This February, the Naruto Shippuden anime presents some original back-story material in "Kakashi: Shadow of the ANBU Black Ops." Discussing this on Twitter, director Hayato Date told a fan that the plan is to the return to manga's source material after the story, and possibly run with that for most of the rest of the year.
The manga is currently 56 chapters ahead of the anime.
In a message for TV Tokyo's Sakiyomi Jan Bang! Shonen Jump variety show, manga author Masashi Kishimoto more than hinted that he's getting ready to wrap things up for everyone's favorite orange clad ninja.
