Rhegius

Hundreds of years ago, he was a Demon King who made a name for himself during a time of great upheaval. However during a decisive battle with the forces of light, he was defeated and fell into a coma. During the present age, he was revived by a group of demons led by Arisu who wished for the birth of a savior.

Rhegius has the dignity and charisma of a Demon King but is surprisingly friendly with his subordinates and deeply cares about them. On the other hand, Rhegius will not forgive those who disobey him and will attack his enemies mercilessly.

Plans to break the heroes' will by using his "Black Seal" magic.
