Is Sesshoumaru immortal?
I don’t think Sesshoumaru is “immortal” as in “unkillable” but I think being a youkai, he is able to live for a very long time. Exactly how much longer than humans, we don’t really know. Although their life span is a little different from your typical human, it doesn’t necessarily mean he can’t die. In fact, Sesshoumaru was almost killed by Inuyasha’s Kaze no Kizu attack but was instead saved by the Tenseiga. So judging from this, I’d say that even though Sesshoumaru has lived many years, I don’t think he’s going to live forever. I’ve wondered before if they can live forever as long as they weren’t killed or injured, but I somehow doubt that as well. One point to consider, however, is the fact that he has the Tenseiga in his possession. As we know, the Tenseiga is able to save him from mortal injury and it’s also able to bring back the dead. Given this reasoning, it is possible that with the Tenseiga, he can perhaps be immortal.
