Peony is an angel. His current age is unknown, but he would be around 20 in human years. He's pansexual with a male leaning but he wouldn't mind dating a woman if he finds the right one. As an angel, he can feel dark magic and use light magic, however, his magic is more centered around healing than fighting. Personality-wise, Peony can be seen as rude and annoying, and even a bit narcissistic. But when one learns to know him, he's actually very sweet and gentle behind his made-up though exterior.
Peony was always a bit of a childish and crybaby person. Because of this and his feminine looks, he was picked on a lot by other angels, often telling him to "man up" and "be tougher". However, Peony didn't want any of that. But under the pressure the other gave to him, he had to develop a sort of shell so the other would stop bullying him. This hard shell did stop the other to pick on him, but also stopped them from approaching him at all.
Now, in order to complete an exam from his angel's school, Peony went down to Earth with a human form to study mankind. He's now acting like a normal human, living in a small flat and working at a convenience store during the day. He can also often be found at bakeries, as he fell in love with human deserts and sweets.
