~CRYSTALFLIES~ (An original demon slayer fanfiction story)

Silviannah Kibutsuji is a 13 (In human years) year old demon girl who is pretty much the most powerful demon to ever exist. Only one catch though... she's a half demon. Her mother, Kristen Hallows, was the master witch, who was married to Muzan Kibutsuji, the demon king and Silviannah's father. When Silviannah was 4 in human years, she had met Yoriichi Tsuguni, and taken a liking to the man. She had brought him home, and he had ultimately killed her mother, and 18 siblings. After this, Silviannah became unpredictable. Join her in her journey to change the original timeline of "Demon Slayer", and protect all she cares about!

(Cover art is mine, and yes, I used a base to make it, so credit to the person who made the base position, but please don't steal my art! Demon slayer is [obviously] not my story, so credits to the creators, but Silviannah IS MY CHARACTER! Please don't create a story using her, I worked very hard on making her and her backstory, so if you want to use her, please ask! Thanks!)
