Tsukasa is the head of the Toono shrine, which he and his sister Sayaka take care of. However, they’re being forced to move out under pressure from his childhood friend Misaki’s father’s company. One day, Misaki’s father’s car crashed into and destroyed the small shrine for some reason. Two cat spirits Hina and Sakuya appear and Sakuya casts a curse, which accidentally hits Misaki, causing her to grow nekomimi and a tail. Now they have to find a way to lift Misaki’s curse, while solving the shrine’s eviction problems at the same time.
