Kishi hasn't even adressed the timeline yet, how can you be upset?
Edit: the only timeline mistake I saw was the minatos face on the mountain in the obito flashback.
you know more about naruto than Kishi?
Kishi knows how naruto ends do you? can you even handle it?
What about him forgetting that Kakashi became a Chunin at 6, and that Hayate was 3 years younger than Kakashi yet he was at the same exam?
Are you buying the Naruto Manga? If yes, then you have every right to complain, if not then you know where I'm getting at.
I do buy them actually. I have a collection.
