Their mental fortitude and their clench hands! Their objectives? Turning into the lord of the town! It is in this air Takeshi Yamato, a youthful highschooler from tokyo, moves in. Ex-group pioneer finished with an amazing mystery, he is chosen to overlook the past and become a socially worthy person... Be that as it may, between his mystery being discovered, the battles, the young ladies and the destroying with his companions, he is a long way from turning into a model highschooler.
