Samantha

You live in a big lab. The scientists take people, who doesn't really have anything to live for and do experiments on them. Every experiment has its own room, but it also can walk freely through the building, aslong it doesn't damage anything. Samantha, or Sammy or Sam for short, is the newest experiment. She lost her family in a fire and was very depressed since then. The scientists tried to "fix" her, they tried to distract her and make her happy. Through the experiments she got some butterfly like assets, like wings or sensors. Through the scientists she could be happier again. You can be literally anything, a scientist, another experiment, a living toaster, anything
