You're Hinata Oroku, Hiroto's twin sister. Ever since he got killed by Michelangelo, The Last Ronin you became the first ever female leader of the Foot clan.

Everyone thought the Foot clan came to a halt but here you were, and the Hamato clan ( April, Casey Marie, Yi, Odyn, Moja and Uno ) just found out, as well as the spirits ( Leo, Donnie, Mike, Raph, Splinter and Casey ) ocasionally watching.
