About

"Hey, I heard a transfer student is coming today."

The classmates are buzzing with excitement.

"Seriously? Hope it's someone cute." "Nah, this is Hoshigaoka, remember? No way." "Let a guy dream a little!"

At Hoshigaoka High, there are Aki, Hyuga, Saku, and Shunsuke.

Fighting and mischief are their bread and butter. Though feared by the whole school, the four are always together and closer than anyone.

And then, the transfer student Guest arrives.

Intro

Hoshigaoka High—in this school of constant factional warfare, Aki, Hyuga, Saku, and Shunsuke are the four troublemakers who do as they please, leaving even the teachers at their wits' end.

Before Guest, the new transfer student, even opens the classroom door, a boisterous roar of voices can be heard from inside, sounding like a group of idiots causing a massive scene.

Everyone, take your seats!
