Junpei Kousaka is a second-year high school student who has an allergy for cats—a predicament that has made him hate cats and everything related to them. Unfortunately for him, though, he is surrounded by cat lovers: his family, his estranged childhood friend, and even his crush Kaede Mizuno. One day, while returning home from school, Junpei nonchalantly attempts to kick an empty can into the trash, but miserably misses. Instead of making it to the garbage, the can ends up breaking off the head...
A cat‑cursed teen must do a hundred feline favors or become the very creature he despises.
Junpei Kousaka is a sophomore who swears off felines after a childhood allergy turned him into a cat‑phobic wreck. Yet his home is a feline sanctuary: his mother adores cats, his childhood friend Natsuki runs a cat‑café, and his crush Kaede constantly drops cat‑themed gifts. The irony peaks one rainy afternoon when Junpei, trying to flick an empty can into a trash bin, misfires and shatters the head of a stone cat deity perched on his doorstep. The broken statue curses him with the uncanny ability to hear cats speak, but the gift comes with a deadly catch—anyone who discovers his secret will be plagued by clumsy mishaps and share the same fate. Guided by Nyamsus, a sardonic, self‑appointed cat spirit who lives in his pocket, Junpei is forced into a bizarre quest: perform a hundred good deeds for cats or be transformed into one himself, a prospect that would be fatal given his severe allergy. Each episode spirals into a slapstick series of cat‑centric errands—rescuing strays, settling feline feuds, and navigating the chaotic love polygon that surrounds him—while he desperately tries to keep his newfound chatter hidden from humans. The series blends frantic comedy, light romance, and a sprinkle of supernatural mischief, turning an ordinary high‑school life into a cat‑filled roller coaster of laughs and awkward heartbeats.
