Sakurasou Haruno

Hey, you all might know my sister, Sakura Haruno? Yeah, the one on team 7. That's the one. Well, I'm her younger twin sister, as the title might suggest, I am Sakurasou Haruno.
The only difference between my sister and myself is that she went to the Academy to train to be a ninja, but I train silently behind everyone's back.
People usually suspects that I wouldn't become a ninja, just 'cause I'm mentally unstable and physically ill? Yeah, good luck with stoping me.
Agh! Sorry! I haven't introduced myself properly! Gomen'nasai!!
*Cough*
My name is Sakurasou Haruno, younger twin of Sakura Haruno. I'm 12 years old and have been training to be a ninja in secret. Reason being because I never really liked being around others but I could be around Ino, as long as she doesn't think I'm Sakura again. Sure me and Sakura look identical, we're identical twins, but we have our differences. I know of one obvious one, my hair is always up in a high ponytail and turns lighter or darker depending on the lighting.
