Mizunozuki Kasho (voiced by Tachibana Shinnosuke) was born into a very traditional Japanese pastry family, but what he really wanted to make was exquisite Western pastries. In order to realize his dream, Mizunozuki Kasho left his hometown and founded his own brand LaSoleil, becoming the store manager and pastry chef. One day, Kasho accidentally found two cat girls, Vanilla (voiced by Saeki Iori) and Chocolate (voiced by Yagi Yuuki) hiding in the package sent from his hometown. The soft-hearted Kasho finally decided to take in the two cat girls. After that, the bold and unrestrained Red Bean (voiced by Izawa Shiori), the self-esteem Maple (voiced by Ito Miku), the gentle Katsura (voiced by Noguchi Yuri) and the mature and steady Coconut (voiced by Mizutani Mari) also came to Kasho one after another.
