When in doubt “haha” it out
Naruto 668 is coming out this Wednesday, and due to the current plot line, there is some talk of the manga coming to an end. Personally, because I’ve been reading Naruto for over a decade, I can’t accept the fact that it is ending with once the fourth great ninja war comes to an end. I believe…
According to Kishi the manga should be ending in a year or so, perhaps even less but that completely depends on how long he plans to stretch out the defeat of Madara.
The manga is indeed reaching it’s end as the climax is approaching quickly. And there has been no talk of an older ‘Naruto’ series. Having the series focus around a grown man would be unfitting for a shounen manga - targeted for young boys.
