Caught this as the Asian Film Festival of Dallas. Very fun movie. Best with a group of friends. A lot of Robocop influence with the privatization of the police and the funny TV ads to get you into what the culture in the film's all about. Like designer wrist-cutting blades for girls.

After Ruka sees her father's head blown off by an assassin as a girl, she vows revenge against criminals and joins the police force which has recently become a privatized organization. Engineers are her specialty, called that because if they lose a body part, some weapon or other grows back in its place. As Ruka searches for the root of the engineer menace much bloodshed ensues.

There is indeed much gore here and it's all fun. There's an extended scene here.
