“Humans remain nothing but a blight upon us demons.”

A boy who was once bullied in his past life is reincarnated into another world as Demon King Noct, seeking to rule over everything. However, just before achieving his ambition, he is sealed away through a cunning scheme along with his loyal generals.

Three thousand years pass, and Noct finally succeeds in breaking free from his seal. Before him lies a world where grotesque monsters prey on humans, and those very humans oppress the demon race.

Upon learning of the world’s devastation, Noct sets his plans into motion, gathering his former allies from the Demon King’s army to reclaim dominance. His first order of business: rescuing demons who are about to be sacrificed to monsters and exacting vengeance upon humanity.

“Kneel before me, world. My kin, commence the march!”

Thus begins the ultimate Demon King’s conquest for world domination!
