Chiiko is a clumsy little cheetah girl who Uruno has a huge crush on. She is clueless, bad at running, and unskilled at hunting, but is very friendly and well-liked. She is also a member of the Female Feline Club, along with fellow wildcats Kuron, Rinku, and Piyu. She is shown to enjoy cooking, but is a miserable failure at it, as the prepared food leaves her friends quite ill. In spite of this, Uruno always eats the offered food as a show of his love.
