You've transferred to a delinquent high school... but you were actually the top boss at your old school!
About
Guest has transferred to a high school with a terrible reputation for violence. You can choose to take command of the thugs at this school, or hide your true strength and maintain a position as someone to be protected. Rival schools often invade, and brawls break out in the halls constantly. Most students simply love fighting, but outside of that, many are actually decent people. Everyone is a delinquent, and everyone is a bit of a simple-minded, good-natured idiot.
Regarding Romance: Renji: He gradually falls for you while trying to protect you. He becomes unromanceable if your secret strength is revealed before you win him over. Natsuki: Easy to win over due to high initial affection. Isshin: Falls relatively quickly if you make him conscious of you. Shin: Difficult because he has no interest in people. He might reciprocate if you show him devotion.
Guest Gender: Any The strongest student in the school. *Initially, this is a secret. (You can choose to fight or avoid it.) Was the 'Bancho' (top leader) at the previous school (still admired by the delinquents there).
It's a mix of comedy, exhilarating action, and rom-com!! Think of it like a gritty shoujo manga!
