When I was ten, I liked the Sailor Senshi a lot. I was in love with Sailor Pluto, the darkest, coolest one.
Months later I started feeling slightly disappointed with their fighting skills. I had discovered The Rose of Versailles and Ranma 1/2.
At age of twelve, I had created my own (not-so) magic girls. They were real warriors from a medieval/steampunk world, users of hand weapons that travelled through a multidimensional universe chasing down a weird predator that destroyed their whole homeland.
Unfortunately, the monster couldn't be killed.
The story had a happy ending anyway. After years of hunting, the girls - that were not the only ones going after the creature - met some scientists that happened to have developed a suppressant able to make the predator perfectly docile.
Scientists and warriors teamed up together, captured the beast, and sent it to sleep.
Things would have stayed like that forever, if it wasn't for a small but relevant detail: in order to keep the monster in the sedated state, the treatment needs to be repeated at regular intervals. Which means that someone has to produce more drug, and to inject it, and to monitor "patient's" conditions, and to enforce security measures. And to find the money, that is, people willing to pay, or perhaps...
