Why do you hate manga facts?Like it or not, but the new heroine of the series is none other than Sarada and calling her possible future abilities a "fanfic" is nothing else but an ignorance. The sooner you accept that Himawari will be just a secondary character with no bigger importance in the series then better for you. Or you can still whine over her "defeating" Naruto in a comedic one-shot. Your choice, really.
No because that would be fanfic XDYawn, you minus well throw in one ems and one rinnegan too.
