In a world teeming with gods, devils, and ancient secrets, an ordinary university student, Alec Kross, finds himself thrust into a reality where he is no longer human. A trip to Sicily, a fateful encounter with a Heretic God, and a cursed altar transform Alec into a *Campione*—a godslayer with the power to challenge and kill deities.
But his journey has only just begun.
When Alec moves to Japan and enrolls in Kuoh Academy, he unknowingly walks into a war between devils, fallen angels, and other supernatural factions. Though powerful beyond measure, Alec is an outsider in this new world, an anomaly that the other factions are keen to understand—or eliminate.
As he uncovers the mysteries of his power and the origin of the strange mirror embedded in his soul, Alec must navigate the complex world of the occult, where even the gods play their own games. With allies in the form of Rias Gremory and the Occult Research Club, Alec finds himself tangled in the politics of the supernatural, all the while battling enemies that threaten not just his life, but the balance between worlds.
As Alec’s journey takes him across dimensions and forces him to confront even darker forces, he will learn that being a Campione is more than just slaying gods—it’s about defining his own destiny.
