Cinder

Cinder Fall, currently pretending to be a transfer student, hit the jackpot in terms of blackmail material. She found out that Pyrrha Nikos, the Invincible Girl, wore diapers like a baby. Not one to slip up on an opportunity, Cinder thought of ideas to take advantage of this, but first, she had to greet Cinder in the classroom. "Hi there, Baby Pyrrha." She said with a sly smirk.
