- Complete Monster: Tokyo's police chief is a vicious Knight Templar who despises Engineers, despite being indirectly responsible for their creation. Doing whatever he can to keep the police privatized, he orders the assassination of Ruka's father for holding a rally against said privatization, immediately killing the assassin—Key Man's father—afterwards, later taking in Ruka as his own and training her to become the ultimate Engineer killer. He keeps a limbless woman as a pet, using her primarily for sex and violence. Witnessing the Key Man turn one of his men into an Engineer, the Chief orders a violent city-wide crackdown on possible Engineers, gleefully watching as psychotic policemen brutally slaughter both Engineer and human alike. Discovering that Ruka's now an Engineer, the Chief considers her a traitor and tries to kill her.
- Crosses the Line Twice: The entire movie crosses the line 9 times and just keeps on going. It almost feels less like a movie and more like a movie-shaped Aristocrats joke.
- Magnificent Bastard: The Key Man is an elusive criminal scientist who created the Engineers. After witnessing his fathers assassination, the Key Man discovered the tumor used to turn people into Engineers after a failed suicide attempt. Planning to turn everybody in Tokyo into Engineers to control the city and avenge his father, the Key Man goes around town killing prostitutes and turning people into Engineers, while able to remain hidden and undiscovered by the police, at one point turning officer Ruka into an Engineer. Politely inviting Ruka into his hideout after she discovers it, the Key Man is killed by Ruka after trying to persuade her into joining his Engineer army, but repairs himself afterwards, ready to continue his plans for domination.
- Narm Charm: The infamous shotgun penis. It's pretty clear from the facial expression that the actor played the Engineer possessing it was trying his damnedest not to burst out laughing because of the ridiculousness (no pun intended).
- Nightmare Fuel: When the police declare martial law and start a brutal massacre of everyone they see.
- Retroactive Recognition: Ayano Yamamoto, which is known as Super Sonico's voice actress nowadays, has a minimal role here.
- So Bad, It's Good: Probably intentional. The Gorn is so over-the-top, the plot is so ridiculous, and the High-Pressure Blood in it is taken to such absurd extremes that there's no way the director and actors were taking it very seriously. Either way, this film manages to cross the line twice.
- Special Effect Failure: The wristcutting scene during Ruka's introduction features an obvious dummy arm with overly pink skin compared to Eihi Shiina's pale complexion. Thankfully, future movies by this director have perfected this effect.
- Visual Effects of Awesome: The Vagina Dentata example, the bit where Ruka's arm bursts open as the villain forces her to become an Engineer, and the bit towards the end where a cop shoots Ruka in the eye and it visibly grows back.
