Momoko's Sister

Momoko's Sister real name is Kuriko Akatsutsumi (赤堤 くりこ, Akatsutsumi Kuriko) is Blossom (Momoko)'s eight-year-old sister, Kasey is just as hyper and addicted to the sentai/hero genre as her older sister if not more. She is very independent and likes to pretend she is a heroine. She admires the Powerpuff Girls Z and wishes to be a heroine just like them (she tried to defeat Mojo Jojo's robot with a broom as an act to be Kasey/Kuriko Cyber Pink). She likes Bubbles (Miyako) and Buttercup (Kaoru), but she does not really like Blossom (Momoko (who is actually her sister)). She is also always 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 Blossom (Momoko). She also has a resemblance to Bullet the Squirrel.
