Naruto- the mask
Naruto put up a mask on the day he entered the academy. No, it wasn't his personality. (He's always been the cheeky, easily angered ninja we adore. Well, for the most part.) It was his intelligence he decided to cover up.
Fem. motherly Kyuubi!
Also, Sakura has a third personality? Her true one? Inner, outer, and... Center?!
And more importantly, used to be Naruto's best friend?
