Nikki Starlight

Nikki Starlight pretended to be the girlfriend of the Guitar Ghoul, a popular singer who always performed in a face-concealing costume. In fact, she was the Guitar Ghoul herself, because she wanted to share her music without sharing her life. This left her open to an impostor playing the part and acting as a monster.
