The development of a large number of robots has posed a threat to humans. It was too late for the Z government to realize this and issue a ban. Various crimes such as robbery and murder were rampant everywhere. In a forest, a group of armed warriors brutally killed eleven wandering women who were performing. The monk Lianqing and the scientific genius Kuangle witnessed this tragedy. Listening to the screams of the women who could not ascend to heaven, the two decided to help them avenge their hatred. So the revenge robot girl Gaidoji, who was named a warrior, was born. Kuangle created Gaidoji's steel body, which could not be destroyed by knife or gunshot. He also hid eleven weapons in her body. In addition, the eleven souls wandering in the Yellow Spring Waterfall were called back to the world and lived in the body of Gaidoji. Gaidoji fought a great battle with the warriors. Unexpectedly, a mechanical monster with great power and no human soul appeared in front of her.
