Histoire
The mighty hero died in a final battle with the Demon Emperor. Five years later, he awakens in the demon camp, reborn as the weakest of their kind. But his soul triggers the ancient Serpent God’s power hidden within his body. Once a hero feared by villains, he now walks the world in a demon’s body. And this time, the bloodbath he unleashes will shake both sides of the war.
