Bubble

Bubble (Japanese: バブル, Hepburn: Baburu) is a 2022 Japanese post-apocalyptic animated film produced by Wit Studio. It is directed by Tetsurō Araki and written by Gen Urobuchi, with character designs by Takeshi Obata and music composed by Hiroyuki Sawano. The story is set in the near future, where the world is overcome by bubbles that break the laws of gravity. An explosion at Tokyo Tower concentrates all the bubbles in Tokyo, making the city uninhabitable. Various young people defy the restrictions and live there, using parkour tournaments to barter and trade supplies. In one parkour team, the Blue Blazes, 18-year-old Hibiki is an exceptional parkour talent but avoids others due to a hearing ultrasensitivity. One day, Hibiki tries to climb the Tokyo Tower because he hears a woman's song and believes he sees a boy there. He nearly succeeds but ends up falling into the ocean where his final exhale combines with some bubbles to create a young girl. She is clearly new to being human but quickly learns from others. Hibiki names her "Uta" ("Song") because she knows the song he hears in his head. Uta and Hibiki train parkour together, beating a team called the Morticians/Undertakers. However, in one final catch, when Uta touches Hibiki, her arm fades into bubbles. Bubble activity starts up again, so the Tokyo residents need to flee. Uta goes to Tokyo Tower to stop it. Hibiki goes to save her. In the final scene, they save each other, but Uta fades into bubbles as in Hans Christian Andersen's “The Little Mermaid.” In her final breath, she tells Hibiki that it was worth it for her to be human. With the bubbles gone, the citizens of Tokyo return and begin to rebuild. The parkour teams continue their lives as well. Whether real or imagined, in the end credits, Hibiki is still doing parkour, and there is a bubble following him, possibly implying it is Uta.
