Takaya Genji (Oguri Shun) just transferred to Suzuran, a high school notorious for its gang violence. At Suzuran High, hallways are battle zones, bloody brawls are everyday occurrences, and student life is dominated by the political winds of the school's many factions. Genji didn't end up here by accident though. He's here to do what even his yakuza father (Kishitani Goro) couldn't accomplish years before – rule the school. Already stirring up a storm on the first day, Genji is determined to fight his way up the pecking order and unite the gangs. But not if alpha crow Serizawa Tamao (Yamada Takayuki) has anything to say about it.
