How to Survive in the Jujutsu World After Cosplaying as Muzan

I’m an ordinary college student. My roommate got me to cosplay a character from an anime that’s supposedly all about being the ultimate survival expert, and, as expected, I transmigrated. But I’ve never watched that anime they call Demon Slayer. I have watched other stuff, though! Look at those ugly things flying all over the place, dropping my sanity just by being here. They’re obviously curses from Jujutsu Kaisen! This is the world of Jujutsu Kaisen! Oh, God! You sent me to the wrong world! Muzan, who only knows that he isn’t human, skulks around on guard, constantly alert so he won’t run into that human X-ray machine. He never imagined that guy would be nearby. Then he hears the devil’s whisper. “Geto! Look what I found!” “Gojo, don’t scare people.” “But it’s not human, so it’s fine to scare it! Look, these fangs! How fascinating!” I’m Muzan. Question: I just transmigrated into the Jujutsu Kaisen world. How do I explain to teenage Gojo and teenage Geto that I’m human? The main story is in third person. The pairing hasn’t been decided yet, but it’ll be settled before I start writing. It’ll be a standard 1v1. Theme: Respect life and cherish it.
