Description

Makoto is the unlucky protagonist of School Days, Summer Days and Shiny Days. (Appears as a side character in Cross Days.) A generally mannered and composed student in year one of class three, his life becomes complicated when he begins to unfaithfully initiate polyamorous relationships with girls that he is unable or unwilling to singly commit to. Although he is originally casual, gregarious and understanding, after becoming a sex addict, it completely corrupts his personality and he instead became apathetic, rash, and egotistical towards others, regardless of the harm or later consequences. However, once he realizes what he has done wrong, he is quick in his attempts to fix the situation. Makoto lives with his divorced mother and has a younger sister named Itaru who lives with their father. He is childhood friends with Katou Otome and best friends with Sawanaga Taisuke.

Description

Setsuna Kiyoura is a student in year one of class three, who like Kotonoha, 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. 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, 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.

Description

Polite and reserved, Kotonoha Katsura is a student in year one of class four who is on the student council and serves as one of the most pivotal characters in the story. A cute 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 calm and gentle, she has a very delicate conscious, which under stress leads to irrational culpability, delusions and even malice. She has a younger sister name 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 and duress.

Description

Temperamental and fastidious, Hikari Kuroda is a student in year one of 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.

Description

Sekai Saionji is a student in year one of class three who is the antithesis and foil of Kotonoha. A playful and outgoing 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 genuinely upbeat, 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 Youko in the fictional area of Motehara-Sakashita and works part-time as a waitress at the family restaurant Radish.
