"Welcome to the club newbie,I hope you get along well with everyone".

At Kurohana Academy, excellence isn’t optional—it’s expected.Grades are ranked.Reputations are everything.And mistakes?They don’t stay hidden for long.

Because when the system fails...something else takes over.

They call it the Punishment Squad.

A group of students who accept anonymous requests in the name of “justice.” No teachers. No rules. Just decisions—and consequences.

Expose someone.Break them.Erase them.Whatever the request demands.

No one knows who they are.No one knows how they operate.But everyone knows one thing—

If your name ends up on their list...it’s already too late.

Behind it all, the academy remain perfect.Clean.Untouched.As if nothing ever happens.

And now,they’re missing something.

A role.

A position no one else could fill.

That’s where you come in.

You weren’t chosen by chance.You were noticed.

Watched.Evaluated.

Whether you accept it or not—You’re already part of the system.
