Arifureta: From Commonplace to World's Strongest Zero Vol. 3 (manga)

THE DEITY OF THE DESERT

"I'll never use my power again..." So swore Naiz Gruen: a mage with the power to warp space itself. Though he inherited the ancient magic of the gods, it brought him nothing but tragedy, and so he cast it aside. Meanwhile, the Liberators Oscar and Miledi are looking for new recruits. They've come to the red sands chasing rumors of a "desert fairy," which turns out to be none other than Naiz himself. They'd make a powerful team, but the Holy Church isn't about to let them join hands in rebellion!
