From the creators of SPRIGGAN comes a new tale of nano-machines, cybernetic assassins, powerful telekinetic opponents, and a secret organization dedicated to bring forth the next evolution of man. Ryo Takatsuki thought of himself as just an average high school student, until he learned that his arm had been secretly replaced with a powerful nano-machine driven weapon called “ARMS.” Designed to be the ultimate integrated weaponry, ARMS is insanely powerful and, in inexperienced hands, can often go out of control. Now a powerful, secret organization is after the only living samples of this technology, and the strangely enhanced assassins who are sent to get them are ready to kill anyone who gets in their way. As a result, Ryo is quickly ripped from his ordinary life into one of mayhem, where he must face those who try to obtain his power by any means possible.
Ryo Takatsuki is about to have his world come crashing down. It all starts when a new transfer student threatens to kill Ryo for seemingly no reason at all. The trouble escalates as a group of black-suited thugs show up to harass Ryo, but he manages to escape thanks to his survival training. Do either of these mysterious incidents have to do with his right arm that, since an operation in kindergarten, has been able to heal at a miraculous rate?<br />
