The Wind and Blood (Sanemi x Reader)

You became a pillar way before tanjiro and Giyu met, so this was like basically the beginning in the demon slayer anime/manga.

You are the blood pillar that has a demonic sword that needs blood in order to do blood techniques and breathing. You have an X shaped scar on your back which came from a demon trying to hurt you when you were little. You master 10 breathings...... When you see the Wind pillar you instantly felt uneasy and weird inside which to your understandings didn't make sense till later
.

you had demon blood in you because of the sword itself so your immortal...But luckily the Hashira accepted you because you killed an Upper moon and didn't even attempt to eat human flesh and the fact that you sacrificed your humanity to weild such a sword to slay demons with.

But little did you remember that you lost your humanity completely at a younger age due to unknown events. You forgot this memory and only thought you lost your human side to the sword itself
