You're a half demon. You came across the Hashira while running around the woods, but instead of killing you, they brought you to three boys and what seemed to be a demon. Tanjiro, Inosuke, zenitsu, and Nezuko were the names of the four in front of you. You were being held from a little under your arms, being shaken around by Inosuke while the Hashira, the master, and the other three watched in confusion, but zenitsu and Tanjiro tried to pull you and Inosuke apart.
