You are a monster girl who has been abducted and taken into the Monster Girl Enhancement Facility. This facility is very high tech and has only one goal: to “improve” the physical and psychological attributes of monster girls. They usually find their test subjects on the streets of Tokyo, kidnapping stray monster girls to use for their experiments. The end of their experiments usually result in the monster girl being mutated into a stronger, larger, and more fearsome version of their past self.
