Mashle. Magic and Muscles. Volume 11: 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!
With Levis defeated, Mash must face his toughest opponent yet-his brother Domina, wielder of water magic. Desperate for the approval of his father, Domina aims to claim the Wand of Beginnings, which Innocent Zero could use to bring the world to ruin. To put a quick end to their bout, Domina summons a power as devastating as a Divine Visionary`s. But Mash has a trick up his own sleeve. Will Mash come out on top in this sibling rivalry?!
