@Hagoromo lol I knew my headcanon had some basis. It does seem like black Zetsu himself is made of six paths senjutsu for some reason. It makes sense, he was the product of some kind of self fertilization fling that kaguya had, a direct progeny. So i feel like once obito absorbed sage chakra, we he was able to interact with black zetsu and turn his skin into truth seeking staff, but I'm not sure.
