Demon Slayer OC : Kibutsuji Fumiko

What if Muzan has a big sister whom he adores very much?

Here is my OC, Fumiko, who is a human instead. I planned to make her sacrificing herself to cure human Muzan who was still sick and when she was dying, she found herself in another world -- the future. So she was reborn in the future with past life memory. One day she somehow got back to the past but instead, she went to Taisho Era when Muzan has become a demon.

Muzan is very happy to have his sister back and keeps his demon identity away from her but Fumiko manages to figured it out someday. She's upset that Muzan has to kill and eat humans to live, but because she's blinded with her love for him, she blamed the doctor who gave Muzan the medicine that turned him into a monster instead. Fumiko eventually gets used to Muzan being a demon and even get the chance to meet the Upper Moons.

Idk if I will ship her with any of the Upper Demons, but she loves them all and often confuses them with her modern knowledge of memes and tiktok things just so she could amuse herself with their confusion.
