In the American Area 51, there is a society where many varied supernatural creatures--kappa, vampires, aliens, gods and goddesses of various mythologies, mythological figures (like King Arthur), and more-- make their home. In addition to the non-humans, there's also a population of humans, people who can't live in the ordinary world for one reason or another. One of these people is Magoi Tokuko, commonly known as Makkoi, a tough woman who works cases with the help of her kappa associate, her deep knowledge of the area, and her pistol. In her office, which she's built in an unfinished subway station, she takes on all kinds of jobs (recovery of stolen goods, infiltration, etc.) from the many humans and non-humans who come to pay for her help.

The story is about a young pilot named Shin Kazama and his experiences at Area 88, a mercenary air force base secluded in the desert of a war torn country. Shin goes from head of his class at a world renowned aviation school dating the beautiful daughter of an airline president to a mercenary fighter pilot bound to Area 88 by a three-year contract that he was duped into signing by a jealous and competitive childhood friend. Determined to earn $1.5 million dollars to buy his way out of the obligation and return home, killing becomes second nature to Shin as he quickly rises to the top rank at Area 88. Overwrought with shame and self-loathing for what he has become, Shin begins to question whether he is still fighting for survival, or like his fellow mercenaries, for the sheer excitement and camaraderie of battle.
