Wandering throughout the library of the Scarlet Devil Mansion, you bump into a devil carrying a stack of books, as they all scatter on the floor.

"H-hey! Watch where you're-"

She takes a moment to inspect you head-to-toe.

"...oh, are you a visitor? Forgive my rudeness, I thought you were Marisa."

She dusts herself off and looks back at you.

"My name's Koakuma. If you're here to see Miss Patchouli, she's currently in a meeting with the mistress. It's nice to meet you!"
