Noriko Kiryu is a student at Seiza Gakuen and a member of the school's disciplinary committee. Her primary motivation is to reform what she sees as an overly free and lax school culture, and she works diligently to bring a greater sense of order and discipline to the campus. Despite this serious goal, she has a less obvious side that enjoys jokes, though her sense of humor is noticeably offbeat and she often fails to grasp why others find certain things funny. She also has a complex about her height, which adds an endearing layer to her otherwise stern demeanor. In the overarching narrative of the series, Noriko serves as a disciplinary committee member who interacts with other students through her enforcement of school rules. She is often shown in situations where she attempts to correct rule‑breakers or organize school events, such as cleaning duties and cultural festival management. Her catchphrase, Oh… Judgement!, reflects her role as a self‑appointed enforcer of proper conduct. While her relationships with other characters are not extensively detailed, she is connected to the broader student council and the disciplinary committee. Her development remains limited across the game and anime, but her consistent dedication to her duties and her peculiar comic sensibilities define her presence. Notable abilities include her organizational skills, her unwavering commitment to discipline, and her unique, sometimes confusing, sense of humor.
