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

<p>Hearing Roy say that he was a thief, Tyrael pointed his holy sword at him. "Did you think I couldn't see through your scheme? You deliberately got me to bring this soulstone back! Although you've fulfilled your wish and found the location of the High Heavens, you can forget about taking it back! In the name of the High Heavens, we will judge you!"</p>

<p>"Tsk tsk, you're talking like you're standing on the moral high ground again! You angels are always like this…" Roy shook his finger. "Tyrael, although you were called the Archangel of Justice in the past, you really can't represent justice! In my opinion, the war between angels and demons isn't a war of justice and evil, but just a boring fight… Look at the scene in Sanctuary now. The angels are killing the nephalem. If you really call yourself justice, then tell me. Will you judge the culprit who caused this killing: your brother, Imperius?"</p>
