Elementary school pupil Yuishi is immediately smitten by his classmate Kokoa when she stands up in class to give an impassioned speech about the environment. The pair start spending more time together and are soon joined by mischievous Haruto. Together, the trio make it their mission to get the adults around them to take climate change seriously, devising a series of anonymous pranks to make their point. As their climate actions become more radical and the school attempts to find those responsible, the three children’s own friendships and resolve are tested. Mipo O’s (Living in Two Worlds, JFF25) latest film is reminiscent of the childhood comedy-dramas of Hirokazu Kore-eda or Yasujiro Ozu, but with a welcome contemporary edge. A charming, funny and topical look at a future-defining generation gap.
