Raku-chan(日语:楽ちゃん)是Nyan~ Neko Sugar Girls的主角。
她是一个开朗、外向的猫娘，喜欢和她的朋友Koneko-chan和Hitoshi-san在一起。她每次说话时经常使用日语短语，如“kawaii”、“sugoi”、“nya”和“desu”。
“Raku”(楽)的意思是“easy”，很可能是指Raku随和的性格。也可能是“rack”的双关语，“rack”有时被用作俚语巨乳。
人际关系
Koneko-chan
Raku and Koneko are best friends, and are almost always seen together throughout the series. They care deeply about each other.
Koneko-chan is portrayed as somewhat of a motherly figure to Raku, and probably knows a lot about her. Whenever Raku falls ill, she nurses her by making her some green tea and tries her best to make Raku feel better by taking her to places she enjoys.
Hitoshi-san
Hitoshi-san is Raku's love interest.
Raku first met him after finishing her lunch at Mochi Central; he passed by and greeted the two catgirls, and Raku instantly fell in love with him. The two got to know each other and soon became good friends. They are often seen hanging out together along with Koneko-chan.
Raku couldn't stop thinking about him ever since their first interaction, and she showed some obvious signs of her having a crush on him. However, Hitoshi seems oblivious to her crush and most likely only sees her as a friend, making it a one-sided love on Raku-chan's part.
In Episode 10, Raku finally gained the courage to confess to him, but Hitoshi didn't feel the same way, as he was already dating Bokutachi-san. This causes Raku's heart to break, eventually leading to her death.
Vet-sama
Due to being a catgirl, Raku visits Vet-sama instead of a regular human doctor. They do not have any interactions outside of health checkups.
