Naraku, a modern human, transmigrates into the world of Tales of Demons and Gods as a young master of the Sacred Family. He inherits a powerful God template—a scientific seal—that accelerates his cultivation by absorbing the world's karma. Using his status, Naraku gathers resources, tricks, and provokes others, all while maintaining a heroic façade. His powers, drawn from dark arts and demonic cultivation techniques, evolve as he absorbs more energy and abilities. Behind the scenes, he orchestrates events to further his grand goal: transcending life and death to achieve immortality and divinity.
