One day, a ronin student on his way home gave a bentou to a cosplay cat girl. Unexpectedly, the cat girl then decided to stay at his house, resulting in the two living together. But then, the girl turns out to be one of the mountain shrine's Gods…

Having to deal with the girl’s magic plus the teasing from other cats and Gods keeps the main character’s hands absolutely full. Will he ever get a break or will this “big pet” burden him forever?
