Complete Monster: Hikaru Kageno and his father Kenzan, the heir and head, respectively, of Kageno Steel Manufacturing, seek to destroy Japan and remake it In Their Own Image. To this end, they kidnap young women and brutally train them to become geisha assassins, converting them into cyborgs and Tengu servants, while forcing those who leave to commit hara-kiri. They send the geishas out to murder whomever gets in their way. When heroine Yoshie plans to take the Kagenos down, Hikaru leads her into a trap that blows her up, forcing her sister Kikue to watch. Hikaru later rewires Kikue into obeying him, removing her memories of Yoshie. The Kagenos later summon an interest group searching for the women to their building, where they proceed to murder all but three members. Desiring to drop a special bomb onto Mt. Fuji to eradicate everyone in Japan, Kenzan has his building transform into a giant robot, murdering everyone in its way. With Kenzan soon perishing, Hikaru decides to carry out the plan, hoping to kill himself along with everyone in Japan, having Yoshie fight her brainwashed sister as a distraction.
Iron Woobie: Yoshie - even prior to her mechanical transformation. She is able to take multiple punches to the stomach, chest and windpipe from Kikuyakko, and doesn't have any noticeable damage to show for it.
Moral Event Horizon: If Hikaru (plus his father) didn't cross it when he sets up a trap for Yoshie, hoping it will get her killed and forces Kikuyakko to watch the whole thing, then he certainly crosses it when he brainwashes Kikuyakko.
Quirky Work: It's very Japanese, between its martial arts, geishas, and such. And as weird as possible given the robots and over-the-top violence.
So Bad, It's Good: Very likely intentional. With a title like RoboGeisha, it didn't really stand a chance of being anything else. Cue hilarious over the top anime stereotypes and a Narmy voiced trailer bellowing the words "FRIED SHRIMP" as one of its announcements.
