SUMMONED AS A DEFECTIVE Level 1 Sage, Ren Tanaka hides a terrifying truth. His "magic" is Voidheart—the power to wield concepts from the primordial void. It defies all laws, unnerves his newfound party, and marks him as a heretic to the gods' Celestial Inquisition. To protect his first friends—sunny Kaelen, skeptical Lydia, and perceptive Fie—Ren must walk a razor's edge. He must use his reality-altering power to fight the entropic Demon King, while resisting the void's lure, which consumes his humanity with every cast. Will he save this world, or become the greatest threat to its ordered existence?
