Shouichi spent most of his life living and working in his father's bakery. Like many young men, he left home for college upon graduating from high school. However, Shouichi's father has fallen ill, and now Shouichi must return home to manage the shop. In doing so he'll be reunited with beloved friends and forced to confront long standing family problems.

On his first night back home, a magical catgirl named Mio mistakenly curses Shouichi to turn into a cat at night! It's not all that bad though, as the girls just love holding cats. Some will even bring him into the bath with them!
