Area 88

Shin Kazama was an airline pilot who was close to marrying Ryoko Tsugumo, the daughter of the CEO of Yamato Airlines. Unfortunately, fate had other plans when his former best friend Satoru Kanzaki tricked him into signing a contract to be a mercenary pilot for the Kingdom of Asran. Now stationed at the Middle Eastern country's base Area 88, Shin has three ways to return to Japan: serve the air force for three years, earn US$1.5 million, or desert the base, facing imminent death.
