I got to say I do agree with Chatte. I feel like the thing is if true about temporary power up, I think Kishi really got himself in a corner to make it work. Like I know people thought Obito will give his eyes to him like physically, but that would make it automatically permanent, thus wear a blindfold for the rest of his life, which would be funny. Anyway, it's like "Well...how can I make it a temporary...I mean I can have Kaguya poke them out by the end but I don't know if I want to do that..." So enter this. I know Kishi tried to explain but it is hard to comprehend it you know. If it's temp, fine but I wish he could have find another way. Maybe Obito truly wanted to say, "Oh kitten! I forgot to make a parallel! I'll be right back," but I digress.
Two notes I should reflect:
1) I have more sources to make fun of Sasuke!
2) Well, now I truly see Sasuke's parallel! It all makes sense in that regard. Not hard to see the joke.
The issue of its permanence isn't the problem. I think it will be easier for people to ignore of the impact is short lived (and limited).
It's real problem is that his acquisition makes no sense and violates the manga's own internal rules. Stories can have people do things that cannot be replicated in real life. Readers can deal with that, so long as the story itself contains rules and explanations on its use and that the author allows themselves to be bound by them. It's harder to deal with it when the author won't even obey his own rules when they are a roadblock.
It would have been better if he actually got the physical eyes and it were permanent. There is at least precedent for that.
his chapter does give me an uncomfortable feeling that a part three might be coming. If Kakashi is going to be the sixth hokage, then it's going to be a while before Naruto becomes the seventh and I always imagined the manga would end with Naruto as the hokage. Of course I could be wrong, but it would seem like a rather big copout not to show Naruto achieving his biggest goal at the end. I really don't want a part three though. The longer this manga goes on, the bigger mess it's likely to become.
I think the Sixth Hokage bit is a token title (what will Tsunade think when she comes out of the pod, cause we know she will). It'll allow Naruto to be the Seventh (Team Seven and all that) and, I think, is supposed to allow Obito to obtain his dream vicariously (which makes me a little ill).
