Mitoto (九羅密美兎跳 Kuramitsu Mitoto) is the daughter of Minami, as well as the mother of Mihoshi and Misao.
Unfailingly cheerful, Mitoto Kuramitsu works as sanitation engineer (cleaning lady) for the Galaxy Police. Nabiki has described her as making Kasumi look like a slot. She met Seina when he was first taken from Earth to the G.P. Academy, and was taken by Seina's hair, which she constantly pets. Since then, Mitoto would be occasionally popping into Seina’s life from time-to-time, often helping him out during certain events in the boy’s life (like the time Seiryo held up Seina’s body enhancements so that the boy could wash-out, where she supervised Seiryo in cleaning toilets).
Mitoto shares certain traits with her daughter Mihoshi, namely her odd luck and carefree, yet clueless attitude. Also, Mitoto seems to have the odd habit of appearing in places where you least expect her to be; sometimes on a G.P. battle cruiser or a pirate ship, where she would be cleaning away without a care in the world.
There is a running joke that she knows almost everyone in the galaxy because she cleans for them. She has even been in General Daluma's "secret" fortress, and remarked on the cleanliness of its floors. She approved of Misao's proposal to Mashisu and convinced the Kuramitsu family council to approve of the wedding.
