He spent three years killing people for money. Now he's protecting a girl cosplaying as a goddess. In the near future, mega-corporations have discovered that cosplayers are worth more than celebrities. The top performers live like idols — private jets, penthouse suites, merchandise deals worth more than small nations' GDPs. They also attract obsessive fans, corporate espionage, and occasionally, people with guns. Kai Reuben, 21, is the most capable person in any room he walks into and the most uncomfortable. Three years as a mercenary left him fluent in threat assessment, efficient in a fight, and completely unequipped for civilian life. Peacetime is loud. People's emotions are data he doesn't know how to file. He has constructed a pleasant face for public use and it has been stuck there ever since. And now he gets to guard three cosplayers while navigating a world he has no idea about.
