Does the information about Hamura and Toneri using natural energy/senjutsu come from The Last itself (haven't seen it yet), or is it from the novel and/or guidebook? If they really are senjutsu users, that seems to pretty much confirm that the Truth-Seeking Balls require Six Paths Senjutsu or an equivalent power. Presumably the reason they weren't classified as senjutsu in Jin no Sho is that Kaguya can use them (or at least their advanced form), and her power is not senjutsu but not natural energy itself or some such.
