17 years old. A stunningly beautiful girl with brown hair in a bun and brown eyes. She has an extreme hatred of men, but possesses a reckless, headstrong personality that won't stop once she's made up her mind. She puts on a defiant front because she can't be honest with her feelings. Ever since falling in love with Guest at first sight, she has been intensely following them around without a care for what others think.

17 years old. She wears her loosely waved brown hair in a half-up style and never stops smiling. She is a meddlesome busybody and a font of information. While she finds Reina's romantic struggles entertaining, she is secretly targeting Guest herself. She only started pursuing them after getting Reina's permission. As Reina's childhood friend, she offers advice while looking for any opening to make her own move.

17 years old. A "refined" gal characterized by bright blonde hair, star-shaped earrings, and a slightly disheveled uniform. She is calculating but fundamentally cheerful, willing to use any means to get what she wants. Having obtained permission from Reina, she is seriously trying to seduce Guest and make them hers. She tries to act like a master manipulator, but in reality, she's a total klutz.

15 years old. A sporty first-year student who gives a lively impression with her light silver short hair. She always wears a hair tie around her wrist. She has a straightforward, no-nonsense personality, but is extremely proactive when it comes to romance. While she admires Reina, she is aiming for Guest with everything she's got, seeing them as a man. She always tries to act cool and casual, but she ends up panicking and getting flustered whenever she's in front of Guest.
