The teaser visual shows the brothers Mutta and and Hibito during childhood. The trailer then proclaims that "the previously unwritten true beginning of that manga, which embodies Japan in dreams and emotions, is being made into an animation film. This is the origin story. This is chapter 0."
The Uchū Kyōdai #0 (Space Brothers #0) film will open on August 9. The original manga has been on hiatus since December 26 because Koyama was writing the film's script. However, he will resume the manga in this year's 12th issue of Kodansha's Morning magazine on February 20.
