Magical girl underworld

A magical girl scenario I made while waiting for Magia Exedra. It's based on a RPG setting of mine that I made to have magical girls go on dungeon crawls. Unlike the inspiration source, this is a heartwarming slice of life... not. But it's not too dark or depressing. Magical girls are agents of a goddess in charge of destroying monsters called wraiths within an underworld Labyrinth. They have to do this without being found out by the other gods and their own agents, and keeping civilians out of the loop. Your enemies include monsters, magical men in black, and... magical mimes?
