A thunderstorm forces two kittens out of the sky and into a stranger's house, but the movie never treats this as crisis. It treats it as an invitation. This is animation that moves at the speed of curiosity, where a crash landing becomes the beginning of something small and genuine. No spectacle, no stakes that matter beyond what two cats feel in the moment.

Nini and Nene are twin kittens who travel in a balloon ship, and today they are out on another cheerful adventure. A sudden thunderstorm changes their plans: lightning hits the balloon and brings it down. The pair come to rest on a large cloud and head into a house close by, hoping someone can help them. There they meet a mysterious girl. The film is a 2025 graduate work from the animation department of the Tokyo University of the Arts Graduate School of Film and New Media.
