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!

In Roy's Radiation Perception, this sudden beam of light was terrifying. It burst with powerful radiation fluctuations and frequencies, full of destructive power!

The speed of the light beam was so fast that it was too late for Roy to teleport away. He could only subconsciously activate Ice Block again, condensing a thick layer of ice around his body as protection…

Boom! When the ice finished condensing, the light beam hit the ground not far away from Roy. Instantly, the formidable holy light power contained in it erupted!

Roy and the Red Sea Egg, which had lost its roots, were blown away in a flash, blasted thousands of meters away by the shock wave.
