Knuckle-busting brawls, badass babes, and the toughest student body ever to mix it up under one roof. Welcome to Todo High, where the only rule is: get strong or get schooled.

A supernatural smackdown shakes the holy ground of the Enmi and Soichiro is led further down the path to the awakening of his demonic powers. Maya heads for Kyushu while the members of the Juken Club assemble to try and save Soichiro from himself. Surrounded by the members of the "F," Bob and Masataka will have to give it everything they’ve got to survive! Masataka’s true power is put to the test—with his friends in need of help and a host of enemies in need of a proper thrashing, can his fists do away with this new danger?
