Mashle: Magic and Muscles, Vol. 3 by Hajime Komoto

[Viz] 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! Lang’s vicious hunt for coins is in full swing! To stop them from monopolizing the chance to earn a Divine Visionary position, Mash teams up with his Adler compatriots. Afterwards, the Sixth and Seventh Fangs of the Magia Lupus swoop in to attack Mash while he’s cleaning the owl huts. Then, when his friends become the next victims of the Magia Lupus’s callous dog-eat-dog philosophy, an enraged Mash is ready to face them head-on!
