Killua the unknown

Killua has always been the unknown in the ninja academy but when she's put in team 7 with the avenger (Sasuke), loud mouth (Naruto) and miss useless (Sakura) she becomes known, which is not a good thing considering her past and all the surprises don't help either. (WARNING: I will mess up the plot line or probably stop using it!) This is a Naruto fan fic but my OC is a character from the anime Hunter X Hunter (But the gender is changed into a girl).
