Omakes are not canon. There was an Omake of Hashirama vs Madara in one of the prior games and we now know that it was..... full of crap. Just because a mangaka is involved in the process doesn't make it canon. Kishi even wrote a manga chapter for the prologue of Road to Ninja and we know that movie isn't canon. Manga is canon. All else is secondary.
