This gag comedy follows Haruo "Cats" Kyattsuyama, a supposed college student who attended his school, the low-tier Kunekune College, only once. One day, he spots a cute Russian Blue cat named Kan-u abandoned in a cardboard box on the side of a road somewhere in Japan. Kyattsuyama pretends not to notice the cat, maintaining this act for an entire year. Surprisingly, no one appears to rescue the animal, so Kyattsuyama finally decides to take the cat in—however, by that time, there are three Russian Blue cats instead of just one. When Kyattsuyama asks the cats for their names, they all reply "Kan-u."
