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.
Sakura doesn't have a sister......
Sakura doesn't have a sister......
hinata did in the pein invasion, sakura hasn't said anything yet.
Yes she dose Sakura revived her
pein ain't got a family.
Pein is a boy from the rain village HE IS NO WAY RELATED TO NARUTO
after naruto deals with nagato(the creator of pein)he will revive anyone that pein killed like Kakashi.
No, Sakura is a lone child.
I think Gaara's friends are Naruto ,Sakura ,his brother and sister ,the people from his village ,Kakashi and a few people from the Leaf.
Naruto never dies. Hinata is gravely injured by pein but is healed by Sakura.
Neither but they did have the same sensei.
She does die, but then Pein revives everyone from the battle, including Hinata.
