Vladosaurus wrote: Naruto was able to use the TB abilities IE their kekkei genkai, because as stated, SPSM grants him "the innate ability to grasp nature of chakra and comprehend all universal things" Each time he uses a KKG he names the biju, who then responds. This implies it's the biju that does the nature transform. E.g. with Magnet Release Rasengan, Shukaku says "use my chakra then, i'll put a sealing jutsu in it". With Lava Release, he says "Son, lend me your chakra".
