[Crossover] Welcome the Tenth King Back to His Throne!

The terror of the world, the embodiment of evil, the source of all sorrow and fear in the mortal realm. The tenth legendary King! Asa had always believed this was what he was. Until one day, he woke up in this world and opened a history book. "In the ancient war, the gods sealed the nine Kings..." What!? "Each of the nine Kings had their own duties and territory, ruling the world for tens of thousands of years." What!? "The God King of Light had no family or kin. He stood alone at the pinnacle of the world, awaiting the fate ordained a thousand years ago..." What!? No family!? Asa snapped the book shut. Asa activated his golden finger. He looked down at the barren land waiting to be rebuilt and smiled crookedly. Target: the Cursed World! The ten-thousand-year deadline is here. World, welcome your Tenth King back to his throne! Original male lead and second male lead; transmigration into an anime world. Cool, outrageously powerful King of Light who loves to play x proud, confident, taciturn King of Darkness Theme: Settle down and build a good life
