みい, Miitan
Mii the youngest sister the 11yearsold girl is by far the most energetic and naive of the three. Her lightpurple hair is often tied in a doublebun on her head except when she cosplays as quotMagical Girl Miiquot. Mii has an obsession with defining plushy things especially girls breasts and constantly touches things that are especially people. Being so young she quite naive and energetic. Through she passes through time like the rest of the girls her very naivity and energy allow her to overcome most of the jumps with ease. quotMagical Girl Miiquot was a specialized cosplay costume she had created in the episode where he met a chronically ill girl she attempted to cheer up and it apparently cost a lot of money but Ai seemed easily able to pay for it. After this she often wears it around and pretends to help stop evil and believes she has superpowers. Later during the episode the girl collapsed from overexertion playing with Mii. Mii tried to use powers she thought she had to heal her friend. The attempt was successful and Ai revealed to the viewers that Mii039s special power was healing. However Mii remains unaware of this for a good portion of the season and continues to believe that she has other powers as well. Source: Wikipeda
