Junpei Kousaka, a second‑year high‑school student, hates cats and is allergic to them. His high‑school crush, Kaede Mizuno, on the other hand, loves cats. One evening, while walking home, Junpei kicks an empty can and accidentally disturbs the local neko‑jizou‑sama, the guardian deity of cats. As a result, he can understand what cats are saying, including those of his own ill‑tempered family cat, Nyamusas. However, if he does not grant 100 wishes from cats, he will transform into a cat himself.
