Konna Nekomimi, Suki desu ka?

Midori and Satoshi are students at Kuromori Academy, a magic school. They've been together since childhood, and when Satoshi decided to study magic, Midori followed him even though he doesn't really like magic. When Midori casts a forbidden spell his punishment is to have cat ears for a week. Will Satoshi also break the rules so that he too can have cat ears?
