Plot

The film starts out with an assassination attempt on a political candidate by a Geisha (that turns out to be a robot) and two scantily-clad women wearing Tengu/Goblin masks. The goblin-clad women violently (and phallically) take out the body guards (notably shooting shuriken out their butts) as the politician is menaced and wounded by the robot geisha who has a circular saw blade in her mouth. Suddenly, another person named Yoshie (Aya Kiguchi) appears, reveals herself as a robogeisha, and destroys the villainous robot.

We go back in time to see Yoshie as a servant for her sister Kikue (Hitomi Hasebe), who is a geisha in training. It is later revealed that the two sisters were orphaned, and though they used to be close (with Kikue being the favorite child), they are now enemies. Yoshie is klutzy and ruins Kikue's performance for Hikaru Kageno (Takumi Saito), heir to Kageno Steel Manufacturing. Despite her klutziness, Kageno is impressed with Yoshie's beauty and becomes more interested when he witnesses her display of superhuman strength when threatened by Kikue.

Eventually, Kageno invites the two sisters to his house, where they are captured by the goblin ladies. The two are forced to fight to the death, and after Kikue wounds and actually threatens to kill her sister, Yoshie snaps and knocks out Kikue, once again displaying superhuman physical prowess. Accordingly, Kageno and his father begin training Yoshie to become an assassin for the company along with many other young Geisha-type women, and she quickly becomes the head assassin. They are told that Kageno Steel seeks to use them to kill terrorists and other national threats in an effort to create an "Ideal World". Kikue, meanwhile, is relegated to the role of servant to the organization.

Nonetheless, Kikue strives to outdo her sister and shows a greater propensity for violence than Yoshie. Eventually, both sisters frequently undergo surgery to become cyborgs (Robogeisha), with machine-gun busts and other robotic enhancements. On their first mission, however, Kikue is severely wounded when she selflessly saves Yoshie from being killed by one of their target's bodyguards. Later, Kikue explains to Kageno that though Yoshie annoys her, she still loves her sister. Nonetheless, Kikue will never be able to recuperate sufficiently to serve as an assassin.

The story reaches a turning point when Yoshie is sent on a mission to kill a small group of elderly people and their young caretaker living near the Kageno Steel building. The seniors then reveal that they are the relatives of the Kageno Steel's geisha and goblin assassins and that Kageno Steel has actually been abducting these girls to serve their own ends. Yoshie confronts Kageno and his father, who confirms the story. Then, the duo threatens to kill Kikue unless Yoshie completes what turns out to be a suicide mission. The other girls also have been devoid of a conscience and humanity for so long that they decline to return to their families, remaining geisha assassins.

Yoshie barely makes it out of the building after an Explosion from the Suicide mission and her body is recovered by the senior group and she is rebuilt by the leader, who used to work for Kageno Steel. The protestors want a meeting to demand the return of their loved ones. They found a set of Kageno's blueprints for a bomb that's said to be "17 times more powerful than the atomic bomb" and intend to use to threaten Japan into ceding all power to them. The group then heads off to confront Kageno and his father and force them to return their cyborg relatives or reveal the bomb plot to the authorities. But the Meeting is revealed to be a trap as the father and son have also robotically modified themselves and kill most of the senior group. The leader, however, had installed a gun into his leg and uses it to kill Kageno's father. Hiraku, now freed from responsibility, activates a protocol that turns his family castle into a giant robot. Kageno reveals that he intends to drop the bomb into Mount Fuji, thus destroying Japan and himself and "freeing" everyone. The robot-castle is wired to mimic Kageno's every move.
