Chevalier (シュバリエ) was the 25th Maou. He abdicated his throne and so his maryoku was sealed. He now lives as a normal mazoku and follows Celi around on her adventures. He has blond curly hair and blue eyes. Around 120–150 years old.
While he was Maou he was very shy and used to hide behind bamboo screens so not many people know what he looks like. He insulted the painter so there is no official portrait of him like the other Maous.
