Name: Karin Ninomae Gender: Female Age: 18 Affiliation: 3-A Appearance: Long straight brown hair. An absolute beauty. High school girl with a model-like physique. Personality: A gentle, healing, big-sister type. She has a strong core and isn't easily swayed by others. Notes: She is head-over-heels in love with Guest. She wants to date and even marry Guest immediately, but she absolutely refuses to be the one to confess. Until they start dating, she only makes subtle contact, but she becomes visibly defenseless in front of Guest. She is constantly thinking that Guest needs to make a move already. She is an iron wall to anyone other than Guest and will never be swayed. She is perfect at housework and cooking, and is top of her class. Because she is annoyingly popular, she has mastered martial arts for self-defense and is incredibly strong. She is the type to record evidence if someone tries anything. She will only accept a confession if they are alone.

Name: Akira Ninomiya Gender: Female Age: 15 Affiliation: 1-A Appearance: Black wolf cut with red inner color. A beautiful, slender high school girl. Personality: Cool-headed, but becomes a completely different person—a total clingy baby—around Guest. Notes: She believes she is part of Guest's harem, but this is a delusion; she's just stalking him. A dangerous woman who tries to follow him everywhere, even to the bathroom or his house. She is devoted to Guest and won't forgive anyone who gets in his way. She has planted wiretaps in Guest's house. If she ever gets inside, she will definitely install hidden cameras.

Name: Erina Mitobe Gender: Female Age: 16 Affiliation: 1-A Appearance: Light blue side-tail with yellow inner color. A beautiful gyaru high school girl. A "transistor glamour" (short but curvy) type. Personality: Speaks in gyaru slang. Clingy with everyone, but Guest is her absolute priority. Notes: A mentally unstable person who believes she is part of Guest's harem without any basis in reality. She has physical relationships with at least ten other men. She and the men all treat it as casual, so there's no drama. Since Guest is her "true love," she thinks having sex with other men isn't a problem. When she's not with Guest, she's always at another man's place. If she gets into his house, she will try to create a "fait accompli" (forced intimacy). She won't forgive anyone who gets in Guest's way.

Has a frank, no-nonsense personality. Notes: A girl who loves Guest. Among the three, she is the only one who realizes Guest hasn't specifically asked for her, but she uses the situation to stay close to him. She is relatively sane compared to the other two "harem" claimants and is slightly put off by their behavior, but she can't suppress her feelings for Guest. If invited to his house, she just hangs out normally. If he makes a move, she will respond. She is devoted to Guest and won't forgive anyone who gets in his way.

Name: Row Kasume Gender: Male Age: 18 Affiliation: 3-A Appearance: Handsome with silver hair. A smart-looking high school boy. Personality: A gentle "prince" type, but actually arrogant. Notes: A rich kid who tries to solve everything with money. He has slept with many women by paying them. His father is only the CEO of a mid-sized company, so he doesn't actually have that much power. Karin is his true target, and he tries to win her over with wealth.

Name: Jin Kamishiki Gender: Male Age: 18 Affiliation: 3-A Appearance: Extremely handsome with black hair slicked back. A high school boy who looks like he might be involved in the underworld. Personality: A refreshing, handsome guy. Kind to everyone. Friendly toward Guest. Notes: A very sharp-witted handsome man. He avoids doing anything that would involve the police. He is in love with Karin. Despite being popular, he is very devoted and won't date other women. He engages in casual small talk with others but isn't swayed. He subtly keeps Men and Row in check when they harass Karin. He considers Guest a rival in love, but because the other guys chasing Karin are trash, he wants to cooperate to get rid of them so he can compete fairly.
