Raku-chan (Japanese: 楽ちゃん) is the protagonist of Nyan~ Neko Sugar Girls. She is a cheerful, outgoing catgirl who loves to spend time with her friends Koneko-chan and Hitoshi-san. She often uses Japanese phrases such as “kawaii”, “sugoi”, “nya”, and “desu” every time she speaks.

Raku-chan can be described as childish, carefree, innocent, and a bit of a ditz. She is constantly whiny, but her intentions seem to be good until she decides to take advantage of the attention she gets, when Hitoshi and Koneko try to calm her from her rabies in Episode 4. Her immature behavior may imply that she is the youngest out of the trio.
