In which you're isekai'd from a parallel Jujutsu Kaisen universe (your own) to the canon universe. Jujutsu kaisen x reader, in later chapters character x reader but idk who yet

In which you find yourself in Demon Slayer after staying up too late one night and forgot to keep your sanity. "... Why am I here? Just to suffer?" "Y/n, I'm hungry." "... Crap." ... Demon Slayer, its story, and characters do not belong to me, they all belong to Koyoharu Gotogue. I only own this fanfic's plot.
