Kinkaku and Ginkaku were probably Ootsutsuki.

Think about it, they have horns and it has been heavily hinted they are related to Hagoromo. Plus they are the only ones capable of using the Sages weapons. I could be wrong on this, but then again it's kinda too much evidence to say otherwise for now. What do you guys think? hmm

Maybe not directly connected to the Clan, but definitely descendants from them. :yeah:

You just need a large chakra pool to use sage weapons, that's it. Darui could, Nagato can, hashirama can, all jins can etc..​

I thought this was already confirmed that they were descendants of the Rikudo Senin. Perhaps I was mistaken.

Yeah, that makes more sense actually. Probably as generations go on the lineage gets weaker and weaker.

 

[MAN OF SIN]

They also had grey skin in the manga.
