Anime Multiverse | DxD: Origin Mage / The Godslayer’s Path

He was reborn in a multiverse ruled by demons, angels, and gods… yet to him, even they are but stepping stones to greatness. Kai, granted a second life in a world woven from dozens of anime universes, knew from childhood that his destiny was not merely to be Rias Gremory’s friend. His true path lay in *Origin Magic—an ancient power that grows with the comprehension of the cosmos’ secrets. But Kai didn’t stop there. By creating the Interworld Demon Contract System, he began recruiting "demons" from other realities, extending his influence far beyond the DxD world. Now, his retinue consists not of mere servants but legendary figures from across the multiverse: - Kasumigaoka Utaha ["Master, I need to replenish my mana again~"] — A genius writer whose words reshape reality… if only she had enough "mana." - Akame ["Master, care for some meat?"] — A ruthless assassin offering not just her blades but her loyalty. - And many more, whose names alone will strike fear even into Olympus.
