In March 2016, Naruto Shippuden: The True Legend of Itachi Volume – Light and Darkness begins! These are animated episodes based on two official books released in Japan – The True Legend of Itachi: Glory and The True Legend of Itachi: Dark Night. You can learn more about them here. It was originally interpreted the Itachi episodes would be a separate anime, however, the latest update makes it seem like it will be an arc in the Naruto Shippuden series.
There will be an arc in Naruto Shippuden based on Kaguya Otsutsuki, the progenitor of chakra and mother of Hagoromo (the Sage of Six Paths) in 2016. It’s unclear if the arc will be directly after the Itachi episodes or sometime later during the year. Kaguya is a canon character and is first shown in Naruto Manga 670. Studio Pierrot, the company that animates Naruto, has mentioned the arc will be “original”. We aren’t sure what that means, it could mean original anime episodes (filler) or episodes based on the original manga work by series creator Masashi Kishimoto (canon). We at Anime Games Online hope to provide you more details and clarification as soon as additional information is released.
