Mashle: Magic and Muscles, Vol. 5: Volume 5  (English, Paperback, Komoto Hajime)

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!
