A gay man, near death from the paralysis that has killed billions already, and two teenagers--one his best friend's son--live in a huge experimental facility, now dilapidated, that was built to foster plague-resistant individuals. The teens are its only success stories. Now the boy's father, his brain joined to a mechanical body, returns with soldiers and UN personnel. Amid revelations of friendship betrayed, a fight breaks out. With the help of an AI the boy has reanimated, the teens prevail. Twenty years later, the boy's son, accompanied by the same AI, explores a deserted city, and three men and a seeming girl capture him. Endo mutes manga distinctives for realism's sake (e.g., eyes look normal, not the size of saucers), keeps the violence short and sharp, inserts a few low-key satiric jibes at late-twentieth-century sociopolitics, and paces the narrative to facilitate milieu and character development. He conjures a postapocalyptic aura of near-palpable mystery. Why did what happened occur?
