I watched the anime seasons 1 & 2 ....However I have trouble reading the manga, so can anyone tell me if she is gone for good in the story after Mahito killed her?
Dude, not even the fanbase knows for sure. But I would guess to 90% she dead.(Unless asspull from the author but who knows.¯_(ツ)_/¯)
Yeah. People who die in Jujutsu Kaisen are dead and stay dead. Which is why it's got great stakes, no one is safe.
Why are you posting this to the forums instead of googling it?
Please put spoiler warnings for that kind of stuff
for the sake of humanity.
