Battling incredible odds and critical public opinion, a trio of astronauts fight to disengage a runaway generator in impossible conditions and silence longtime critics at the same time.

When Asumi was just a baby, Japan’s first manned space rocket, the Lion, malfunctioned and crashed into her hometown of Yuigahama. The impact killed many of the townspeople and critically wounded the girl’s mother, who lay in a coma for several years before passing away, having never regained consciousness. With the help and friendship of Lion-san, a mask-wearing ghost who claims to have come from the rocket, Asumi grew up focusing on her dream – to someday travel to space. Now a young adult, she is determined to beat the odds and attend the newly-formed Tokyo National Space School to achieve her lifelong goal. Alongside Lion-san’s guidance and several new, dear friends, Asumi will try her hardest to touch the stars.
