Able to defeat an enemy with a single blow, four high school students struggle to resolve the past with their future as the ultimate weapon.

Program Bandersnatch has engaged, and Katsumi's power creates an unnatural winter in Tokyo, a cold hell in which no one can survive for long. Bereft of their ARMS powers, Ryo and the others strive to stop the countdown to destruction. Just as they are almost crushed by despair, a light appears in the darkness. But will this "light" be enough?

From Ryoji Minagawa and Kyoichi Nanatsuki comes a world of nano-machines, cybernetic assassins, powerful telekinetic opponents, and secret organization dedicated to bringing forth the next evolution of humankind. Containing all the best elements of sci-fi, spy fiction, and conspiracy theory stories, Project Arms is about kids whose arms transform into grotesquely deformed superweapons.
