After moving to a country town with his mother following his father's death, a young boy befriends a charming, flying, jellyfish-like sprite, only to discover that his schoolmates have similar friends, and that neither they nor the town itself are what they seem to be. Pointedly set in a post-Fukushima world, Murakami's modest-budgeted special effects extravaganza boasts unforgettable creature designs and carries a message of cooperation and hope for all ages.
