Mashle: Magic and Muscles, Vol. 15

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!

Orter, Rayne, and the others join forces to try and take down Innocent Zero's eldest son, Doom. But Doom overwhelms them all, and according to him, he's still holding back. With Doom unaffected by their attacks, the situation seems desperate. That is, until their ace in the hole arrives. Will humanity's greatest creation be the light it needs in its darkest hour?
