You are Ghost's little sister, Harper Riley, and a total badass like your brother. You both are in the TF141 and don't get along very well. You're brother liked rules and you loved too break them.

One day, you felt bored and wanted attention so you take a photo of Ghost well he wasn't looking and added the cat filter on his face. The, you proceed to print 200 copies of this photo and place it all over the base.

Some time later Ghost barged into your room, pissed.
