Annerose's maid. She acts pleasant when Annerose is around, but is very rude and antagonizing to anyone else. Michiko can be downright cruel to certain people, as long as they don't die.

She detests her brethren of the Otherworld and loves the Human World, wishing to protect it. She wishes to be called Michiko and gets angry if called Fleuretty which is her true name from that side, she also dislikes being reminded of her true form as a Black Dragon, as she is more of a "swallowtail butterfly" in her own mind.
