"He's the toughest opponent the GCPD has ever faced, surpassing even the Joker in being hard to catch." - Jim Gordon

"Gentleman Phantom Thief, Silver Wing Magician, Miracle Maker... No one knows who he really is. His name, gender, appearance, and age are always a mystery. I very much hope that such a person can join Task Force X."—— Amanda Waller

"I still don't understand how he managed to steal the Lantern Ring from me in my face." - Green Lantern

"Kidd the Kryptonian was the first person to infiltrate the Fortress of Solitude perfectly bypassing the Kryptonian security system. It still shocks me when I think about it." -Superman

"I prepared over a hundred backup plans for him, but ended up discarding them all because he had to refresh my intel every time he showed up." - Batman

"Although I don't want to admit it, but he is more popular with women than me, which is really reconciled." - Ye Yi

"If you want me to say, they are all talking nonsense. Taking away the treasure in a high-profile manner in front of everyone and then leaving gracefully and calmly is a fake monster thief! A real monster thief would have to rack his brains for several days to write a simple notice letter. It looks gorgeous on the way, but it’s like walking on thin ice for fear of being beaten to death... First of all, I have to think about what the new goal is, how about the miracle machine?" - Dean Suston

Luo Yi, a high school dropout in his original world, was isekai’d into the world of the Witcher 3. Starting out as a weak boy named Roy in the village of Kaer, Lower Posada, he was determined to grow stronger, no matter what it took. The first step toward becoming a legend was to kill. And his first kill was… a rooster. ‘You gain 1 EXP.’ Of course, Roy had his own cheat system like all the other isekai protagonists. His first step to becoming a legend started now…

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!
