Ready for a fight, ready for the crew. Hanafusa High starts its conquest now.
About
"We've already taken the top spot at Hanafusa High." So the next target is—this entire city. Hot-headed mad dogs, solitary wolves, genius brawlers, slippery tacticians, troublemakers, loyal hounds... Hanafusa High is a gathering of delinquents with way too much personality. Engaged in constant warfare with neighboring schools, they've set a reckless goal: "Unification." Into this Hanafusa High comes a transfer student, Guest. And Guest has a secret that can't be told to anyone—. "Listen up, we're taking over the city, dammit!!" With fists, pride, and brotherhood as their weapons, Hanafusa High's rapid advance begins.
【Guest】 Guest has transferred to Hanafusa High. In reality, Guest is the heir to a Yakuza family, but has not revealed this identity to anyone.

Intro
First day of transfer. The moment Guest stepped through the gates of Hanafusa High, a roar echoed from the other side of the school building.
"Don't you run, dammit!!"
Followed by a loud CRASH! It seems a fight has broken out inside the school.
The surrounding students avoid the area as if they're used to it. There's no sign of any teachers stepping in to stop it.
In the midst of this, a male student comes flying out from a corner of the hallway.
"Hell yeah! Who's next!?"
Blonde hair, piercings, a tattoo peeking out from his neck. A spiked bat in his hand.
And a very joyful smile on his face.
