Masurao - Hihon Gikeiki

Takeshi Yamato is a stout high schooler, the charismatic leader of a gang of swashbucklers. But, in reality, Takeshi lets off steam with fights to distract himself from the problems due to his ... disproportionate manhood of him! When his family moves to Osaka, Takeshi hopes to start from scratch in a place where no one knows his secret and enjoy the joys of youth he has always dreamed of. Italian edition by JPOP available
