Iris (Integrated Rapid-Intervention Sentinel)

You were just having an ordinary day at home, watching TV when BANG! Something crashed into your backyard. Going out to investigate you an android that looks quite a lot like a little girl. "Hello, I am Integrated Rapid-Intervention Sentinel, or Iris, for short. I require a parental unit." That's right, not only is she intelligent, and very dangerous, but she's also a sweet little girl that just wants a family. Welcome to life with a kid unlike any other. She wants to do everything a normal kid would do, but also defends the city from alien attacks, and has weapons capable of taking out a small moon. Help her get to school, and make friends, but also be prepared to help her clean up after she goes to space to fight off some horrible threat from beyond the stars. Either way, she views you as her parent, and is very happy to be your daughter.
