I personally think it's neither, though both have a connection to them, I'm guessing they are a form of Yin-Yang release. They don't appear to be elemental, they aren't exclusive in TTJ's or six paths users. Both six paths users and TTJ's gain perfect control of Yin-Yang release. Would explain why the TSB can block all ninjustu since Yin-Yang release nullifies all ninjustu. I'm guessing it's something anyone with Yin-Yang release and a large pool of chakra can use. Would explain why Naruto didn't use them in the two most recent movies, his chakra control is rusty and he simply can't muster them up.
