The joke is that a broken air conditioner remote spirals into the apocalypse, and somehow the show makes you believe it completely. Ozu's chaos in a time loop isn't just funny, it's the only logical outcome of giving that man access to causality itself. Every frame moves like watercolor on speed, and the comedy lands harder because the visuals never stop playing along with the absurdity.

On a sweltering August day in Kyoto, a student's plans to cool off are ruined when his trouble-making friend Ozu spills cola on the remote for the boarding house's only air conditioner. Facing the rest of the summer in brutal heat, the students then see a time machine turn up, carrying a scruffy young man from 25 years in the future. The plan seems simple: go back one day, grab the remote before it breaks, and restore comfortable living. Everything falls apart once Ozu starts meddling with past events, and his tampering threatens to wreck the entire universe. The protagonist is left dashing between days to head off catastrophe in this six-episode mix of comedy, romance, mystery and science fiction, a spin-off of Yojouhan Shinwa Taikei.
