The year is 2027 in MegaTokyo, six years before the Knight Sabers will make their debut. Boomers (artificial humans) are still a relatively new advancement, and the implementation and integration of boomers into society is still a bit buggy -- sometimes fatally so. Whenever a boomer incident occurs, though, there is the Advanced Police, a special force trained to deal with boomer crimes.

Leon McNichol is a rookie in the AD Police, and is just starting to become exposed to the horrors and tragedies one finds every day in MegaTokyo. He and his veteran partner, Gina Marceau, slowly learn about the ever-fading line that separates man from machine.

Set a few years before Bubblegum Crisis Tokyo 2040, A.D. Police chronicles the tales of Mega-Tokyo's special police division designed to control rogue Boomers in the city. A.D. Police Officer Kenji Sasaki faces a major dilemma: he loses another partner to a rabid boomer. A day after he's sent off-duty, he receives a new partner in the form of German cop Hans Kleif. Funny thing is that Kenji sucker-punched Hans at a bar the night before. Not only does Kenji face the everyday task of controlling Boomers, he has to learn to adjust with his new partner. 

A secret unit of the AD Police, known as Branch, specializes in crimes involving humanoid robots called 'Boomers'. Branch officer Buzz must cope with having a Boomer for a partner, while officer Michaelson finds the line between human and robot to be a thin one. Together they serve to protect a world that is slowly deconstructing around them. Set in the Bubblegum Crisis universe.
