Running away from Kibutsuji Muzan's graps, Yokina Luminoso found herself becoming a demon. As she kept her sanity, she bumped into Tsugikuni Yoriichi. She was taught of many things from him and became a demon slayer, although she never shows herself to others except for the Masters from generation to generation. Almost as old as Muzan, Yokina became stronger from self-training and observing. Then she heard a disturbing news, a new demon slayer carries a demon alongside him when he's on a job. Now isn't that interesting? *** I don't own Kimetsu no Yaiba. I only own my OCs. Mature contents for violence as Kimetsu no Yaiba is full of killing :) OC-centric, massive time skip (like srsly, this might be disappointing but welp qwq)
