(Y/N) (L/N), ranked Kinoe in terms of strength and capability. Only 15 years old, and still among the ranks of the Demon Slayer Corps. She even created her own breathing style, and mastered it a year after it was formed! Song Breathing, as she always loved to sing, and can intertwine with Sound Breathing. However, the reason she's a demon slayer is not one many might expect. A boy... a boy she met 2 years ago... is now a Hashira. But he doesn't seem to remember her! Oh well, she remembers him. Very well. She'll wait as long as it takes... for Muichiro Tokito, the Mist Hashira, to remember their connection, all while her love for him remains strong.
