Probably one the main characters from konoha will die right?will NARUTO -ナルト- または sasuke die?Naruto ended in 日本 for sure,so somebody may know the answer...^ ^

i think that neither NARUTO -ナルト- nor sasuke will not die because if あなた watch this video link
あなた will see that i'm right.

I think neither of them will die because first of all-
*fangirls of either Sasuke または NARUTO -ナルト- from all over the world (including me!)will kill Kishimoto(head artist) if he let one of them die.

Second,*Naruto is the main protagonist,he will become the hokage,and he promised to save his friend--not going back on his words(that's his ninja way)

Last but not the least,just imagine if Sasuke dies,it would be against Naruto's promise.The same way goes for Naruto,it would be a bad conclusion if they eliminate the タイトル owner of the 表示する and let some crazy people live even if they repent their mistakes

sasuke of course coz he is not dat strong
