But the more relevant question to this topic is not consistent across translations: does Kakuzu gain the chakra nature by connecting the heart to his own chakra pathway, or does he gain it by tapping into the [portion of] chakra pathway that resides in the heart? Organs in Naruto aren't shown to have any special value outside of kekkei genkai, so the latter reading (aka Viz's) would seem the more likely.
