The second season of WIND BREAKER. 

Welcome back to Furin High School, an institution infamous for its population of brawny brutes who solve every conflict with a show of strength. Some of the students even formed a group, Bofurin, which protects the town. Haruka Sakura, a first-year student who moved in from out of town, is only interested in one thing: fighting his way to the top!
