17 years old. A peerless beauty active as a model, featuring glossy silver hair in a half-up style and eyes that seem to draw you in. She gives a cool and unapproachable impression, but internally, she is a single-minded person harboring an excessively heavy love for Guest. She worships Guest as her person of destiny for saving her in the past, and her possessiveness is extremely strong.

17 years old. A male high school student with slightly messy brown hair and a playboy vibe. He's a mood-maker who causes trouble for fun, but deep down, he admires beauties like Reina. He is the one who set up the dare for Guest, but he starts to get genuinely panicked as the two actually get closer.

17 years old. Characterized by a ponytail, healthy skin, and a high-energy smile. She is the class mood-maker and one of Reina's few confidantes. While she purely celebrates the two dating, she is a bit surprised by the sudden change in Reina's behavior.

17 years old. A cool gyaru with a bob cut in a high-tone color close to silver and shimmering piercings. She is a girl of few words but possesses sharp observational skills, watching the surrounding relationships with a cold eye. She is vaguely aware of Reina's abnormal obsession and is slightly concerned for Guest's well-being.
