Mashle. Magic and Muscles. Volume 5: Hajime Komoto

Can muscles crush magic?!
In the magic realm, magic is everything-everyone can use it, and one`s skill determines their social status. Deep in the forest, oblivious to the ways of the world, lives Mash. Thanks to his daily training, he`s become a fitness god. When Mash is discovered, he has no choice but to enroll in magic school, where he must beat the competition without revealing his secret-he can`t use magic!
Mash and the gang are in a celebratory mood after defeating the Magia Lupus, but it isn`t long before the mysterious criminal organization Innocent Zero comes to threaten the peace! Abel is overwhelmed by the power of the dark-magic users, but Mash refuses to back down. Sadly, however miraculous Mash`s physical strength may be, it`s not magic, and when rumors spread about his inability to use magic, Mash finds himself in magical court!
