In 20XX, Tokyo fell under the control of the evil organization Vodka, and government institutions collapsed into dysfunction. Citizens lived in constant fear. To combat Vodka's tyranny, Dr. Kosaka, a leading expert in cyborg research, began developing a female cyborg at the government's request. However, Vodka would not allow this research to continue and suddenly raided Dr. Kosaka's laboratory. At the time of the attack, Dr. Kosaka was away and survived unharmed, but his assistant Tanaka was killed and his wife, Anri, suffered severe injuries. As time passed and Vodka's soldiers ran rampant, the female cyborg finally emerged. Yet, her appearance would lead to an unexpected and tragic outcome.
