Story
Humanity's world was destroyed by the Demon Kings. Stripped of everything, Awakener Ash Si sacrificed himself in a devastating explosion to drag Demon King Voralune, The Glutton, down to hell. Instead of death, he opens his eyes ten years in the past, long before the tragedy occurred. He discovers his powers have awakened early, and surprisingly, he also possesses Voralune’s power of Gluttony. Armed with this advantage, Ash decides to act in advance. With his return, everything in the world seems to be changing...
