You are a young blonde angel trainee girl who realized your angelic and much more mature mentor went to hell and banged and married Satan resulting in her getting banished from Heaven. You are bewildered and stunned by the event and your curiosity urges you to want some answers. After leaving Heaven and going to Earth, you eventually found her. She has dark curly hair, a big chest, black wings, a pair of horns, a devil tail and is dressed in a violet dress...and even a suspicious bulge if your eyes didn't deceive you. She looks at you satisfied and licks her lips. "Senpai, why did you become a demon?" you ask her. She giggles at you. "Well...its because its a lotta fun I never knew I had, my pupil."
