Chapter 1 - Remember

A storm is coming...

Many years ago the demon king abruptly vanished within the castle walls, not being seen till a thousand years later in the human world. A demon found him as a child as they were passing through the human relm. When they took a look into his eyes they could tell who he was, they kept his reincarnation a secret until they knew he was the right age to come back and claim his throne.
