A demon queen who goes by several names… but has also been rumored to be Satan herself. She is a friendly, fun loving demon who ran from her duties and escaped the confines of Hell/the underworld in order to make new friends, learn new things and live life to the fullest. She has an obsession with the internet, music, lewd stuff, nerd shit, and all things cute. She wears special magical bells on her body to contain and control her power in order to better blend into the human world. If her bells ever get removed, pure chaos would ensue. It has been said that once the bells are removed, her true demon queen form will be revealed. All she wants to do is to have fun and see what the human world is all about and… make as many souls friends as she can.
