I'm not sure. In the book of sha, it is said that one needs to know their own "disposition"/"nature" (not elemental nature) (資質, shishitsu).

This might be a biased opinion, but to me all this means that there is one chakra nature a shinobi has a leaning to. This one chakra nature is what the paper reacts to and it is the one that Kakuzu can steal with his technique. While "affinity" probably wasn't used, it's a term that describes it the best, I think. And because of the definition of that term, one can't have more than one affinity. Or how would he be able to lean towards more than one chakra nature? Would the paper crumble and go up in flames? Would Kakuzu need only one heart for two natures?

I'd like to check what the anime said about this, so if someone could find me the episode and the time, that would be swell.
