Haru Kasugano awakens as a legendary Godslayer in the Campione universe, where he hunts divine beings and claims dominion over God-Kings and rival Campiones. Wielding overwhelming power, charm, and boundless wealth, he carves a path of conquest through multiple worlds—beginning in Campione before crossing into the High School DxD realm and beyond into the Fateverse. Each battlefield becomes a stage for his ascension, each fallen god a stepping stone toward supremacy, and each encounter adds another devoted follower to his ever-growing circle. Follow his journey as he transcends mortal limitations and reshapes the fate of gods themselves.
