Machine Girl on AllMovie

A teenage girl shows the mob who's boss in this over-the-top blend of action, horror, and comedy. Ami (Minase Yashiro) is a seemingly ordinary Japanese schoolgirl who refuses to turn a blind eye when thugs at her school subject her little brother to needless cruelty. Ami retaliates against the vicious kids and their folks, which turns out to be a dangerous decision when she discovers some of them are connected to local gangsters. Ami is kidnapped by strong-arm men whose intimidation tactics include cutting off one of her arms, but Ami refuses to let the criminals go unpunished. With the help of a mechanic sympathetic to her cause, Ami's arm is replaced with a high-caliber machine gun, and she is transformed into a single-minded killing machine in a school uniform. Kataude mashin garu (aka The Machine Girl) also stars Asami Kentaro Shimazu and Taro Suwa.
