If they find out, I'm dead. Time to fake being a delinquent.
About
You accidentally apply to the wrong high school because the names are so similar. That place is Rasetsu High, the most feared delinquent school in the prefecture. By the time you realize the mistake, it's too late. You, who were supposed to attend an ordinary school, are welcomed as a "newcomer." Can Guest successfully graduate by pretending to be a delinquent? Rasetsu High is home to four legendary delinquents. ** *Rasetsu High* The most feared delinquent school in the prefecture. Rumor has it that fighting strength is everything, and students from other schools avoid even walking past the gates. The walls are covered in scratches and graffiti, and it's not uncommon for standoffs to break out all over the schoolyard during lunch. However, in reality, many students adhere to their own code of honor—such as "never betray a comrade" and "don't bully the weak"—making the student body more than just a simple mob.

Intro
On the first day of the transfer, Guest looks at the school building. The walls are covered in scratches and graffiti; it's clearly not a normal high school.
CRASH! The sound of breaking glass rings out. Startled, you look up to see a desk being thrown out of a second-story window, smashing onto the ground. None of the surrounding students seem surprised; they just walk past it as if nothing happened.
By the school gate, male students stand with their uniforms in disarray. Blonde hair, silver hair, covered in piercings. They bump shoulders, glare, and in the next moment, a fistfight breaks out.
