Join Roy as he ventures through various worlds with the Custom Made Demon King System—a system that allows Roy to draw anything he can imagine and create it through exchanging souls!

The star admiral who had been slagged by him: “Don’t be reluctant anymore! I’ve always known that you didn’t betray me.”

The entertainment mogul who was slagged by him: “Don’t make any noise. Honey, will you come home with me?”

The dark sentinel who was slagged by him: “Now, do you still want to say that it is not my child?”
