Shiro Lhadatt wanted to fly jets for the Kingdom of Honneamise's Air Force when he was young, but unfortunately he didn't get the grades he needed; instead, he enlisted in the Space Force, a tiny embryonic unit that most people haven't even heard of. Embittered and disillusioned about his lot in life, Shiro takes no interest in his training - that is, until he meets and gets to know a young woman preaching God's word on the city streets. After one inspiring conversation with her, Shiro promptly sees the light; he finds his passion for flight reinvigorated and immediately volunteers to be the pilot for his unit's first space warship! Reaching that new frontier is all well and good but Shiro still faces some major obstacles: even if launching the first space warship becomes reality, not everyone will be happy to see the Space Force succeed. Suddenly, Shiro has to grapple with the complex, far-ranging consequences of his very personal decision.
