Still it's a filler, although I must admit that's a nice-made one. It's not based on the manga because there was no mention of Kaguya's background in BZ manga tale, nor that of Hagoromo/Hamura. Even the battle against Kaguya (Ten-Tails) wasn't actually shown, only the outcome was told. In te manga, BZ just spoke about the most significant events and facts in the shinobi history Naruto/Sasuke have never known about (i.e. Kaguya's true nature and manipulations to revive her).
