The only instance where anime is darker than Manga

[SenseiSama]

If it didn't happen in the manga then it's filler.

Wrong, Sasuke's use of Deva in the manga is canon because he used Deva in the manga, he witnessed Madara use the feats SP gave him and manga fact says Rinnegan users can use the feat.


If the 'filler' content is in a scene that has happened in the manga then it should still be considered canon, little details like feats do not matter when they do not contradict the canon lore.
