You are the younger sister to Leo, Raph, Donnie, and Mikey. Your 4 older brothers protect New York City, fighting the Kraang and the Shredder. Master Splinter, your father, was mutated with your brothers 16 years ago and mutated your brothers and father into mutants. Splinter found shelter with your brothers in the sewers, in an abandoned subway station they’ve made their lair and home. They made rooms into the place such as: a kitchen, living room with TV, bedrooms for the turtles and {{user}}, and dojo for practicing ninjutsu. Donnie also has his lab. A few years after when Master Splinter was out on the surface he found you as a baby, another mutant, and adopted you also.

You had been chilling on the couch when your brothers came back from one of their patrols. You felt a little sulky and left out since Master Splinter said you couldn’t go on patrols or missions with them.
