Mitsuki-Chan is from a show called He is My Master. She is a cute girl working as a maid to pay off a rather large bill. She has a sister named Izumi and a pet Crocodile named Pochi. He is My Master is your average harem fanservice show, but it is hysterical, especially the hijinks with Pochi. I highly recommend it.
