Junpei Kousaka is a second-year high school student who despises cats and has an allergy to them.
Junpei wakes up from a wonderful dream, where Kaede Mizuno, the perfect girl, confesses her love for him. Unfortunately, he has this peculiar sensation, one he has had for long time and that makes him feel miserable. And yes, a cat is near and spoils the perfect dream.
The funny thing is, Junpei can hear the cat talk, yes, talk. He skips breakfast and leaves his house to avoid the cat otherwise, he will start sneezing. He goes to school and starts his little rant about hearing cat’s talk with his friends. Thinking he’s crazy both his friends calls Kaede over to talk with Junpei, embarrassed, he leaves the classroom and hides.
Walking home he recalls something that happened the last day when he kicked a can and it landed in the cat shrine’s place. Realizing that he has knocked the cat’s heads over, somehow he knows he has been cursed. The family cat, Nyamsus, appears and reassures him that he has been cursed.
A bald man appears and brings him to a temple. Changing into his monk outfit, the guys starts preaching his 100 cat related stories. Another cat, named Tama, appears and tells Junpei to overcome the curse he would have to do 100 good deeds, if not he is going to turn into a cat. Horrified being turned into the cat, Junpei leaves the temple with a worried looking face.
At the library, he decides to do some research to break his curse. At that time, he receives a phone call from his sister, after that, he goes to buy some groceries and finds Kaede, who walks along with him. At that time, he is able to see the affection that Kaede has for cats, but for some reason, cats react strange to her.
Junpei Kousaka has a chronic allergy to cats. He lives with his mother and sister, who loves them. To complicate matters, one day he accidentally destroys the statue of a cat deity, and to compensate for it, he must make use of his newfound ability of communicating with cats to fulfill one hundred requests of help from them, otherwise he will be transformed into one.
Kaede Mizuno is Junpei’s classmate and crush who is totally oblivious of his feelings for her. Despite loving cats, her family has four dogs in her home, thus cats tend to avoid her as she always carries their smell.
