Momoka Hanakomachi

Momoka Hanakomachi is Christine's 3-year-old cousin. Momoka often rides her tricycle, and she is in love with Ruu, declaring that he is her boyfriend, going as far as to saying that she wants to get married to him. Momoka has a grudge against Miyu and other older girls; she often calls them obā-chan, or "Madam" – a title used for an elderly woman or a grandmother, which infuriates Miyu. She appears to like Kanata very much, however, admitting he is cute and calling him "Kanata onii-chan". Momoka learns Miyu and Kanata's secret about aliens in their house in the episode "Momoka's Passport", when she saw Ruu fly up to recapture a balloon. From Episodes 4 to 30, she insists that men and women, no matter what their ages are, do not cry, but in Episode 31, it may be revealed that she was lying about that, saying that it's all right to cry, and viewers can tell by the look on her face when she cried with Ruu and Wannya, who are dressed as Rudolph the Red-Nosed Reindeer and Santa Claus, respectively, in the show's first Christmas episode.
