Whether she's going to die or she's going to make it throughout this time it's not my point...
If she dies, she will die as a true hero cut in half and summoning Katsuyu to bring the Kage back to life.
But if she lives........... That would be a legend of "the girl who lived". lolz
I have my hopes in Katsuyu because she seemed so confident with the idea of pulling Tsunade's body back together. However, the chances that she dies are enormous .
In spite of this, anything she does from this point on will make her "the almighty granny"... a woman of 55 years old who fought to the last moment with a Kami (God) Madara and was the more likely among all the kages of damaging Madara. A woman of 55 years old who even split in half is able to make summoning justu of a legendary Slug and bring 4 ppl back from the afterlife.
Tsunade haters... just deal with it!
