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!

Right before the destined day of the eclipse, an army of demi-humans invade, throwing the land into chaos. Renatus and the other visionaries launch a counterattack, but they immediately find themselves face-to-face with Innocent Zero's four remaining sons. Later, after a crushing display of power, Innocent Zero demands the frightened populace hand the unconscious Mash over. Can Meliadoul find a way to recharge Mash in time for him to defend himself?
