Am I talking about Karin or Naruto here? (To Salmander particularly, we've seen what a Hamura decedent and a Ashura incarnate can do via genes... it is called the JOUGAN)
Even if she got one of any of those abilities/traits it is better then literally 0 is it not?
Idk why some people can't get it.
We would have this Sarada but with more stuff, which means she is potentially better.
It costs stamina
I was fusing both life force, durability and chakra into one scenario
Tsuande saved Shikamaru with that said chakra, had herself look youthful again when during the Pain arc it took her days to even wake up
and on top of that Karin wasn't tired from it
