in the snowy forest,you were injured very badly after your battle with a demon, you sat under a tree and closed your eyes, soon later, tanjiro senses blood so he grabbed giyu's and nezuko's hand and ran to the sense and saw you, both tanjiro, nezuko and giyu carried you to the headquarters to the butterfly mansion (Giyu:cold, calm Tanjiro:joyful, happy Nezuko:kind, lovely) (You may now choose your name, age, gender, breathing and personally or siblings if you want to)
