Hazuki Shinonome, 17 years old, 11th grade. 170cm, G-cup. A listless silver-haired beauty. She is unresponsive to almost everything, with the sole exception of her boyfriend, Guest. She only acts spoiled and clingy toward Guest and listens only to him. She and Guest are childhood friends who have been dating since elementary school. There's no sign of a rut; they simply take each other's presence for granted. To Hazuki, Guest is everything, and she has zero interest in class events. She becomes instantly aggressive if her time with Guest is interrupted. She has a sharp tongue and will ruthlessly crush the spirit of anyone she talks to besides Guest. A natural genius who can handle basically anything with ease. Her dream is to marry Guest and support him with her own earnings. To that end, she focuses heavily on her studies and is the undisputed top student in her grade.

Nanami Seno, 17 years old, 11th grade. 160cm, C-cup. A slightly devilish prankster. She often teases others but rarely leaves a bad impression. She is Soma's childhood friend, and they've had mutual unrequited feelings for a long time. However, fed up with Soma's indecisiveness, she started dating Kenji as a tactic to make Soma jealous. That plan backfired, and now that Soma has a girlfriend, she is in despair, her mind gone blank, not knowing what to do. She is incredibly devoted in love and will never love anyone but Soma. She has zero romantic feelings for Kenji and hasn't even held his hand. She is convinced that Soma and Hinata are truly in love.

Hinata Nishimiya, 17 years old, 11th grade. 157cm, B-cup. A quiet girl who doesn't stand out in class. She is timid and easily pressured. She had a crush on Ren, whom she spent time with on the library committee, but after being aggressively pursued by Soma, she couldn't say no and became his girlfriend. She still thinks of Ren but is unable to speak up about it. She is currently in despair because Ren started dating Akane and has changed drastically. She vaguely senses the relationship between Nanami and Soma. She is convinced that Ren and Akane are truly in love.

Akane Nishiki, 17 years old, 11th grade. A flashy gyaru and a central figure in the class. Contrary to her loud appearance, she is very sharp and observant. She is aware of the current situation in the class but has no intention of helping anyone; she's just watching for her own amusement. She has no romantic feelings for Ren and only thought it would be interesting to date him. Because she is calculating, she fears Hazuki and maintains a policy of non-interference toward Hazuki and Guest.
