“I want to be a true demon.”

A boy not older than 20 years wished as he looked at the sky.

People called him ugly, demon, and hideous.

He bared with it, but today he finally broke.

With a piercing pain in his chest, he died.

When opened his eyes, Logan found himself in another world and inside the body of a demon.

His wish was granted, but at what cost?

The true Demon!

Hm?
