When you were young you knew this girl, Jessica, well, you more than knew her, you were lovers. When she started experiencing symptoms of mutation, you were overjoyed! To be romantically involved with a anthro super hero! Oh to wonder which creature she would become, only for your dream to be crushed.
As you entered her house, it was ransacked and deathly quiet, you rushed through the house only to find Jessica on the couch, but fully mutated. She turned into some sort of shark woman, you didn't even know that was possible, but when she turned to you it was even more shocking. Her belly had outlines of what seemed to be 3 other people. They still struggle within her belly, she must have swallowed them whole and alive, it looks horrible.
You were brought back to your senses by the deep rumble of Jessica's belly, she wasn't finished yet. She lunged at you, eyes pitch white, but as soon as she tackled you to the ground, they filled to be dark black, like a shark's would. Your head was soon engulfed, but before you could be swallowed further, everything fades to black.
You wake up in a dim room, only with a man in black gear and shades sitting in front of you, his shoulder reads: SPFA. He explains the situation, Jessica was showing signs of mutation from their scanners, and they watched closely to see what would happen. When she mutated into a "dangerous creature", they detained her before she could harm anyone else.
You: "What about her family?!"
Him: "No others could be saved."
You stare solemnly into his eyes, and ask him if Jessica regained her sanity. The man explains that all anthros regain sanity soon, but only time will tell if they lose it again, which is why Jessica must be contained. Before you can ask, he explains that the facility of containment is top secret, but since you now know about the SPFA, you cannot be let out of there sight unless trusted. So, they tell you that you must work as a secret operative until further notice, working as an IT person at a school for anthro super persons, which were deemed "Non-dangerous creatures" by the SFPA. It is your job to determine if any of the students may end up becoming dangerous in the future.
You: "If I refuse?"
Him: "Then you will work at the holding facility, but be warned, as a non-aanthro person working as a guard in a facility holding many super-powered anthros, most of which who want to eat you, will not go well."
You take the first option, your work as the IT person at a anthro super person's school for making them superhero's starts tomorrow. But as you let the news run while you try to sleep, you hear that the facility had a minor break out, and a few anthro super persons escaped... whereabouts unknown...
