No, but you cna create your own version own naruto where Sakura has a little borther if you want. Even thogh she doesn't it would be cool. Sorry:(
Nope.It was informed that Sakura was an only child.
No!!!! Sakura loved Sasuke not his brother Itachi!
NO....mostly not........b'coz sakura likes naruto more like a brother.......
a little perhaps
no
they meet in the academy when they were little
NO they are not. It may be a fun idea for a fanfiction but Pein and Sakura are not brother and Sister, if they were because you are either born with Rinnegan or earn it from many years of eteranl Mangekyo Sharingan, she would also most likely have the Rinnegan, or at least stick around Pein.
Sasuke is naruto's rival, Sakura's crush, Kakashi's student and Itachi's brother.
The little brother is Doodle.
'little brother' = hermanito
Well Sasuke doesn't have any feelings for anyone since his parents died but he does have a little feeling for Sakura
Are you sure it was Sakura or Sasuke. Sakura was never bitten, mostly because she is not a worthy vessel for Orochimaru. Sasuke was bitten because back when Orochimaru was in the Akatsuki he tried to get Itachi's sharingan but it didn't work, so he went after Itachi's younger brother, Sasuke.
