so, there is a kaguya clan and there is a hogoromo clan, is there a hamura clan as well? in this chapter we can clearly see that the kaguya clan is related to her in just more than their name as we see her use bone techniques. not to mention that their clan symbol and kimimaro himself, have the same circles as she does. we only see the hogoromo clan once, and it was just a dead shinobi, so we know nothing about them. but i'll wager that they are related to hogoromo as well. so going off that, there should be a hamura clan as well.
