A lost kitten becomes a family by accident, and the show spends 104 episodes proving that's enough. Chi doesn't learn lessons or overcome obstacles, she just exists in a home, scratching furniture and demanding food and sleeping in weird positions, and somehow that's everything. You watch a real cat become real to people, one small, unremarkable moment at a time.

A curious kitten named Chi gets separated from her mother and siblings while out on a walk one day. Lost and alone, she is found by a young boy named Youhei and his mother, who bring her home. One problem: their apartment complex does not allow pets. The family tries to find Chi a new home, but it proves harder than expected, and they eventually decide to keep her and give her a name. Chi still longs to find her way back to her mother. Told in short episodes, this gentle slice-of-life comedy follows the everyday life of Chi and her family, along with the friends they make along the way.
