Who's the boss of this school?

Trouble finds Maeda, a good-for-nothing outcast with dreams of becoming a boxing champ, soon after enrolling at Teiken High School. His cavalier clumsiness has a way of attracting attention from gang leaders, school staff, and the precocious schoolgirl Chiaki. When a dangerous new gang leader threatens to upend order in the school, Maeda puts his training to work — along with every brain cell he can muster — to protect the balance of power.
