Shin Kazama has a bright future. He is an up and coming pilot for Yamato Air Lines. He has a relationship with the boss's daughter, and perhaps is destined to head the airline. All this changes when his friend Kanzaki gets him drunk, and Shin signs a paper which enlists him in the Aslam Foreign Legion. There are 3 ways to get out: to get enough kills to buy your way out, to survive until your term is up, or escape. This is a gritty, action-oriented series with accurate depictions of military aircraft and associated hardware.
