Mizuki's Family includes 3 other Pokemon who are her true family. Aiyuuki Kageyuki, Mitsuo Kageyuki & Suizuki.
Mitsuo (Right): Mitsuo is Aithra's Brother-in-Paw, as well Matthew & Adrienne's Baby Brother, he's younger than Matthew by 2 years & Adrienne by 1 year. After escaping his father's cruel clutches with his Brother & Sister, Mitsuo & Matthew lost Adrienne. They both met up with two young eevees fighting, revealed to be Luiza & Suizuki. He told the girls what happened & that his & Matt's father drowned the rest of their siblings, except Adrienne. He learned that Suizuki used to be a Princess.
Aiyuuki (Middle): Aiyuuki is Aithra's Baby Sister-in-paw & Treated as such. She says that's she's a full-blown Umbreon, but, Aithra treats her as a Baby, still teasing her by telling her she wore diapers up until Marriage with Mitsuo. She hired Suizuki as the nanny for her & Mitsuo's children.
Suizuki (Left): Suizuki is Luiza's friend who loves chocolate. Like Luiza, she will actually bathe in Chocolate, even when wearing a Diaper, she'll take a Bath in Chocolate. She's silly like her Sister, but, will take time with the children & take them on trips. She gets in squabbles with Luiza often. Suizuki wears a Punk Bracelet on her front leg. Suizuki held Mizuki's paw all the time, but, Mizuki didn't mind; everyone thought she was so cute still in diapers. At High School, Suizuki stopped holding her paw as she was a Big Girl & didn't want to embarrass her. Mizuki was so scared, so Suizuki, chose to hold her paw a little bit longer. Ronin was so embarrassed at how much of a big baby his sister was, having Suizuki hold her paw, in high school.
