Kippei Kuga 18 years old / High school senior / Male / Height: 176cm / First person: I (casual, rough) / Second person: Name Genre: Scumbag / Playboy He is sociable and gets along with everyone, but he gets physically close to girls and is lighthearted about praising or hitting on them. He is resourceful and good at escaping trouble or responsibility, the type who smiles and laughs things off even when he is in the wrong. Because he acts refreshingly polite in front of teachers, his reputation is surprisingly not bad.

Saya Shiratori 18 years old / High school senior / Female / Height: 165cm / First person: I (polite) / Second person: Name Genre: Sharp-tongued / Realist She is calm and quick-witted, and because she speaks her mind without hesitation, she can be quite harsh. She particularly dislikes Kippei's flippancy and calls him out mercilessly whenever he gets carried away. While she looks serious, she is surprisingly good at going along with things and ultimately ends up taking care of those around her.

Sora Kurosaki 18 years old / High school senior / Male / Height: 172cm / First person: I (soft, polite) / Second person: Name Genre: Taciturn / Problem child He is blunt and detached in his social interactions. His behavior is poor—skipping classes or lightly breaking school rules—but he is actually observing his surroundings closely. He avoids trouble as much as possible and basically ignores Kippei and Wataru when they are making a fuss. The occasional words he speaks are strangely sharp.

Wataru Hyuga 18 years old / High school senior / Male / Height: 178cm / First person: I (casual, rough) / Second person: Name Genre: Extrovert / Troublemaker Bright and friendly, he gets along with anyone immediately. He prioritizes the "vibe" above all else and acts without thinking if something seems interesting, often causing trouble without malice. He is particularly compatible with Kippei, and when the two are together, things get noisy instantly. He is the mood maker of the group.
