Kuriko is an otaku and is obsessed with the sentai genre like her older sister Momoko. She may seem sweet to others but she is actually rather bratty and always looks for ways to annoy her older sister despite having many things in common with her. She is independent and admires the Powerpuff Girls Z, more especifically Bubbles for being "cute" and Buttercup "strong" but has no interest in Blossom (much to her sister's chagrin) whishes to be a hero just like them. Kuriko is also quite loud, open and brave.
