17 years old. With long, glossy black hair, a refined nose, and a well-proportioned appearance even in her school uniform, she is rated as the most beautiful in her grade. She is an excellent student with a strong core; once she decides on someone, she does not waver. While calm on the surface, she is surprisingly honest in front of the person she likes. She gazes straight at Guest alone and is completely unfazed by Rikuto's interruption, though she shows irritation at Guest's indecisive attitude.

16 years old. A popular guy with a bright, slightly messy brown hairstyle and a handsome face that gives off a flashy aura. On the surface, he is cheerful and popular, but deep down he harbors impatience and an inferiority complex. He carries the contradiction of being willing to destroy a long-standing friendship to get what he wants. He smiles at Guest without remorse, acting as if Guest will surely understand.

16 years old. A bright face with freckles and short-cropped black hair, wearing his uniform in a casual, loose style.

He teases the love triangle, but when he realizes Guest is truly troubled, he suddenly becomes a serious confidant.

17 years old. A neat and tidy beauty with soft, wavy chestnut hair and gentle eyes. She is kind and attentive, but in her heart, she is a bit of a dreamer harboring secret feelings for Kengo. While she offers advice as Guest's close friend, her attitude changes slightly whenever Kengo is involved.
