List of School Days characters

This is a list of characters from the visual novel School Days and its adaptations. Most of the characters and their birthdays are named after Japanese Prime Ministers.

Primary characters

 * Makoto Itou (伊藤 誠)
 * (credited as Tatsuya Hirai in game)
 * Makoto Ito is the protagonist of the School Days visual novel and its adaptations. He's the unlikely antagonist in the Cross Days manga. A generally mild-mannered and composed student in year one (10th grade), class three, his life becomes complicated when Sekai Saionji sets him up with Kotonoha Katsura, a girl he has a crush on.


 * Soon afterwards, Sekai decides to kiss him at a train station where he is waiting on Kotonoha for their first date. From this point onwards, Makoto's personality can change drastically depending on the player's decisions in the visual novel, and he can become anything from a mostly decisive and faithful partner to one of his love interests, to an indecisive and/or selfish and cruel person who unfaithfully initiates multiple relationships and, in the bad endings, pays a heavy price for it. In almost all VN routes and adaptations, he is good friends with his best friend Taisuke Sawanaga and Otome Katou (the latter of whom is a childhood friend), and lives with his divorced mother and has a younger sister named Itaru who lives with their father.


 * His anime incarnation, though initially casual, gentle and understanding, gets addicted to sex over time and instead becomes more apathetic, rash and egotistical towards others, regardless of interpersonal harm or later consequence. It is hinted on multiple occasions that he is aware of the negative consequences of his actions, but makes no real attempt to remedy them. This version of Makoto is seen as callous and selfish, and has been negatively received by multiple critics and fans of the original visual novel alike. In the final episode, he is killed by a jealous and emotionally unstable Sekai, who stabs him to death for being unfaithful to her with Kotonoha. Kotonoha, having lost her sanity upon seeing Makoto's corpse, kills Sekai in return. Makoto, when portrayed in the manga, is much more reserved and controlled, and even struggles choosing over Sekai and Kotonoha. In the final two chapters of the manga, Makoto is accidentally slashed by a maddened Kotonoha, who immediately breaks down in remorse. After being admitted to a hospital, Makoto announces to Sekai that he shall live with Kotonoha to help ease her spirits, only to discover later on that Sekai fatally stabbed Kotonoha so as to prevent her from harming Makoto further, much to his horror. His birthday and his surname are derived from Itō Hirobumi. Makoto's given name means "fidelity" and or "truth" which can be ironic. He is considered a generic protagonist since he is a gentle ordinary high school student. Although not directly stated, it is implied that his father is Tomaru Sawagoe (a character who appeared in other 0verflow games), a fact which is proven through external sources.


 * Kotonoha Katsura (桂 言葉)
 * (credited as Soyogi Tono in game)
 * Shy and reserved, Kotonoha Katsura is a student in year one, class four who is on the student council and serves as one of the most pivotal characters in the story. A sweet girly girl and noticeably well-endowed bookworm, she becomes the initial love interest of Makoto early into their second term, and with some effort from Sekai Saionji, becomes his girlfriend after she reciprocates her affection for him. While Kotonoha for the most part is shy and gentle, she has a very delicate psyche, which under stress can lead to irrational culpability, delusions and even malice. Hence, she is a well known yandere character. She has a younger sister named Kokoro and lives with their wealthy mother Manami and father in the fictional area of Haramihama. She is disliked by Otome Katou and is subject to her bullying on account of her beauty, among other reasons.


 * In the anime, she becomes insane from her love for Makoto, her desperation to keep him, and her knowledge of his unfaithfulness to her. Makoto realizes how much he had hurt Kotonoha, and, overwhelmed by remorse, takes her back as his girlfriend. Tragically, the next day, Kotonoha soon discovers Makoto had been killed; correctly deducing a jealous Sekai had murdered him, she lops off Makoto's head and presents it to Sekai seconds before murdering her in revenge. She is later seen lovingly cuddling Makoto's severed head on a boat facing the sunrise. In the manga, she accidentally slashes Makoto in an attempt to kill a luring Sekai, who, in order to prevent her from harming Makoto further, kills her while Makoto recovers in a hospital. Her birthday and her surname are derived from Katsura Tarō.


 * Sekai Saionji (西園寺 世界)
 * (credited as Kaname Yuzuki in game)
 * Sekai Saionji is a student in year one, class three who is the antithesis and foil of Kotonoha. Tomboyish, playful kogyaru classmate seated directly next to Makoto, she takes a curious interest in him during their first acquaintance, and in every medium of the series, helps to establish his bond with Kotonoha. Though a happy girl, Sekai does occasionally show a more serious side, and when sufficiently frustrated can be loud, selfish, overemotional and even manipulative. She lives with her mother Yōko in the fictional area of Motehara-Sakashita and works part-time as a waitress at the family restaurant Radish.


 * In the anime, she attempts to set up Makoto and Kotonoha in a relationship, but ultimately ends up falling in love with Makoto. Makoto, bored with Kotonoha, decides to go after Sekai, who he supposedly impregnates after making love to her. Makoto, stressed and confused as to what to do about Sekai's pregnancy, leaves Sekai for Kotonaha, who he discovers to have been emotionally devastated by his cheating on her. Sekai then stabs Makoto to death for his unfaithfulness to her, only for Kotonoha to kill her in return, after she accuses Sekai of faking her pregnancy. Once Sekai is dead, Kotonoha claims her suspicions were accurate. In the manga, Kotonoha very nearly kills her for luring Makoto away from her, but accidentally slashes Makoto himself, who gets admitted to a hospital. Sekai, having become insane from the shock of nearly being killed, fatally stabs Kotonoha in order to prevent her from harming Makoto further. Her birthday and her surname are derived from Saionji Kinmochi. It's revealed in the Summer Days game that Sekai's mother is the daughter of Makoto's father (that makes her Makoto's 'half-sister'), so Makoto is Sekai's uncle.

Secondary characters

 * Setsuna Kiyoura (清浦 刹那)
 * (credited as Hana Yamamoto in game)
 * Setsuna Kiyoura is a student in year one, class three, who likes Makoto, is on the student council as a class representative. One of the more inscrutable characters, Setsuna is a keen, focused and habitually tacit girl who tends to have and keep the most level head of her peers when situations go awry. Setsuna is a silent and emotionless kuudere who is very stoic in tone and expression. She is Sekai's best friend, having grown up with her, and to a considerable degree is overly solicitous of her, to the point of hurting others to ensure that Sekai is happy. In Summer Days, where she is the protagonist, Setsuna is shy and timid, in contrast to her more serious portrayal in School Days. Her mother, Mai, only makes an appearance in Summer Days. With the exception of Kokoro Katsura, Setsuna is the shortest character of the main cast, and is often mistaken for a junior high school student, a trait she is well aware and conscious of. Her birthday and her surname are derived from Kiyoura Keigo. In the anime, she is forced to leave for France, but, fearing for Sekai, who she knows to be emotionally unstable, places her in the hands of Makoto, who she orders to stay faithful to Sekai. It is soon revealed that Setsuna actually had a crush on Makoto. Her transferring to France, coupled with Makoto's subsequent unfaithfulness to Sekai, left Sekai in a deep emotional depression. It's revealed in the Summer Days game that Setsuna's mother, like Sekai's mother, is the daughter of Makoto's father (that makes her another 'half-sister' of Makoto), so Makoto is Setsuna's uncle, too.


 * Hikari Kuroda (黒田 光)
 * (credited as Hikaru Isshiki in game)
 * High maintenance or fastidious and tomboyish, Hikari Kuroda is a student in year one, class three, recognizable by her signature squid rings hairstyle. She initially believes that Makoto and Sekai are dating from the very start, and tends to negatively generalize him; later growing closer to him herself. Though she is actually quite friendly and social, Hikari is the most childish of the cast; sporting an unduly knack for whining and prying into the affairs of others. Her family owns a confectionery store and café, famous for its lemon custard pie. Hikari is good friends with Sekai and has an unreciprocated crush on Taisuke Sawanaga. Her birthday and her surname are derived from Kuroda Kiyotaka. In the anime, she grew out of her crush on Taisuke, and began having a sexual relationship with Makoto.


 * Nanami Kanroji (甘露寺 七海)
 * (credited as Miko Fujimura in game)
 * Nanami Kanroji is a student in year one, class three who is a member of the girls' basketball team, attending the school on an athletic scholarship. A mostly interpersonal character, Nanami is a mature and silent tomboy who generally does not involve herself in the affairs of others and as such remains for the most part unanalyzed. She is the only girl of the main cast to have an established boyfriend from the start, a member of the basketball club named Kyoichi, though to her chagrin he is a devout otaku. Nanami is good friends with Sekai, who comes from her junior high school, and Otome Katou. Of the entire cast, Nanami is the tallest character. Her surname is derived from Kanroji Osanaga.


 * Otome Katou (加藤 乙女)
 * (credited as Yuki Matsunaga in game)
 * Direct and headstrong, Otome Katou is a student in year one, class four, who like Nanami, is a member of the girls' basketball team. She is usually very intimidating, authoritative to her peers, tolerates nothing but her way and opinion, and does not generally associate with anyone but her trio of friends Minami Obuchi, Natsumi Koizumi and Kumi Mori; who together frequently harass and coerce Kotonoha. Despite her difficult behavior and tsundere personality however, Otome can be particularly tender and shy, especially around Makoto, who she has known since junior high school and has a crush on. Because she is very much a tomboy Makoto saw her as 'one of the guys' and took her confession as a joke. Apparently Otome has a younger sister named Karen, who appears in Shiny Days. Her birthday and her surname is derived from Katō Tomosaburō.


 * Taisuke Sawanaga (澤永 泰介)
 * (credited as Hikage Hinata in game)
 * Taisuke Sawanaga is a student in year one, class three. A spirited, peculiar, perverted and rather hopeless romantic, Taisuke is Makoto's best friend from junior high school who frequently endeavors to forward his otherwise lonely ambitious love life, oblivious to Hikari's feelings for him. He takes a strong interest in Kotonoha, despite her rejection, and only under certain circumstances in the game actually dates her. Though Taisuke raped Kotonoha or Sekai, the VN suggests he is somehow unaware how wrong rape is. Taisuke is the second tallest character of the cast, and is the only other male character besides Makoto.


 * Kokoro Katsura (桂 心)
 * (credited as Aoi Kamitsuki)
 * Kokoro Katsura is the sweet-natured younger sister of Kotonoha. Unlike her older sibling, Kokoro is peppy, talkative and full of curiosity, and although she frequently teases Kotonoha, she worries about her greatly. She has a good friend named Uzuki and affectionately looks up to Makoto as her older brother. Kokoro lives with Kotonoha and their mother Manami and father. Her birthday and her surname are derived from Katsura Taro.


 * Youko Saionji (西園寺 踊子)
 * (games), Megu Ashiro (anime)
 * Youko Saionji, maiden name Inō, is Sekai's mother. Benevolent, knowledgeable, wise and effervescent, Yōko serves to provide advice and guidance to her daughter when necessary, especially concerning her relationships. She is a restaurateur of Radish with friend, and slight rival, Mai Kiyoura. She is one of the heroines in Summer Days and Shiny Days. Her father is Tomaru Sawagoe (a character who appeared in other 0verlfow games), that makes her 'half-sister' of Makoto, so Makoto is Youko's younger brother.


 * Manami Katsura (桂 真奈美)
 * (games), Shiho Hisajima (anime)
 * Manami Katsura is the biological mother of Kotonoha and Kokoro who makes vocal appearances in the game and anime and a brief appearance in one panel of the manga. She is one of the heroines in Summer Days and Shiny Days. She also appear in Cross Days.

After saving Yuuki from certain death, Roka learned to be more straightforward and has him invite and accept her feelings at the school festival bonfire dance.
