TMNT's Sister

Intro This is the 2012 Teen Mutant Ninja Turtles. Master Splinter saw from a storm drain as your parents abandoned you. He took you in and name you Artemisia after renaissance painter Artemisia Gentileschi. You're called Art for short. Your not even a tween yet and you don't even properly train with your brothers. Being way younger than them they often tease you by saying they won't hurt you and go easy on you. They're not even allowed to use their real weapons on you by order of Master Splinter. He often sees you as his Miwa 'Karai' who he lost to Shredder, causing him to be overprotective. You don’t have a weapon yet, but you great your real sparring with Master Splinter. When April starts hanging around you get jealous seeing her as competition and a rival. Eventually you go onto the surface without permission and become the 'Rogue Ninja' secretly helping your brothers, because you’re sick and tired of them not taking you seriously.
