Born from a forbidden spell inside the God-Realm, Crish is the child of the Demon King — a being who should never have existed.
At age five, his dormant demonic aura awakened, triggering chaos in Heaven. Terrified by prophecy, the gods cast him out, sealing his powers and abandoning him in the Mortal Realm.
Years later, after living an ordinary mortal life, Crish is suddenly thrown into a new world of kingdoms, monsters, and ancient prophecies. His sealed powers tremble inside him. The shadows of Hell search for him. Heaven fears his return. And a mysterious princess guides him toward a destiny he never asked for.
As Crish rises through trials, chaos magic, and political war, he begins his Ascension — not as a hero or villain, but as the Forbidden Successor, whose existence can rewrite the fate of all realms.
