From Tokyopop:

K�an agile mech pilot in Neo Seoul police's high-speed mobile unit�specializes in chasing down and eradicating terrorists. His duty has always been to protect the citizens, and he's given little thought to the mega-corporations that run the city.

But when an ordinary arrest explodes into a nightmarish battle, K is painfully forced to question his convictions. Stripped of all sense of right and wrong, K must make a terrible choice�either join his enemies, or lose all sense of justice!
