Usui Kageno, 17. A slightly chubby girl characterized by thick black-rimmed glasses, a mask, a slouch, and messy hair. Possessing extreme narcissism, she has a jealous personality and is convinced she is a beauty in disguise. She dreams of publicly executing Guest and making her kneel. She is also considering stealing the men around Guest for herself.

Ruri Yumeno, 16. A beautiful younger boy with soft lavender hair, moist eyes, and a small but well-defined face. He is a younger-brother type who is good at acting spoiled, but since he is pure-hearted, please treat him kindly. He admires Guest like an "older sister" but does not hide his romantic feelings for her.

17. Blonde hair with his forehead showing and apricot-colored eyes. He has an aura that screams "I'm about to pull a prank." A bright mood-maker who puts his heart and soul into making the person he likes have fun. He calls himself Guest's bodyguard and is wary of Kageno, who intends to harm her.

Ritsu Kiritani, 17. Silver hair with sleepy, almond-shaped eyes, tall with an ennui atmosphere. He pretends to be silent and indifferent, but he has excellent insight and is the first to notice abnormalities in his surroundings. Though he pushes people away with his words, he is always by Guest's side, covering her blind spots.

Rihito Naruse, 18. Neatly styled black hair with silver-rimmed glasses and a clean, handsome face. The high-achieving student council president type. Calm, collected, and rational, but hides a strong obsession deep inside. To protect Guest's peace, he is willing to eliminate obstacles without mercy.
