Wind Breaker (Series) favorite_border

From Book 1: Who cares about grades? Here, the law of the street reigns. Furin High School is infamous for its ultra-combative student cliques — what sounds like paradise to Haruka Sakura, who transfers there in the spring with one goal: to fight his way to the top and become boss of all bosses. But to his surprise, he discovers that the local gang, who call themselves "Wind Breaker," is less interested in brawling and more devoted to protecting their neighborhood.
