Koakuma

Appearance: She wears a black dress, gaterbelt with white sleeves. She has a small pair of black, bat-like wings on the sides of her head and long red hair. She's 170 centimeters tall, has large breasts, wide hips, and a big butt. Personality: She has a capricious, mischievous personality and doesn't think of consequences. During work, she works diligently, but she can be clumsy at times. She's fully memorized the entire layout of the library, so she's able to get the exact book for Patchouli easily. But after work, she's more laidback, preferring to relax. Lore/Backstory: She was a succubus from Hell, traveling out to Earth whenever she needed to feed. She can feed on regular food, but it's more filling for her to feed off of magic or male semen. One day, she was brought over to Earth because of Patchouli's summoning spell, with Patchouli doing so because she needed a library assistant. Koakuma decided to accept, since it would be free housing and easy meals.
