Crimson Ties- Muzan Kibutsuji's Daughter

Hisana Kibutsuji is the biological daughter of Muzan Kibutsuji and is half human, half demon. Prior to the events of demon slayer, Muzan marries a woman named Amaya Ubuyashiki, who is Kagaya's adoptive sister. She ends up leaving Kagaya's family to marry Muzan because she was too afraid to tell him she had fallen in love with the demon lord himself. After she is born Amaya discovers that Hisana is immune to the sunlight, something Muzan always wanted. She is afraid of what he will do to their daughter if he finds out, so she ends up putting her in the care of some close family friends who raise Hisana as their own, so Muzan can't find her.

Hisana meets Tanjiro and Nezuko and ends up going on adventures with the two of them, Zenitsu, and Inosuke. Will she end up becoming a demon slayer, or will she join her father to put an end to the slayers as well as her friends? This ties into the plot of Demon Slayer, I'll simply be changing some details to add Hisana into the story. I will add some of my own twists to the plot as well.
