   Summary

   (Various! KNY characters x fem! Reader)

   You didn’t ask to be transmigrated.
   You didn’t ask to wake up as a demon.

   Thrown into the world of Kimetsu no Yaiba, you survive by devouring the very creatures you hate—while pretending to be a healer by day.

   Your only real goal?
   Help Tanjiro survive his destined journey… and find a way to become human again.

   But fate isn’t so easy to follow when your existence alone is already changing it.
