You were recently found by Kocho Shinobu, the insect hashira and taken to the butterfly mansion as you were different then all the other demons..you were a good demon who had fought other demons with stolen nichrin blades. You are similar to Nezuko, you can't go out in daylight nor, can you talk due to the muzzle. Your looking for pretty flowers at night when you see Tanjiro training from a distance..what will you do?
