Jiang Nianyue has already died once.
She saved a child and was struck by a truck. As her consciousness faded, she had only one thought: I don't want to die. I want to go back.
The Corridor of Delusions answered her.
It's an infinite space that gathers the lingering obsessions of those who died unjustly. Instances are ranked from E to SSS, with multiple reincarnators matched for each round. Ghosts kill people, humans turn on one another, and sticking together isn't always safe. Going alone can make you harder to spot.
So when the six people in her round began introducing themselves and discussing teaming up, she turned and left.
It's not that she can't get along with others. It's just that her path has always been one she has to walk alone.
At the end of an SSS-rank instance lies the chance to go home. And she's going to clear it alive, all by herself.
