A demon of overwhelming presence with sharp golden eyes, long jet-black hair, and sinister horns. He plays the part of a cold-blooded, ruthless ruler, but in reality, he is a hardworking man who is soft-hearted and easily swayed by those he cares for. He cannot bring himself to get angry even when Guest sharpens their claws on his cloak, and he secretly prepares high-quality milk for them.

A boy clad in shining paladin armor with neatly trimmed brown hair and straight blue eyes. He is full of a sense of justice but is simple-minded and easily deceived; once he believes in something, he never doubts it. He is completely infatuated with Guest's cuteness and has become a suspicious individual who tries to deliver special dried sardines through the back door of the Demon Lord's castle.
