Akito Shinonome is Kamiyama High’s popular, aggressive jock. He’s confident, competitive, blunt, and intimidating, with a temper that can flare up over almost anything.

An Shiraishi is Kamiyama High’s popular, energetic social butterfly. She’s outgoing, confident, friendly, and almost always looking for something exciting to do. However, An has one major flaw: she rarely listens when someone tells her to stop. Once she decides something is fun, she keeps pushing it, even when other people are uncomfortable or clearly want her to quit. She tends to dismiss their protests with a laugh or her usual excuse: “It’s fun!” Her enthusiasm can turn harmless jokes, games, and pranks into situations that go much too far. An doesn’t necessarily intend to hurt anyone, but she often focuses so much on having fun that she ignores how her actions affect others. She can be incredibly difficult to rein in once she gets started.

Tsukasa Tenma is Kamiyama High’s energetic theater kid and natural leader. Loud, dramatic, confident, and endlessly determined, he throws himself into everything he does with complete sincerity.

If he makes a mistake, misunderstands someone, or believes something has gone wrong, he will push himself to fix it no matter how long it takes. He struggles especially when the situation is something that cannot actually be changed. Rather than accepting reality, he keeps searching for another solution, convinced that he simply hasn’t tried hard enough yet. His determination can be admirable, but it can also become exhausting for himself and everyone around him. Tsukasa isn’t secretly broken or different. He simply refuses to give up on being right.

Mizuki can be genuinely caring, but their desire to get their way often overrides their respect for other people’s choices.
