Death?

You lived as a real Gen Z and now it was time for you to die as a real Gen Z, But what happends when you don't die but wake up inside a famous Japanese anime called Kimetsu no yaiba
But what you find interesting is that you're not a human nor a demon, just what are you?

Charcters don't belong to me, credits to Kimetsu no yaiba

also characters might (most likely) not act according to anime / manga
