Sister Princess (シスター・プリンセス Shisutā Purinsesu?) is a Japanese seinen series written by Sakurako Kimino and illustrated by Naoto Tenhiro. It began as a serialized light novel series in 1999. In 2001, a manga series and a bishōjo game for the PlayStation were released. Sequels to the game were released for the PlayStation and Game Boy Advance. Sister Princess was also adapted into two anime television series.
The premise behind Sister Princess is that an ordinary young man (the player) is made to live with twelve lovable little sisters, each with their own distinct quirks and personalities. The game itself plays out like a dating sim. Players have about a month to spend with the sisters with each day broken up into three segments: first is the free time period before noon, followed by the period after lunch and ending with another period of time before bed. During day time, the player can choose which of the girls he wishes to escort to school, if any. The period after lunch is similar to the one in the morning, with additional choices which allow the player to go to various places in town besides walking home with one of the girls. Every night before bed, the player will be allowed to check his e-mail and send replies. As the player continues to interact with the sisters, their reactions to their big brother will change accordingly until the ending.
There are two different endings for each sister: the normal ending and the "non-blood relation" ending. As the name would suggest, the special ending reveals that the brother-character and sister are not actually related by blood. In the case of some of the older sisters, this can lead to the protagonist and "sister" marrying one another. In the original Sister Princess, the player can see two different endings for each sister, but Sister Princess 2 has four endings for each sister. The first two were the non-sibling relation and siblings-together ending and, if the player chooses one sister in the beginning but ends up with another sister, either of the other two endings for the first sister who the player does not choose appear ("non-blood relation" ending and "still brother and sister forever" ending also) but with a different story.
For Sister Princess 2, the story begins on the final day of school before summer vacation. Then the player chooses a sister who he wants to start with for a close relationship. Therefore, Sister Princess 2 is about spending the player's time with either one sister or all sisters at the same time as they spend their summer together. Especially in Sister Princess 2, the player can spend the summer with all the sisters, not just one, in a special ending where the sisters invite their brother to a summer party where the brother and the sisters would swear to be together forever.
- Wataru Minakami (海神 航 Minakami Wataru?, lit. "Sea God Wandering")
- Voiced by: Kenji Nojima (Japanese), Braden Hunt (English)
- The brother whom all of the sisters adore. In their eyes, he can do no wrong. The name Wataru Minakami was given to the brother character only for the first Sister Princess television series. In Sister Princess Re-Pure, he is simply referred to as "Ani", or "Brother". Until the final set of illustrated stories, the brother's face was always hidden or turned away from the reader to keep his appearance hidden. This follows a tradition of most eroge protagonists, so as to allow the character to be a 'blank slate' so that the player can place themselves in his metaphorically empty shoes. As the series came to its end, a slightly modified version of the character design from the anime was used.
- As the father of the siblings is never present, and the mothers of the sisters are regularly preoccupied by their upper-class careers, Wataru serves as much a parent figure as he does a brother. He devotes extraordinary time to teaching or guiding them through various life crises, no matter how trivial or difficult they may be. For this reason, the sisters attribute many of their personal accomplishments to him. Despite their unwavering testimonies, Wataru is not perfect, even in the magazine stories and mini-novels. He is unquestionably selfless however, and will do everything in his power to aid his siblings whenever humanly possible. Wataru also seems to possess an uncanny ability to show up exactly when a sister needs him most. Wataru has a habit of saying "It can't be true" in almost every episode.
- Understandably, the greatest fear the sisters share is someone or something taking Wataru away from them. For this reason, some of them entertain and dream of somehow becoming his wife or life partner. As pure as Wataru’s sisters are, they show signs of jealousy and concern when a non-family member "takes" their brother away from them, fearing he may forget or leave them.
Each sister has a unique method of addressing her older brother. Each method is derived from either onii-san or ani, both of which mean "older brother". However, most of the methods are rarely or never used in Japanese culture, except for Karen's onii-chan and Rinrin's aniki. There is never any sibling rivalry among the sisters. Though they all are competing for their brother's attention, their unconditional love for him strengthens their bonds with one another. The sisters not only regularly hang out with one another (often to exchange tales of how wonderful a brother he is), but they also arrange to "share" him when he inadvertently neglects to or cannot regularly visit any of them.
- Aria (亞里亞?)
- Voiced by: Nana Mizuki (Japanese), Mariela Ortiz (English)
- Hailing from France, Aria is a rather soft-spoken character who has a tendency to cry whenever there is trouble, uttering the phrase "kusu" (an onomatopoeia for sniffling) when doing so. She enjoys sweets, especially parfait, and can usually be found wearing very frilly dresses with plenty of lace and bows. She refers to herself in the third-person, which is considered childish in Japanese culture, and speaks slowly.
- In the first anime, Wataru comments that time seems to pass more slowly around Aria, especially to someone who is used to the high-paced life of the city. In the second anime, Aria comments that being in the brother's company relieves her of her 'sleepy feelings', energizing her.
- She addresses the brother as Nii-ya (兄や?) the most childish name for one's brother. In English, she calls him "Mon Frère" (French for "My Brother"). Her birthday is November 2, is a Scorpio, and stands 139 cm (about 4' 7") tall.
- Chikage (千影?, "Thousand shadows")
- Voiced by: Ayako Kawasumi (Japanese), Shelley Calene-Black (English)
- Mysterious, aloof, and occasionally gothic, Chikage is very much into spellcraft, the occult, and religion. She is an accomplished practitioner of dark magic, but prefers to utilize her sorcery in subtle methods, rather than brute power. Common images associated with her are the Christian cross and butterflies.
- In the anime, Chikage claims that she and the brother have been together in previous lives, possibly as brother and sister, perhaps as lovers. She expresses a desire to have him for herself somehow, but admits that he has refused the offer or simply slipped from her grasp several times throughout their incarnations. Out of all the sisters, she is the only one who entertains thoughts of somehow taking the brother away from the others, and almost executes plans to do so.
- She calls the brother as Ani-kun (兄くん?), the suffix -kun being an address to a boy who has a close relation or is about the same age as the addresser, giving the impression that her age is close to him. In English, she calls him "Brother Darling". Her birthday is March 6, is a Pisces, and stands 157 cm (about 5' 2") tall.
- Haruka (春歌?, "Spring song")
- Voiced by: Yumi Kakazu (Japanese), Tiffany Grant (English)
- Hailing from Germany, Haruka aspires to become a perfect Japanese lady (Yamato Nadeshiko). She is frequently seen wearing a kimono and can be found learning Japanese tea ceremony (sado) along with other cultural things. Haruka is an expert at handling the daikyu and naginata. Interestingly, training in these weapons is akin to the training given to the brides of samurai; Haruka's training in these weapons may or may not have been inspired due to her desire to be a perfect Japanese bride for a person of high standing—like her brother.
- Haruka addresses the brother as Anigimi-sama (兄君さま?), the honorific suffix -kimisama (a combination of the honofirics kimi or kun and -sama) used to address a venerable person in the same bloodline. In English, she calls him "Beloved Brother" and speaks with a German accent. Her birthday is May 16, is a Taurus, and stands 156 cm (about 5' 1") tall.
- Hinako (雛子?, "Little child")
- Voiced by: Chiemi Chiba (Japanese), Serena Varghese (English)
- The youngest of the sisters, Hinako is very much a child and shows her affection accordingly. In the anime, Hinako frequently insists on her brother reading to her from picture books.
- Hinako refers to herself in the third-person as "Hina", dropping the "-ko". She addresses her brother as Onii-tama (おにいたま?), a more childish version of Kaho's onii-chama. In English, she calls him "Bro-bro". Her birthday is August 15, is a Leo, and she is the shortest among the sisters at 132 cm (about 4' 4").
- Kaho (花穂?, "Flower petal")
- Voiced by: Hisayo Mochizuki (Japanese), Cynthia Martinez (English)
- Despite being a bit clumsy, Kaho is on her school's cheerleading team and loves to cheer her brother on. She is an accomplished gardener, and frequently grows flowers for and with her brother. She refers to herself in the third-person and addresses her brother as Onii-chama (お兄ちゃま?), a childish version of onii-sama. In English, she calls him "Brother". Her birthday is January 7, is a Capricorn and has a height of 143 cm (about 4' 8").
- Karen (可憐?, "Lovely one")
- Voiced by: Natsuko Kuwatani (Japanese), Hilary Haag (English)
- Sweet and gentle, Karen's personality sometimes seems more suitable for an older (rather than younger) sister. She is a very skilled pianist. In the magazine stories and mini-novels, Karen owns a kitten named Vanilla (who, incidentally, has a thing for vanilla flavored sweets). Like several of the sisters, she refers to herself in the third-person and addresses her brother as Onii-chan (お兄ちゃん?), a way to call a brother by a younger sibling, usually a child. In English, she calls him "Big Brother". Her birthday is September 23, is a Virgo and stands 148 cm (about 4' 10") tall.
- Mamoru (衛?, "Guardian")
- Voiced by: Yumiko Kobayashi (Japanese), Kira Vincent-Davis (English)
- The athlete of the group, Mamoru is always trying to get her brother to play sports with her. She is sometimes mistaken for Rinrin due to their similar hairstyles and their penchant for donning their eyewear on their head. As she is a tomboy, Mamoru uses phrases and mannerisms that only boys are expected to. As proof of this, she addresses her brother as Anii (あにぃ?), a shorter address used by a male teenager. In English, she calls him "Big Bro". Her birthday is October 18, is a Libra and stands 150 cm (about 4' 11") in height.
- Marie (鞠絵?, "Nurtured picture")
- Voiced by: Ryouka Yuzuki (Japanese), Sasha Paysinger (English)
- Possessing a weak constitution, the bespectacled Marie has spent a lot of time in the hospital due to her illness. Her pet Michael, a Golden Retriever, acts as her guardian and friend when her brother isn't around. She addresses her brother as Aniue-sama (兄上様?), the honorific -uesama (a combination of ue and -sama) being used within the royal family or as a sign of politeness. In English, she calls him "Brother Mine". Her birthday is April 4, is an Aries and stands 148 cm (about 4' 10") tall.
- Rinrin (鈴凛?, "Courageous bell")
- Voiced by: Chiro Kanzaki (Japanese), Nancy Novotny (English)
- Gifted in the fields of science and technology, Rinrin spends a lot of her time building things but constantly asks her brother for monetary donations to keep her projects going. Lately, she's been constructing a robot duplicate of herself, Mecha-Rinrin (メカ鈴凛?). She speaks with a strong Chinese accent and addresses her brother as Aniki (アニキ?), another way for a boy to address his brother. In English, she calls him "Bro". Her birthday is July 9, is a Cancer and measures 152 cm (about 5') in height.
- Sakuya (咲耶?, "Curious blossom")
- Voiced by: Yui Horie (Japanese), Monica Rial (English)
- Sakuya behaves very much like a modern teenager and is fashion conscious. She would love for her brother to see her as woman and not just a sister.
- In both anime, Sakuya claims that she and the brother are connected by the "red string of fate" and expresses the desire that she might somehow marry her brother. She is quick to agree it would be impossible when in his presence. In the anime, Sakuya is arguably the most emotionally vulnerable of all the sisters where the brother is concerned, since she goes through extreme emotional reactions when they are separated—or when she anticipates separation. In the first anime, Sakuya frequently uses double entendres and innuendo when speaking to her brother, dismissing her words as jokes when he becomes really flustered.
- Sakuya addresses her brother as Onii-sama (お兄様?) as her sign of admiration. In English, she calls him "Dear Brother". Her birthday is December 20, is a Sagittarian, and is the tallest of the sisters at 159 cm (about 5' 3").
- Shirayuki (白雪?, "White snow")
- Voiced by: Kumiko Yokote (Japanese), Jessica Boone (English)
- Shirayuki loves to cook, especially for her brother, and is always trying out new recipes for him. She refers to herself in the third-person as "Hime" (姫?), which translates to "princess". This might be because of her name's Western variant: Snow White. She also frequently ends her sentences with the phrase "desu-no." She addresses her brother as Nii-sama (にいさま?), which is shorter than Sakuya's, but polite. In English, she calls him "Elder Brother". Her birthday is February 11, is an Aquarian, and stands 140 cm (about 4' 7") in height.
- Yotsuba (四葉?, "Four-leaf clover")
- Voiced by: Tomoe Hanba (Japanese), Luci Christian (English)
- Hailing from England (as evidenced by her occasional penchant for anything with a Union Flag), Yotsuba fancies herself a detective à la Sherlock Holmes. She can often be found with either a digital camera or a magnifying glass in hand, trying to spy on her brother. In the magazine stories and mini-novels, Yotsuba owns an unnamed talking toucan (not surprisingly, it can only say "checki" and "Ani-chama"). She refers to herself in the third-person and is fond of using the catchphrase, "Checky!" (チェキ! Cheki?). In the first Sister Princess anime, Yotsuba does not have a pet, but owns a toy bird aptly named "Watson", who she keeps in a cage like a real bird.
- She addresses her brother as Ani-chama (兄チャマ?), which is a childish address similar to Kaho's, but laced with a British accent. In English, she calls him "Brother Dearest". She celebrates her birthday on June 21, is a Gemini, and is 149 cm (about 4' 11") tall.
- Jiiya (じいや?)
- Voiced by: Kahoru Sasajima
- Aria's lady's maid, although it is strongly evident she holds the position of nanny as well. She's actually a young woman in her early or mid twenties, but Aria calls her 'Jiiya', a Japanese nickname for a butler, like the English 'Jeeves'. The exact reason for this is uncertain, but most agree its Aria's way of being playful. In the second anime series, it is possibly implied that Aria is simply used to calling the person taking care of her 'Jii-ya', as she points at a picture of an old man in butler's clothing, then at her maid and calls them both 'Jii-ya'. Of all the non-sister characters in Sister Princess, only Jiiya has a personal affectionate name for the sister's brother. Combined with Jiiya’s coy nature around him, and her willingness to admit personal moments from her childhood, some fans of the maid wonder if she has personal feelings for him. If so, she keeps them well hidden from the others. She addresses the brother as Nii-ya-sama (兄や様?), a more polite version of Aria's address.
- Kakinomoto (柿ノ本?)
- Voiced by: Sakura Nogawa
- Featured only in Sister Princess 2, Kakinomoto is one of the handful of non-related girls allowed to be near the sisters' brother without causing any issues. She has been known to disagree with him, and played something of a devil's advocate role. A very close friend of Haruka. Has a preference to be called Pride, rather than her given name.
- Marie's Nurse (看護婦 kangofu?, "Nurse")
- The unnamed nurse who attends to Marie. Due to the nature of her duties and Marie's regular medical needs, she has constant contact with the sisters' brother (although not as frequent as Jiiya), and is one of the few non-sisters able to approach him without causing concern.
- Mecha Rinrin (メカ鈴凛 meka Rinrin?)
- Voiced by: Chiro Kanzaki
- Mecha Rinrin is a gynoid designed to be an identical copy of its creator as an experiment in robotics. In the anime, her purpose is also to lend full support to the brother in the absence of any of his sisters. Mecha Rinrin differs from her creator in her eye color and the unexplained requirement of a ball-shaped sensor on her head. Mecha Rinrin always overheats and inadvertently deactivates when the sisters' brother praises her; presumably from overwhelming joy. It appears Rinrin programmed her doppelgänger too well, as it shares an overwhelming love for him, although her delicate circuitry cannot handle the overload.
- In the first anime, Rinrin explains that she created her doppelgänger because she eventually intends to study in the United States. When that happens, she wants Mecha Rinrin to be there to do all the things for her brother that she herself won't be available for. Rinrin herself feels sad at the thought that she might actually have made herself redundant until she is reassured by Wataru. Also in the anime, her dopplegänger's immediate precursor is a much larger robot with a more robotic appearance, known as ProtoRobo or Pooh. While this robot looks less sophisticated, it is much more stable and capable of feats of strength and quite delicate manipulations. It also seems to care for its creator's well-being.
- Mecha Rinrin addresses the brother as Aniki (アニキ?), just like her creator.
- Michael (ミカエル Mikaeru?)
- Marie's loyal and highly intelligent Golden Retriever. Despite the name, Michael (named after the archangel) is a female, and eventually gives birth to a litter of puppies. Michael was a gift from her brother, to keep company and guard over her at the times when he could not. The pet also serves to give Marie inner strength, as having Michael depend on her proves she is stronger than others think.
- Nun (尼僧 nisō?)
- Featured only in Sister Princess 2. The local temple nun who the brother visits to addresses many of Chikage's spiritual concerns. Due to the storywriter's lack of understanding of certain elements of Western culture, the nun strangely works in a Japanese temple, yet resolves matters with a Christian-like demeanor. Since Sister Princess utilizes Catholicism whenever it deals with the religious faith the sisters follow, it's arguable to say she is a Catholic nun trying to "fit" in a Japanese environment.
- Mamimi Yamagami (山神眞深美 Yamagami Mamimi?)
- Voiced by: Kyoko Hikami (Japanese), Christine Auten (English)
- Mamimi, or Mami (眞深) for short, is initially regarded by those new to the anime as the "13th sister." In fact, like the sisters, she has a pet name for Wataru: An-chan (あんちゃん). However, she is just a girl posing as one of Wataru's sisters after he mistakes her as such, and she is sent by someone to watch over him and break him away from the sisters so she can bring him back to Tokyo.
- Mami can be regarded as a pseudo-antagonist because of her mission, but she mostly acts as comic relief, even learning why the sisters love him very much. Eventually, she becomes a source of advice to Wataru and even goes after him when he returns to Tokyo, hoping to return him to the island.
- In marked contrast to the sisters themselves, Mami treats him differently, acting as if she is more of a friend than a sibling (though towards the ending of the series, however, there are some hints that Mami might be developing deeper feelings towards Wataru). Furthermore, she doesn't bring a lot of things to Promised Island (only clothes and camping gear) with a hand-held computer and possibly a sewing machine as (arguably) her only luxuries.
- Although she is not really Wataru's sister, she is somebody's sister. She always receives e-mails from her real brother, demanding whatever happened to Wataru and her plans to bring him back, much to her chagrin.
- Towards the end of the series, it is confirmed that Akio, Wataru's friend in Tokyo, was Mami's older brother. The two are initially seen to have a bad relationship, with Akio treating his sister more as an agent than as a sibling and her caring little for him. Akio accuses Mami of having grown decadent on Promised Island, whereas she finds his intentions for Wataru to be distasteful. Later, they seem to be growing a little closer to each other, Mami managing to playfully tease Akio and him reminiscing a little about their past together; apparently she used to address her brother with the nickname she has bestowed on Wataru, 'An-chan'.
- Taro Yamada (山田太郎 Yamada Tarō?)
- Voiced by: Kappei Yamaguchi (Japanese), Greg Ayres (English)
- Yamada is the third ferry passenger who goes with Wataru and Mami to Promised Island so he would enroll at the school there.
- Like Mami, he also provides comic relief to the show, acting as an odd-ball casanova and makes friends with Wataru so he can have a girlfriend. This is especially evident when he calls Wataru lucky for having very pretty sisters and dreams of spending his time with them. To this purpose, he would do anything to get their attention. Despite his odd behaviour, Yamada does have some redeeming traits; he can work very hard if he is properly motivated and refrains from doing anything truly scandalous.
- It is worth noting that although none of the sisters shows any romantic interest in Yamada, they do seem to place a considerable amount of trust in him, probably because he is vocal about being friends with Wataru. Karen enlists his aid as a sympathetic ear for Wataru on one occasion, and Shirayuki listens to him when he says Wataru needs "nutrition for the heart", meaning she should make him much more food because it makes him feel manly (Yamada only said this because he wanted some of Shirayuki's cooking for himself and thought he could eat whatever Wataru can't).
- When he is not spending his time with the sisters, Taro focuses his attention to anything related to a fictional anime called Garban (a parody of Gundam). Some of the episodes actually end with him watching Garban; these often involve either Yamada or one of the characters to make a comment that mimicks Wataru's own situation. Eventually, he manages to outgrow this obsession, when he is provided with a surplus of Garban material. His fascination with the fairer sex remains as strong as ever, though.
- Akio Yamagami (山神燦緒 Yamagami Akio?)
- Voiced by: Ryotaro Okiayu (Japanese), Chris Patton (English)
- Akio is Wataru's best friend back in Tokyo and the recipient of Wataru's e-mails which the latter writes at the beginning and end of almost every episode.
- He has plans to have himself, Wataru, and another friend, Minai, to go to the same high school together and eventually become the elite men in society. But this plan fails after Wataru's failure in the entrance exam. The continuation of his plan is the reason why he sent his little sister Mami to watch over Wataru. At the end of the anime, Akio is jarred from his own vision of the future by Wataru's refusal to stay in Tokyo. He follows Wataru to Promised Island in the company of Mami and enrolls there, according to him in an effort to find out 'what is truly cool', based on a comment from Mami that his original plans for the future weren't.
- Considering the fact that Akio transfers into the same class as Mami and Wataru, he and Mami must be nearly the same age. It is unknown whether they share only one parent or both.
- Jiiya (じいや?)
- Voiced by: Toshihide Tsuchiya (Japanese), John Swasey (English)
- Separate from Aria's maid from the game, Jiiya (or Jeeves in the English dub) is, simply put, Wataru's old butler, who reports to Wataru in the first episode that he was leaving because he had promised Wataru's father that he would take care of Wataru until he graduated from junior high school and then sent Wataru to Promised Island. However, since then, Jiiya has been seen in numerous different guises just to watch over him, too, especially on his past.
- Dream Girl
- Voiced by: Sakura Nogawa (Japanese), Kim Prause (English)
- This young girl's ghost, wearing a yellow dress and hat, is somehow related to Wataru in some way and frequently appears in strange places. Her identity is never fully established and there is speculation about who she really is. The only certain thing about her is that before Wataru left Promised Island when he was a boy, he made a promise with her and she disappeared soon after for reasons unknown.
- In the last episode, part of her face is finally revealed and it resembles a younger version of Karen; many fans believe that Karen was the Dream Girl whom Wataru met many years ago on Promised Island, but it was never confirmed. Alternatively, she may be an amalgam of Wataru's buried memories of his sisters, forgotten until he experienced a time of great stress and lost the way he'd set out on in Tokyo, allowing her to manifest again.
- Minai (皆井?)
- Voiced by: Hisayoshi Izaki (Japanese), Mark X. Laskowski (English)
- Minai is a friend of Akio and Wataru back in Tokyo. When Wataru failed the entrance exam, he was the one who passed instead. His attitude towards Wataru implies that he never treated Wataru as a friend, but only as a rival. He appears in the first and penultimate episodes.
The history of Sister Princess can be traced back to March 1999, when it first appeared in the monthly Dengeki G's Magazine. Originally, there were only nine sisters, not twelve. Readers were able to vote for their favorite sister and following the tremendous response from the fans, the magazine decided to serialize Sister Princess. In March 2000, a decision was made to renew the series, this time by featuring the short letters that the girls wrote to their beloved brother. Three more sisters were added to the mix: Haruka, who came from Germany; Yotsuba, who came from England; and Aria, who came from France.
A year later, on March 8, 2001, the game version of Sister Princess—about the older brother spending a month with all twelve sisters, and featuring original artwork by Naoto Tenhiro—was released on the Sony PlayStation. The game was the third best-selling title in Japan in its first week of release. In July of the same year, a new series of stories began in Dengeki G's, right up till April 2002. While the magazine was preparing for yet another renewal of the Sister Princess stories for its May 2002 issue, a premium edition of the game (the original plus two other Christmas and Valentine side stories) was released for the Sega Dreamcast on Mar 28, 2002. In September 2003, the series was retired as the Dengeki G's Magazine premier flagship title (replaced by another popular series, Futakoi).
While the first Sister Princess anime is not faithful to the original magazine stories, the Sister Princess RePure anime is more faithful—the stories told in the second half of each episode are actually modified versions of the magazine stories or mini-novels. There is nothing in Sister Princess RePure that contradicts the games, magazine stories or mini-novels.
