I understand this question seems silly but why does every old person in Naruto have grey or white hair besides Danzo? Mito and Ashina are from the Uzumaki clan, known for vitality yet their red hair turned white, Madara had Hashirama cells like Danzo yet it also turned white.
I’m sorry but she is a Kage level shinobi 😭her death is almost as bad as Nawaki. Can you imagine someone like Minato or Jiraiya dying to a hail of kunai? I know she was stabbed in the back but like how was she not able to react. I would expect high level shinobi to be able to feel even the slightest of moments or detect killing intent, like when Kakashi was able to substitute before the demon brothers killed him with their ambush, I know he realized the puddle was a trap but even without that I don’t think they could’ve caught him off guard.
