Suzaku Demon

朱雀門の鬼

He was once a highly skilled flute master. However, driven by envy, he transformed into a demon who challenges people to a game, promising the most beautiful woman in the world to the victor. Even if he is not an evil demon, he claims what the losers offer. Despite being a devil, he has not lost his exceptional flute-playing ability, and he is the one who gives the main character his flute.
