Sakura: no longer can i sit and be useless, thats it! ive got to help!
im going to go fight!
*runs onto battlefield and a friendly kunai is accidentally thrown at her..
"accidentally"
*sigh*
Sakura has shown that she can be helpful, but blame kishi for not giving her any fights. But then again, fights are the only things that Naruto fans think make a person useful so I'll just leave this alone.
A character I don't want to see pissed off is probably Nagato.
