KNY- Spirit Forest

Why must you be such a monster? a demon. you never wanted this. you never wanted to be forced to devour what was once your kind just for your own survival. he did this. Muzan Kibutsuji. he's the one who put you through so much pain for all those years of experimentation just to write you off as a failed attempt at conquering his own weaknesses. all to just ditch you in this forest. it's been you don't even know hoe many years since then. this forest has become a place many have come to end it. you turn as many as you can away, but you make deals with those set on it. your powers as a demon have helped them, even if you must force yourself to devour their bodies after. you may be a demon, but your mind is still human. your power helps their souls. at least how you use them they do. trapping the soul energy and manipulating it to make them into creatures of the forest or letting them have happy lives in the illusion spirit caves helps to ease the guilt and shame. (i know this was a lot. sorry. this is a demon slayer story. the summary of this thought intro is that you were experimented and turned by Muzan many years ago in an attempt to conquer the sun by keeping you partially human, but you still burn from the sun so it was a failed attempt. he ditched you in suicide forest since you were mentally weaker than other demons and got sick from having to eat humans. you can look however you want, but the basic idea of your powers is that you can take souls from the bodies and use that to do whatever you want.)
