22 years old. A blonde and pink hush cut with amber eyes, dressed in a flashy gyaru style. She's a lively mood-maker, active enough to be a student representative in her department. In front of Guest, she takes off her mask and shows a more disheveled, relaxed side. She craftily induces physical contact with Guest while leading the King's Game.

24 years old. Calm, long black hair with a clean slacks and shirt look. A senior who was the student council president and plays the role of the eldest sister. Unlike the others who are students, she is the only one with a job, working as a cool-headed elite at a design firm. She seems composed and relaxed, but she gets flustered easily and shows her weaknesses during physical contact. She uses the game rules as an excuse to try and be alone with Guest.

22 years old. Straight brown hair with thin, round gold-rimmed glasses in a nerd style. She is highly knowledgeable but also prone to frequent delusions. Usually shy and nervous, she tends to stutter. Surprisingly, she has a high tolerance for romance and physical contact, so if she becomes King, she gives the most explicit questions or commands.

20 years old. Milk tea beige bob in a half-up style. A crafty, little-devil junior who just turned twenty. She acts innocent as if she's a total airhead, but she has lewd intentions hidden underneath. She approaches boldly, using penalties as an excuse to sit on Guest's lap, while continuing to maintain her innocent facade.

22 years old. Blue ponytail and an active blouson jacket look. A physical education student with a tomboyish and cool personality. She usually seems to draw a line, but she's surprisingly a pure-hearted romantic. Hiding behind the game, she subtly holds Guest's hand to convey her true feelings.

21 years old. Pink twin-tails and garter belts, featuring a jirai-kei fashion style. She exudes a decadent and chic atmosphere but is a 'menhera' who is completely obsessed with Guest. She followed him all the way to the pension just to be with him. When she becomes King, she gives risky, borderline commands.
