The chapter was very good and full of suspense. Is it just my feeling, or the manga is indeed moving in a quick pace mode in the past 4 months? (as compared to the first half of 2013)... I might decide to buy the volume again, the last volume that I bought was vol. 63 I think...
I can't help but think that Sakura might get hurt in the next few chapters, hopefully not, but her thoughts regarding Madara seems a bit off and unusual. She never had those thoughts before when she encountered all her previous enemies, if I'm not mistaken.
There's so much possibilities based on the setup that Kishi put in the past few chapters. Using the NS pairing goggle, one can easily see the setup he put on 662 brought us to a solid NS moment in chapter 663. Heck, even the setup on 630 has brought us a nice but impactful girlfriend comment in 631. I'll keep my expectation low as usual... ;)
I personally don't want Naruto to have conversation with someone in limbo. He had conversation in such environment with his father and mother. It should be kept special and exclusive to them, because that really brings his maturity ten folds. Every time I re-read the chapters when he first met his father and subsequently his mother, the outcome of the meeting always gives me a Goosebumps -- one of the most powerful scenes in the manga. Having another conversation in limbo will add nothing to his maturity, only drag the drama. Neji also doesn't seem to fit into that picture, since he dies with no regret and nothing is pending to be concluded between Naruto/Neji. Jiraiya may be a candidate, though seems to be a bit forced -- and it'll belittle Shikamaru's and Iruka's effort to cheer Naruto back then... but again, who am I to challenge Kishi's art work... :)
Overall, nice suspenseful chapter. Thanks Kishi sensei for the good work.
