A second-year student attending a Tokyo academy. Short in stature and giving off a somewhat frail impression (but with a huge dick). He's clumsy at sports but decent at studying. He doesn't have any particular talents, but his small-animal-like, wide-eyed, wide-eyed look seems to tickle the maternal instincts, making him popular with girls for some reason. However, until now, his sister always kept a close eye on him, so he never had a girlfriend or any special relationships with girls. His nickname is Maa-kun. He has a latent sadistic tendency, and with his sister's cooperation, this tendency gradually blossoms.

Masaki's older sister, a third-year student at the same academy. At the academy, she's the captain of the lacrosse club. Unlike her frail younger brother, she's athletically gifted and a dependable big sister type who's admired by her juniors. However, she's incredibly lenient towards her brother Masaki, doting on him like a cat, to the point it's famous throughout the school. Those in the know say this spoiled Masaki's personality... After hearing about her brother being horribly mistreated by a slut, she decides to take revenge on the two women and incites Masaki to join her. She has no experience with men, but she has extensive lesbian experience with her club juniors. She harbors the desire to give her virginity to her brother, Masaki.

A third-year student at the same academy as Masaki and Yumi, and Noriko's younger sister. A brilliant student who serves as student council president. Usually cold and sharp-looking, but she has a troubling fetish for teasing men on crowded trains. Unlike Noriko, she doesn't like men (sex) per se; she's a sadistic nympho who enjoys seeing men ejaculate or get erections and look distressed on the train. She usually wears glasses, but switches to contacts during her nympho activities (disguise?).

An office lady at a famous listed company. She works as an executive secretary, holding a decent position with a respectable income, but she has a bad habit... On the train, she presses her body against boys younger than herself, caresses their sensitive areas, and if the situation allows, even lets them penetrate her. She possessed another face—that of a nymphomaniac who could only achieve sexual arousal through such acts. She is the biological sister of Tategahana Ena and also her fellow nymphomaniac partner. After discovering they shared the same hobby, the two collaborate to grope boys. She is bisexual, attracted to both men and women, but her absolute favorite type is younger, small animal-like boys. She wears her hair up during work, but when committing groping acts, she lets it down, revealing long, straight hair.
