The strange and supernatural have returned. Demons cannot be killed, nor can they be wiped out.
Only demons can fight demons.
I've slain countless monsters to protect the human world. But each time I crawled out of a mountain of corpses and sea of blood, I turned around to see terror in people's eyes and hear them cry out in trembling voices: “A great demon... He's the biggest demon of all!”
I slew demons for humanity, yet humanity regarded me as a taboo.
Until the day a doomsday-level demon king descended, with no one at my side.
I tore off my disguise, and overwhelming demonic energy swept across heaven and earth. Looking back with a cold laugh, I said, “Since you call me a great demon, today I'll show you what it means to be the true king of ten thousand demons.”
