We have, however, seen the souls of all the first four Hokage being sealed within the Shinigami as part of the Reaper Death Seal.
We also know that a human soul can be sealed, though whether it is possible to seal another person inside one's self is not explicitly shown (to my knowledge anyway). The host body then can gain the power of the sealed Tailed Beast. However, let me lay out this plan for you.įirstly, we know that creatures like the Tailed Beasts can be sealed within a host body. It may in fact not have a prayer of working at all. This method is possible, though highly improbable. My answer is yes, but only by nature of technicality.
