Well, looks like we were right on the chapter being like bad fanfiction.
Part of me hopes this is some elaborate prank and the official Shonen Jump release will have the actual chapter. But I'm just grasping at straws at this point.
Pairings aside, this chapter doesn't fit Kishi's writing at all, neither does it provide the conclusive ending we were promised. What about bonds? What about Naruto bringing lasting peace to the entire world? It's like someone else wrote this chapter, because this is not the writing I've been enjoying from Kishimoto. I do have to wonder if it was forced and Kishi made it horrible on purpose out of spite.
