The Time Demons Existed Again..

P.O.V: What if 10 years after Demon Slayer, there was a new demon king and new hero's to save humanity? (TW: Mentions of death, suicide, minor swearing, mentions of blood and corpses, violence, basically all the Demon Slayer rating warnings)
Kinoko Kaneko is living in the Taisho Era Period in Asakusa, Japan. She was having an amazing life with her family until she came home and her family was killed right in front of her, while her little brother Kai, became a demon. Ever since then, she wanted to murder the man who was responsible for this. On the way, she'll meet new people, friends, or foes, and try to put an end to this nightmare. Permanently this time...
