Royal Space Force: The Wings of Honnêamise

In this animated film, Shiro (Leo Morimoto) fails to become a navy pilot for the mythical kingdom of Honneamise but is accepted into the Royal Space Force. To keep their funding from being cut off, the agency must make Shiro the first man in space. Shiro befriends Riquinni (Mitsuki Yayoi), a religious fundamentalist opposed to the program. When he discovers the military hopes to use the rocket launch as an aggressive gesture to declare war on Honneamise's neighbors, he questions his assignment.
