Kill La Kill she also gains cat ears around the end of that anime in her super battle outfit I dont think this is a OC isnt OC's Consider new created chaters? its a really great art but looks like Ryūko Matoi from Kill la Kill.. The outfits really good and writing on her is cool idea also the fact she is chained up. BUT I gave a low rating cause this is not scarlet this is just Search Results
Ryūko Matoi from anime kill la kill ..
