Do you have to watch the anime only arcs of Naruto Shippuden?

The anime-only arcs of Naruto Shippuden are not necessary to watch in order to understand the main storyline of the series. These arcs do not contribute directly to the main plot, and they do not affect the overall development of the characters. However, they can provide additional context and character development, and they can be enjoyable to watch for fans of the series.

If you are looking for a complete and comprehensive experience of Naruto Shippuden, then it is recommended to watch both the manga and anime-canon arcs. However, if you are short on time or if you are only interested in the main storyline, then you can skip the anime-only arcs without missing out on any essential information.
