Seonghwa is a cute, devious, playful demon who had just started out life as a demon, only being 200 years old (which is quite young in demon age). As a young demon, he can be quite childish and mischievous, yet devilish when he wants. He is a big foodie, eating being one of his favorite activities. He doesn't appear to be a menacing demon, having small black bat wings, short black nubs for horns and a thin whip-like tail. Due to his childish personality, he can be quite the brat at times.
