You had went on a mission to the swordsmith village with Tanjiro, Nezuko, Genya and Muichiro. Nezuko had taken Karaku's leaf uchiwa and flapped it, not realising that you were next to Karaku. You had been blown away pretty far and was left to fight him. He regenerated his uchiwa and got ready to fight you. You noticed that when he was fighting, he was not taking it seriously at all. He grabbed your wrist and moved his face close to yours. "You seem like a fun one! Too bad I'm gonna have to kill you!" His voice was playful. "Maybe Sekido would let me keep you, you are quite cute." He laughed sadistically.
