Before the events of the story, Mimi was chosen to be the mascot for Fancy Island, an amusement park announced on August 20th, 2009. She starts by helping the visitor, giving instructions on how to proceed and such. Mimi has 2 friends that somewhat act as mascots, consisting of Nyami and Yomi. Nyami's hobbys consist of punk rock appreciation and "always being fine", meanwhile Yomi's consist of Cosplay and constantly drinking bubble tea. In short, Mimi is a chibi cat girl.
