and Fuyuka Ōura (younger).
- Echo/Zwei (エコー Ekō )
- Vincent's personal servant. She is somehow emotionless, like a puppet and she treats Vincent's words as law. Oz calls her "Echo-chan". Echo fights with blades that come out of her long sleeves. It may seem that Vincent treasures her, but he actually does not care that much. In Chapter 23, he goes as far as to poison her to prove that the antidote for the poison that he poisoned Sharon with works. Echo is shown to have her own mind when she saves the bottle of antidote that Vincent almost drops off the veranda, because she remember what Oz said the first time they meet. In Chapter 33 she admits that she finds Vincent annoying. She seems to developed feelings for Oz after both of them go to the festival together and Oz shows her what it is like to have fun, he also gives her a hair ornament which he was supposed to give to the girl he likes, although he didn't know that. In recent chapters she is known to have another personality called Noise, who is actually Zwei. Zwei loves Vincent deeply and, according to herself, is the original personality inside Echo's body. Zwei controls a chain called Duldum that can control other people or immobilize them using strings. Zwei used her chain to immobilize Gilbert, and also used it within Echo to capture Sharon.
- With Zwei in possession of the body, she rejoins the Baskerville group and goes to Sablier along with Lottie, where she meets Elliot and Leo. She immobilizes Leo using her chain, Duldum, but is only able to control his body, not his mind. Meanwhile Lottie stops Elliot. It is shown that Break thinks it's unfair for him stabbing her through the hand and stomach after she had saved the antidote that saved Sharon Rainworth's life.
- Echo is voiced by Ryō Hirohashi.
- Elliot Nightray (エリオット＝ナイトレイ Eriotto Naitorei )
- A student at Lutwidge that, along with Reo, catches Oz's attention as they can play the tune from his pocket watch. He first meets Oz in the Latowidge library where they get into a fight over a character in the novel series "Holy Knight" (Elliot spoils the ending for Oz's favorite character, Edgar). He also doesn't like Ada calling his name and despises how the Vessalius seem to get away with anything just because they were heroes 100 years ago. Ada, however, thinks he is a nice and dependable person deep down. He is the legitimate heir of the Nightray Dukedom and consequently the brother of the adopted Vincent and Gilbert. He is adept with the sword and keeps a blade with his family crest in a violin case. Elliot has a strong sense of right and wrong and tends to say things without consideration to the other party. It is through this straightforwardness, however, that Oz finally overcomes the shadows of his past. He has said that the tune he and Leo were playing was composed by him and is called "Lacie", implying a strong connection between him and Glen Baskerville. He is also shown to suffer from nightmares, which later on in Chapter 39 is implied that Eliot possesses some of Glen's memories. Elliot meets Oz and co. at Sablier in chapter 34. He takes them into the Nightray's orphanage at Sablier, where Oz meets Phillipe. Elliot sticks up for Oz when Zai shows up.
- After these events, Elliot hears about a mysterious killer known as the head hunter who in the past was targeting members of his family, also killing his brothers. Upon hearing that there was another murder committed by the same person, he attempts to find the killer himself.
- In chapter 49, Elliot is shown worried about Reo, since he hasn't talked to Elliot a lot lately, and seems to be feeling unwell at Oz's second coming of age ceremony.
- Elliot is also shocked when he sees Reo talking to Isla Yura, and wonders what their connection may be. He seems to be upset that Reo didn't tell him anything, ending up in a heavy fight with him.
- In Retrace 52, Elliot faints with a vision of his nightmare where he kills everyone with his sword and after waking up and finding Vanessa dead, Break accuses Elliot of being the Headhunter. In Retrace 57, it is found that he is the Headhunter.
- In Retrace 58 it is revealed that during a past trip to the orphanage in Sablier he and Leo went looking for several missing children that had wandered into the hole that connected to the Abyss. They found two of the children killed and upon Leo finding a third child, they were attacked by one of the orphans that had lost control of Humpty Dumpty. Attempting to protect Leo, Elliot was skewered by Humpty Dumpty and almost died. Leo stopped Humpty Dumpty and made Elliot drink its blood and pronounce its name in order for Elliot to form a contract and be saved. Elliot forgot everything afterwards, believing that he had only 'slipped, hit his head, and was knocked out on the ground'. He later overhears his older brothers Claude and Ernest talking about murdering Gilbert and Vincent. They had planned to set fire to their house while their mother, Elliot, and the rest of the household escape, leaving Gilbert and Vincent to burn to death. Elliot, enraged, attempts to come out of hiding to confront them when Ernest adds that they will also kill Leo. Overcome with shock, Elliot unconsciously summoned Humpty Dumpty and killed his brothers. Humpty Dumpty causes him to once more forget what he had done and he has been living in denial since. However, since he remembered everything in Retrace 58, the wounds from before he contracted with Humpty Dumpty return.
- As it turns out, the supposed implications of Elliot being the next container of Glen Baskerville is false. The memories from Retrace 39 are actually from when he killed his brothers, not from the Tragedy of Sablier. It is in fact Leo who had written the revised version of 'Lacie' and Elliot claimed credit because of his anger at Oz.
- In Retrace 59, Elliot is asked by his chain (Humpty Dumpty) to forget all that he has just remembered. Elliot wants to remember however it is against his chain's wishes. Vincent tells him that by rejecting his chain, he could perform a double suicide with his chain. Realizing that If he were to stay alive, other people would have to carry the burden of his life as well as the fact that he was soon going to die anyway (due to the injuries that reappeared and his seal's revolution) he decided to reject his chain; both he and Humpty Dumpty died.
- In Retrace 61 in a flashback during when Vincent was with Elliot nearing death Elliot whispered something to Vincent that need to be delievered to Leo. Vincent told Leo that the message was "I'm sorry, Leo."
- Elliot is voiced by Hirofumi Nojima
- Leo Baskerville (リーオ＝バスカヴィル Rīo Basukaviru )
- A boy with dark messy hair and round glasses. He is a student at Lutwidge and serves Eliot. He has a calm and collected demeanor and is hardly rattled by anything. Leo is very observant and discovered Oz's identity as an intruder. Despite being Elliot's servant, he doesn't always take his side and will make him apologize if needed. Also, Leo could hit Eliot if he's doing or saying something wrong to his eyes. He is rarely seen without Eliot. Leo carries a gun and is apparently hopeless with it and swords, according to Elliot. In chapter 49 Eliot witnesses a friendly little chat between Leo and Isla Yura, wondering how they are related. Leo thinks Isla Yura is the culprit of the deaths of six children of the orphanage and the one who made Phillipe forget about his fathers's death; being this the first time we get to see him acting saddened, angry and restless.
- In retrace 50 Leo tells Oz the way he and Eliot met two years ago, revealing that they indeed disliked each other at first but with the mutual love for piano they developed a bond through music. Eliot says Leo always beat the people who tried to cut his hair. When Eliot asks why he wants to hide his eyes (since they are such a "beautiful color," according to Eliot's thoughts) Leo answers that he doesn't want to hide his eyes but he doesn't want to see. Eliot doesn't get it and Leo responds that he doesn't want to see the world. Leo asks him to buy him a pair of glasses so that everything would be fine (it means he doesn't really need them.)
- Leo rejected Eliot when the second asked him to be his servant, but at the end he accepted because "he was interested in the Nightray Household's books collection".
- Leo tells Oz he reveres Eliot and that he'd kill any of Eliot's enemies even if it's Oz or himself and also asks Oz to kill him with his own hands if he ends up being the main suspect of danger. :In Retrace 58 it is revealed that he is the one who made Elliot become a contractor. He is also the one who composed 'Lacie'. While panicking for Elliot who had been fatally wounded by Humpty Dumpty, mysterious figures appeared in his mind and told him the only way to save Elliot would be to make him for a contract with Humpty Dumpty. It is later on shown that one of the figures is Glen Baskerville, making Leo the next 'container' for his soul.
- In Retrace 61 Vincent goes to ask Leo a favour saying that he will serve him in return also letting him know that he is the head of the Baskervilles. Leo agrees but only if he would cut his own hair (which we know from Retrace 50 that he almost killed a man trying to do so) due to him being "tired of hiding." Leo's face is revealed to be almost identical to Alice's. According to the text around the previous page, his eyes are black with pools of reflected light; like the abyss. Later in chapter 63 it is revealed that recent events have driven him insane. After Leo asks Oz to join him to try to repeat the Tradgey of Sabrier, and Oz refuses, Leo tries to send him into the Abyss, but fails when Gilbert uses Raven on Leo's Jabberwock. After being taken down by Jack using B-Rabbit he eventually gets up again and Oswald's soul, which resides within Leo, took over his body and ordered Gilbert to shoot Oz/Jack as he was his servant.
- Fred, Claude and Ernest Nightray
- Older brothers to Elliot Nightray who were killed by the mysterious head hunter seen in Chapter 45. Fred was the first to be killed, which resulted in Ernest and Claude going after the head hunter while instructing Elliot to flee the country with their mother. The brothers appear to have disliked Vincent and Gilbert, warning Elliot to stay away from them as they did not consider them a part of the Nightray family. Elliot himself they seemed to have dotted on. Claude was upset with their father for allowing Gilbert to form a contract with Raven as he was not a descendant of the Nightray family. Ernest is the one who tells Eliot that as he's already fourteen, he needs a servant (in a fashion way), and then takes him to Sablier to choose between the orphans. Claude and Ernest ended up getting scolded for taking him to Sablier before he matured like his father wanted before telling him about Sablier.
- Vanessa Nightray (ヴァネッサ＝ナイトレイ Vanessa Naitorei )
- Elliot's older sister, not much is known about her but she seems to dislike Oz. It is known that Vanessa and Elliot were very close and that she taught him of things like the language of flowers. In Retrace 52, Vanessa becomes another victim to the head hunter (Elliot) thus being beheaded just like Fred, Claude and Ernest before her.
- Bernice Nightray (ヴァーニス＝ナイトレイ Vānisu Naitorei )
- The mother of Elliot, Fred, Claude, Ernest and Vanessa. It is said that her sanity began to crumble when her eldest sons were murdered by the headhunter. She was then manipulated by Isla Yura, and became part of his cult. In Retrace 56, she is shown greeting Elliot in a room where Reo lies on an altar, ready to be sacrificed for the purpose of Yura's ritual, much to Elliot's horror. Not much is known about her other than the fact that she is clearly insane. She is killed in Retrace 57 by Elliot when she attempted to sacrifice Leo.
Rainsworth Dukedom 
- Sheryl Rainsworth (シェリル＝レインズワース Sheriru Reinzuwāsu )

Also she is mother of Shelly Rainsworth, and grandmother of Sharon Rainsworth. She appears as a wheelchair-bound elderly woman which makes her get underestimated by many who see her, though she is exactly the opposite of what people may think. Sheryl herself is generally a very happy and cheerful person, even in the most serious circumstances, though she can be very dangerous when she needs. Somewhere along the line Sheryl was apparently crippled and has since been in a wheel chair. She obtained the chain Owl to lead the family within Pandora, though she did so long after her close friend Rufus Barma had contracted with Dodo.
- Sheryl Rainsworth was meant to appear at Oz Vessalius' coming of Age Ceremony but she became ill and had to have her daughter, Shelly take care of her, so she sent Sharon in her place. She possess a sharp-bladed fan, like Rufus Barma and Sharon Rainsworth, and uses it as her weapon. Once she stopped the fight breaking out between Oz and Rufus, who was about to attack Oz with his metal fan. Sheryl threw her own fan directly between those two and it got in a pillar behind them, shocking all in the room. Sheryl was the one who stopped Rufus from arresting Xerxes Break, as well as taking Alice into Pandora for her relationship to The Intention of the Abyss. She was one of the first who noticed that Break became blind.
- Duchess Rainsworth is very close with Rufus Barma, who she calls "Ruf", since they are childhood friends. To protect him, she often lets him to play her valet when they are in public, while Rufus creates an illusion of himself to occupy his position within Pandora. They are often seen discussing new information and future plans. It's believed that Rufus has love feelings for Sheryl, but she doesn't return them. Also it is suggested that Duke Barma is the one who attacked her in manga Ch. LXIV.
- Sheryl didn't use her true power yet, but she is considered to be the most powerful and scariest of the four dukes.
- Sharon Rainsworth (シャロン＝レインズワース Sharon Reinzuwāsu )
- The Lady of the Rainsworth household. Sharon is a member of Pandora and looks like a fourteen-year-old girl, although she is technically 23 years old. Her appearance does not change from her first meeting with Oz to after he came out of the Abyss because she has a legal contract with a chain, the black unicorn Eques. Sharon and Break have a close relationship. She was the one that discovered Break in a fatal condition after he came out of the Abyss. When she was young, she used to call Break 'Xerx-nii', as he was like a big brother to her. She wants to be of use to him. She also looks a lot like her mother, Shelly Rainsworth. While Oz and co. were taken into the Cheshire Cat's dimension, Sharon was abducted by Echo under the orders of Vincent Nightray, who poisoned Sharon in order to blackmail Break into destroying the memories from the Tragedy of Sablier that Break attained from the Cheshire Cat. Despite Sharon protesting to Break to not destroy the memories, which took the form of the bell Cheshire wore around his neck, Break destroyed the memories in exchange for the poison's antidote. Sharon develops a queen complex when she drinks, which Oz strangely finds cool. She likes the concept of "love" and tries to teach Alice about it. In episode 20, she wanted Alice to call her "big sister." In the second DVD special, she tries to teach Alice "her status as a female." Also in episode 20, she beat Oz with a paper fan after Alice told her that she and Oz already kissed, later apologizing.
- After Oz and co. return from Sablier, Sharon realizes Break still thinks of her as fragile. She then makes a resolution to be of more use to Break, and joins Oz, Gil, and Alice when they go to locate a seal encasing one of Jack's body parts. While at the location of the seal, the group is attacked and Sharon realizes she takes the power of her chain for granted. Since then she has decided that she is powerless but is determined to get stronger.
- Sharon is voiced by Yui Horie (Drama CD) and Hanazawa Kana (Anime).
- Xerxes Break (ザークシーズ＝ブレイク Zākushīzu Bureiku )
- Commonly known as Break, he is a member of Pandora and a servant of the Rainsworth Dukedom. Break's appearance does not change from the ten-year gap between Oz entering and leaving the Abyss. He has a contract with the Mad Hatter. Break is often seen with a doll on his shoulder, which he calls Emily. He adores sweets and cakes. From the outside, Break seems like a carefree character, never serious and always smiling. When needs be, however, Break shows his dangerous and evil side. Reim tells Oz that Break has not always been the way he is now. Before, after losing his eye, he was a bitter and angry person, never smiling. However, through the kindness of Shelly, Sharon's mother, he began to open up. He has sworn absolute loyalty to Shelly.
- Break has no left eye. He reveals that the Intention of the Abyss took it from him and that the Cheshire has it. Break's true motive is to find the truth behind what happened 100 years ago. He hates Vincent with a passion.
- It was revealed by Rufus Barma in chapter 29 that his real name is Kevin Regnard. Break was originally a knight who served under the noble family Sinclair until they were mysteriously massacred for political reasons. His lord was killed during the incident while Break and the daughter of the lord were out. Break blamed himself for his carelessness, and became an illegal contractor with a chain named Albus the White Knight to try to change the past. When his clock made a full revolution, he was pulled into Abyss where he met the Intention of the Abyss and a young Vincent. The Intention of the Abyss once changed the past for Break. In return, Break was asked to fulfilled her wish. Her wish was to not be the Will of the Abyss anymore and to help her save Alice, according to Chapter 63 in the manga. Break then was sent to the Rainsworth house over 30 years later of his own time.
- The changed past wasn't really what Break wanted. The Sinclair family was still murdered. According to Sheryl, the oldest daughter of the house was assassinated, which led the younger daughter to become an illegal contractor and got sent to Abyss after her Chain murdered the entire family. The political massacre did not happen and Break's lord lived for 4 years longer, but instead, the little girl who originally survived the incident died. Break blames himself for that. For one moment he also blamed the Intention of the Abyss, but he realizes that he was the one who asked for the past to be changed, and in reality, he really just wanted to erase his own guilt. In Retrace 42, it is shown that Break has lost his eyesight, causing him to be blind. It is later revealed in Chapter 43, however, that Break has not gone completely blind' although he can no longer discern faces, he can make out general objects. When he and the others learned the truth of the Tragedy of Sablier, Break stole the earrings Rufus had taken from Sheryl earlier only to have them be stolen back and after hearing that Oz was in trouble, ran towards the direction of the sound of the chains breaking.
- Break is voiced by Toshihiko Seki (drama CD) and Ishida Akira (anime).

- Sheryl Rainsworth's daughter, and Sharon Rainsworth's mother. She seems looks like an older version of Sharon. She is only seen with a blue flower dress and a dark purple choker with a green jade on it. It appears that she was a loving mother and that she cared greatly for her daughter, Sharon. She has only appeared in flashbacks as the one whose kindness managed to get through to Xerxes Break during his long depression after returning from the abyss. Break also mentions her as the reason he gave up Cheshire's Bell to save Sharon, saying Shelly would kill him, if anything happened to her daughter.

- Voiced by: Yūya Uchida
- The last of the four dukes. Rufus is known as the longest living duke and is a very knowledgeable person. He holds information on almost all topics and even knows people's personalities and is thus able to predict their reactions. He absolutely detests people changing without him knowing as then he would not have the most updated information. Oz and co. approach Rufus to seek information about the Tragedy of Sablier. Rufus first appears as a round man with a big mustache wearing a big teacup shaped hat. Later, after getting destroyed by Break, it is revealed that the real Rufus created that as an illusion. The real Rufus has long red hair, tired looking eyes and speaks in olden-day Japanese. He was sought by Oz in order to learn more about the Tragedy of Sablier, but instead, they learned about Break's past from him.

It is revealed in chapter 49 that Reim is a contractor, and in chapter 51, that his Chain is March Hare, any powers it may have are said to be useless for fighting but what it is exactly has yet to be revealed. He and his team was attacked by Lily who kept him alive, at first because she wanted to have a contractor battle and then because she wanted to be his friend. Despite his qualms about a little girl being one of his enemies, he shot Lily in the head when she nonchantly revealed that the Baskervilles would perform another massacre if Glen ordered it. He appeared to have been killed by Lily precipitating a fight between Break and the Baskervilles.

Residents of Baskerville 
- Glen Baskerville (グレン＝バスカヴィル Guren Basukaviru )

Glen's next body was supposed to be Gilbert with Raven as the chosen Chain.
- Levi (レヴィ Revy )
- Levi was the head of Baskerville household before Oswald and is the father of Alice and The Will of The Abyss. Levi was shown to be sarcastic and find things to be fun in most ways. He has strange way of showing his humorous side. Although, he can be serious when needed. He took a quick interest in Jack and gave Jack the way to the secret passage to enter the Baskerville mansion whenever he wanted to. It was also revealed that he had taken care of both Oswald and Lacie since they were children. Before Lacie was cast into the abyss, he impregnated her as part of his experiment to uncover a way for people to control the power of the Abyss, and that he would do this by supplying the Core of the Abyss a human vessel. After giving his last Chain, Jabberwock to Oswald and the latter becoming the next Glen, he confronted Jack and revealed everything about the reason why Lacie was cast into the Abyss and left everything to Jack to finish what he had started with his experiment, knowing that he wouldn't live long to watch the result as his body was soon going to become the Chain Humpty Dumpty. He met up with Jack once more before his death and explained to him about the chains that held the world together and that without them the world would fall into the Abyss.
- Oswald (オズワルド Ozuwarudo )
- Oswald was Lacie's older brother and Jack's supposed only best friend. He was the next Glen after Levi. According to Lottie, Oswald (who was already known as Glen at the time) gave the impression that he liked being alone and was difficult to approach. He was also shown to be an honest person, revealing his interest in Jack to the point that it made his skin crawl directly in front of his face. This made Jack at first, afraid of him because he felt that he could see his true nature, though later they eventually becoming good friends. At the day of the ceremony he officially became Glen, he sent Lacie to the Abyss with his own hands, and since then trying to atone for killing his sister. Jack and Oswald made a musical pocket watch together. Oswald wrote the melody for it while Jack crafted it. The piece he wrote is called "Lacie" name after his sister as it was the tune she would hum often. It was revealed in Chapter 65 that it's his head which is sealed on the sealing stones and in 67 that Miranda Barma has an obsession for his head. When Jack opened the Gate of the Abyss using Vincent within the Baskerville Mansion during Gilbert's first Transfer Ceremony, Oswald halted everything and told the Baskervilles to kill everyone so that the humans could return to this world after a 100 years cycle instead of turning into Chains.
- Oswald is voiced by Kishō Taniyama.
- Lacie (レイシー Reishī )
- Lacie was a member of the Baskerville household and Oswald's younger sister. The melody that Oswald composed was named after her and the song she sang. She died as a sacrifice made to the Abyss. The tombstone where Oz found the pocket watch is her tomb. She resembles Alice greatly, sans her red eyes of misfortune and darker colored hair. She found Jack on the streets after getting upset with Oswald, so she traveled with him to kill time. She went back after the Baskervilles found and delivered Oswald's message that he apologized, leaving Jack one of her earrings and told him to find her by remembering the name Baskerville. She is later revealed to have returned Jack's feelings because he was so faithful to her. She's rather eccentric, despising common sense because according to her, one has to look at the world from different angles to appreciate it. She is shown to be rather sadistic, as when she killed people who intended to sell her in the same manner as the Will of the Abyss. Levi had impregnated her before she was cast into the Abyss and she had given birth to twins; Alice and the Will of the Abyss. She is also responsible for the creation of Oz as she brought the Core of the Abyss one twin stuffed rabbit who gained a personality and whom Alice would later name 'Oz'.

- A bubbly girl with pink hair that kidnaps Oz at Lutwidge. She was a participant in the Tragedy of Sablier and killed many under orders. She served the Baskerville house and had feelings for Glen 100 years ago. Her real name is Charlotte, but Jack gave her the nickname Lottie after they met. Lottie can't forgive Jack for killing his supposedly best friend and object of her affection and thus is targeting Oz to talk to Jack. Her main objective was to find their master Glen, and to find out what actually happened on the night of the Tragedy of Sablier. Although she was one of the participants, she acted upon orders, and knew nothing behind the scenes. Hence why they approached Jack for the answers. She controls a chain called "Leon". Break has begun a "friendship" with Lottie as of chapter 41. Retrace 51 implies that Lottie, along with the other Baskervilles, is immortal, as they are "special beings chosen by Abyss." It appears the Baskervilles are more like Chains than humans at this point which makes them susceptible to Mad Hatter's power.
- Lottie is voiced by Megumi Toyoguchi.
- Fang (ファング Fangu )
- Fang has spiky hair and a tattoo down the left side of his face. He was also a participant in the Tragedy of Sablier. Fang speaks politely and is the most rational of the trio. He wields a large blade. Retrace 51 implies that Fang, along with the other Baskervilles, is immortal, as they are "special beings chosen by Abyss." Despite this, in Retrace 56, Break stabs him through the stomach and he dies by dissipating.
- Fang is voiced by Takayuki Kondo.
- Doug (ダグ Dagu )
- Another member of the trio. It's vaguely shown under his hood that he has a tattoo opposite of Fang's on the right side of his face. Not much has been revealed about him. Retrace 51 implies that Doug, along with the other Baskervilles, is immortal, as they are "special beings chosen by Abyss."

- Lily (リリィ Rirī )
- She is the latest Baskerville to be released from the door of the abyss that the Baskervilles own. A little girl that cries a lot. She controls a chain known as Bandersnatch that is a canine chain. Her mentality goes from an innocent child to a raging psychopath in seconds. In Retrace 51, it is show after being shot in the head by Reim, that she cannot die (she had also revealed how one becomes a Baskerville). She desires Reim's friendship and is deeply hurt by his rejection, but was happy to see him alive, a big smile on her face when he called out her name. However, that split second distraction almost got her killed and killed Fang who threw her out of the way and took the fatal blow himself. She also hates Gilbert for having Raven as his chain.
- Philippe West (フィリップ＝ウェスト Firippu Wesuto )
- Philippe is a young child from a wealthy family, though without a mother and father. Oz saved Philippe from some bullies, and while talking to him saw a reflection of himself in Philippe, particularly that of his father. Phillipe was then attacked by Echo, who was in pursuit of an illegal contractor. Echo took Phillipe and was about to chase after his father, the illegal contractor, and use him as a hostage. However, Oz managed to interfere with the process. Philippe's father made an illegal contract to try to bring his wife back to life but lost control and was eventually killed by Vincent on grounds that he was about to kill Oz.
- After the death of his father, Philippe was taken to the Nightray's orphanage at Sabrie. There, Oz meets him again. Oz tries to apologize for not being able to bring his father back. Philippe denies that his father is dead by saying that he has received a letter from his father. He is later seen talking on the phone with his father, although the phone cord is shown to be severed, leading one to suspect that Philippe is mentally unstable. He is seen again in Retrace 52 at the party taking place at Isla Yura's place when he shows up with Alice wearing a cloak similar to that of the Baskervilles. When Oz and Alice ask him why he's there, he tells them that the kids from the orphanage are participaiting in a 'play' about the Tragedy of Sablier. He and the other House of Fianna children are contracted by the Chain Humpty Dumpty.

- The Head hunter, also known as Humpty Dumpty, is a mysterious killer and a Chain who had targeted the Nightrays in the past, killing Elliot's elder siblings. Humpty Dumpty made its appearance known in Retrace 44 killing everyone in the mansion. The head hunter then proceeds in releasing the seal trapping Glen's soul. Humpty Dumpty has connections with the Baskervilles, as he is the body which Glen Baskerville had before his new one. When Glen transferred from that body, the body became Humpty Dumpty. His motives are unknown. The head hunter seems to have a connection with Isla Yura and the religious cult Yura leads. It was then later mentioned by Glen that the Head hunter was actually the previous Glen's body. (He said, "once my soul leaves my body, it will turn into a chain." and that "Humpty Dumpty is the transformed body of the previous Glen.")
- In the end, it was revealed that Humpty Dumpty's role was nothing more than that of an imitator of the true Head Hunter, Demios, also known as The Queen of Hearts.
- Isla Yura (イスラ＝ユラ Isura Yura )
- Isla Yura is first seen as a worshipper of Jack Vessalius. In Retrace 54, he is revealed to be behind the massacre at his house, in an attempt to recreate the Tragedy of Sablier. He believes that the Abyss is a place of happiness and the real tragedy of the Tragedy of Sablier was that the whole world did not enter the Abyss. In Retrace 56, it's shown that he truly doesn't believe this and is only manipulating the people in the occult for an ulterior motive.
- B-Rabbit (血染めの黒ウサギ (ビーラビット) Chizome no kuro usagi / Blood stained black rabbit(Bī-Rabitto, lit. B Rabbit) )
- Also known as Alice and is contracted to Oz. The 'B' stands for both 'bloody' and 'black'. B-rabbit is the most powerful chain in the Abyss and resembles an anthropomorphic rabbit with black fur, red pupils and fangs wielding a giant scythe when released. B-Rabbit also can utilize several large steel chains with spiked tips that can be used to both attack and bind targets. When she is not in battle, she takes the form of a girl with a red coat with white diamond design and white boots. In Chapter 70, it is revealed that Oz, not Alice, is the true B-Rabbit, and that he was originally a small stuffed rabbit doll that Alice played with while imprisoned before the Tragedy of Sablier. Oz at some point was transformed by the Abyss into a chain and was contracted to Jack.
- Raven (鴉 (レイヴン) Karasu / Crow, Raven (Reibun, lit. Raven) )
- Gilbert's chain. Previously Glen's chain. Sealed by the Nightray family and eventually tamed by Gilbert. Can use teleportation at a great strain to the user.

The first time he disturbed him, the second time he came to visit, and the time when he made the contract. He also said that he'd be bound to Gilbert's left arm again.
- Equus (一角獣 (エクエス) Ikkakujū / Unicorn (Ekuesu, lit. Equus) )
- Sharon's chain. Equus is in the shape of a black unicorn and is often used by Sharon for data collection. It has the power to warp between places and dimensions, taking people with it.

Sharon mentions that although Equus is meant for espionage, it doesn't mean that it's not powerful.
- Mad Hatter (イカレ帽子屋 (マッド ハッター) Ikare bōshiya / Mad hatter (Maddo Hattā, lit. Mad Hatter) )
- Break's chain. It resembles the "Alice in Wonderland" character (Mad Hatter) but gives off a more sinister feel. Mad Hatter resembles a giant top hat with flowery decorations, under which is one big eye. It has the power to reject and destroy the power of the Abyss and exists for the purpose of killing other chains. When Break uses it's power to a large extent, he is seen coughing up blood, but only because his previous identity, Kevin Regnard, had already made an illegal contract with Albus, putting more strain on the Break's body.
- Dormouse (眠り鼠 (ヤマネ) Nemuri nezumi / Sleeping mouse, Dormouse (Yamane) )
- Vincent's chain. It resembles the dormouse of Alice in Wonderland, but much bigger. Yamane has a toy-like tuner on its back and has stitch-closed eyes.

- Cheshire (チェシャ猫 (チェシャ) Chesha neko / Cheshire cat (Chesha, lit. Cheshire) )
- A chain that lives in a dimension created from Alice's memories. He resembles a human form of the Cheshire Cat from Alice in Wonderland. Cheshire was actually Alice's pet cat from 100 years ago. The bell around his neck is the 'truth' from 100 years ago, later taken by Break. The Cheshire cat is a unique chain in that he doesn't need a contractor in order to leave the Abyss (since his residence isn't in the Abyss in the first place). Originally believed to be a fervent servant of the Intention of the Abyss, it later turns out that he is trying to protect Alice's memories that she abandoned, in order to prevent her from suffering pain when she recalls them. Break mentions that Cheshire's eye was his. It is revealed in Break's memory of meeting the Will of the Abyss that Vincent had removed Cheshire's eyes 100 years ago, killing him. Cheshire also has only one eye, since the Abyss only took one of Break's eyes when it showed his memories. Cheshire can also be connected to "Through the Looking Glass" as Alice's cat 'Kitty'.
