Simple Sketch for my Visual Novel - Koakuma

From all the characters I drew so far, Koakuma is the only one who doesn't have a storyline yet. Not even a single idea... There is very little known about her, and making up background info is really not my best point . But yea, I always imagined her to be some kind of maid for Patchouli, bringing her tea and cleaning up her mess XD.
