This reads very lore-accurate and the dialogue and plot feels like it would've come straight out of a filler arc. This person knows the mechanics of the series and the characters. This is exactly how things would play out if this was canon. That's impressive and admirable but at the same time it's overly dialogue heavy and the text is rather small. This is so lore accurate chapter 4 even has an unnecessary recap. It almost works. If only it just had more emphasis on the growth rather than why the growth happens. If only Hinata got it too. If only it had been finished.
TL;DR This is a lore-accurate Naruto plot first, a FMG comic second.
