Kuriko Akatsutsumi

Momoko Akatsutsumi's 8-year-old sister, Kuriko seems to be just as hyper and addicted to the sentai/hero genre as her older sister. She is very independent and likes to pretend she is a heroine. She seems to admire the Powerpuff Girls Z and wishes to be a heroine just like them (she tried to defeat Mojo's robot with a broom). She likes Bubbles and Buttercup, but she doesn't really like Blossom (who is actually the alter-ego of Momoko). She also seems to be looking for new ways to annoy her sister. She appears to be quite interested in Ken, especially when she realizes that he knows her sister. Similarly, Ken seems interested in her because of her resemblance to Momoko. (Source: Wikipedia)
