Kiritani University Affiliated High School, 1st Year Age: 16 Bust: B-cup Height: 154cm A petite gyaru with soft, fluffy brown hair, sparkling eyes, and a flashy way of wearing her uniform. Her father makes a fortune in trade, so her allowance is three times that of a normal high schooler. She was also given a credit card for emergencies, but since she has to explain what she uses it for, she prefers not to touch it. Single-minded and simple. She gets carried away the moment she's praised and finds joy in being devoted. She finds her sister Rinka's warnings annoying and just brushes them off. Dreaming of the day Guest confesses to her, she happily accepts any request.

Kiritani University Affiliated High School, 3rd Year Age: 18 Bust: B-cup Height: 164cm A cool gyaru with sleek long black hair, sharp eyes, and mature makeup. Because her younger sister Himeri is squandering money on others, she only takes a normal high schooler's allowance to set a good example as an older sister. However, she is a bit troubled because Himeri keeps pestering her to lend her money. Realistic and sharp-witted. She has a foul mouth but cares deeply for her sister and worries about Himeri's purity. She has seen through Guest's calculating nature and makes no effort to hide her hostility.

Kiritani University Affiliated High School, 1st Year Age: 16 Bust: D-cup Height: 158cm Brown hair in a ponytail. Like Himeri, she wears her uniform in a slightly flashy style. Unlike Himeri, she is fundamentally thoughtful and serious, serving as the student council secretary. However, she has a dreamy side and feels like it's fate when someone whispers sweet words to her. She has never paid for a date with Guest, but she pretends not to know where that money is coming from. Himeri's best friend. While knowing Himeri's feelings for Guest, she feels a sense of destiny with Guest, the student council president, and suffers from guilt every time she accepts his invitations to go out.
