Shun Oguri is Genji, a student freshly transferred to Suzuran high, a school legendary for the out of control violence that dominates social life there.

The students are banded into factions, rival gangs openly battling for control in the halls, teachers or any other form of authority absolutely impotent. Its the sort of school nobody in their right mind would willingly choose to attend but Genji has done just that, transferring to the school with the goal of doing what nobody has every done in the entire history of the place battle his way to the top of the heap, unite the factions and be recognised as the undisputed king of Suzuran, a feat his yakuza boss father tried and failed to accomplish himself as a student of Suzuran decades before.
