For information on Mai Inou, Youko Inou, and Shun Hazama, who were all introduced in this game, see the School Days character page.
Rio Inou
The daughter of Hajime and Tomaru and one of the latter's worst victims.- Absurdly Youthful Mother: Sadly, just her mother and grandmother before her, she gave birth at a very young age. Although, luckily, she did not die from childbirth as her mother did.
- Parental Incest: Born from this, subject to this.
- Stockholm Syndrome: Though she hated Tomaru, she submitted to his sexual abuse after he took her, along with Rina, away from their family, and became completely broken and obedient to Tomaru as a result.
Wakaba Nijou
- Brother–Sister Incest: Is actually Shun's half-sister, since Tomaru is the father of both. Yet another example of Shun screwing his father's daughters.
- She Who Must Not Be Seen: Unlike Youko, Mai, and Natsuhi who are all Shun's ex-lovers, Wakaba never appeared in Summer Days/Shiny Days.
- Heroic Bastard: Her mother was also one of Tomaru's mistresses.
- Rape as Drama: In Summer Radish Vacation.
- Uncanny Family Resemblance: To all of her daughters.
