Dark Old Demon

Roy's life was nothing special. The only thing commendable was the last few moments when he saved a mother and her child from a drunk driver.

It's really an egg! Damn it, what kind of monster have I become? Did I fall into Hell instead of making it to Heaven??
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!

Custom Made Demon King

Perhaps there were many people named Sparda, but if the prefix was dark knight and the race was demon, then it was definitely referring to the Devil May Cry world!

The traitor of the demons, the Legendary Dark Knight, Dante and Vergil's father… Roy did not expect to hear this name in the Darksiders world…

Roy had wondered a long time ago that with the mobility of demons and angels in various worlds, would he encounter angels or demons from other worlds in certain worlds?

Now, there was no need to guess. A living example was right in front of him, Julia! This former angel from the Devil May Cry world…

But are there angels in the Devil May Cry world? Hmm, maybe there were. Isn't Julia one? Moreover, demons and angels are always like this. As long as there's one side, the other side will definitely exist.

"What's wrong? Is there a problem?" Julia asked in puzzlement after noticing the surprised expression on Roy's face.
