After he was defeated by the Hero, the Demon Lord Veltol went to sleep...to come back after 500 years and take back the world for himself. However, the world had changed totally when he woke up. Alnaeth, the planet he ruled, merged with the planet of another dimension called Earth. Now he is in Shinjuku, the great cyberpunk city full of neon signs and skyscrapers. With Machina, one of his six dark peers, Veltol tries to be the King again--but things won't turn out as he expected. He finds out that Marcus, another one of his dark peers, lives close. But in fact, he turned out to be the worst foe in this world! Veltol must find a way to restore his power by collecting people's trust to him. How? Of course, by earning lots of subscribers!
