[Transmigration + Demon Slayer + Neither Entirely Good nor Evil]

After transmigrating into the world of Demon Slayer, he suffered the extermination of his entire clan. He was lucky enough to survive, only to learn that he was afflicted with a disease and had little time left. Fortunately, he encountered a descendant of a medical family who had been cursed…

He drank the elixir of immortality and became a special Demon King!

He simulated Blood Demon Arts and forged a new legend!

He redeemed the Upper Rank demons and changed the fate of the Demon Slayer Corps!

After the Upper Ranks were redeemed, the lone demon Muzan Kibutsuji declared, “Once I devour you, I’ll be the strongest in the world!”

Jiu Changhe: “Come and eat me.”
