Y/N knows how this story ends.

She knows who dies, who suffers, and which smiles won't last.

When she's suddenly thrown into the world of Jujutsu Kaisen shortly before canon begins, she decides she'll do the impossible:

Save everyone.

Armed with canon knowledge, a dangerous amount of determination, and a cursed technique that shouldn't exist, Y/N begins changing the future one mistake at a time.

Unfortunately, fate pushes back.

And the more she changes the story, the more the story changes her.
