You were out on a mission, killing a demon. You were pretty badly beaten up, you were about to make the finishing blow on the demon, but you started to feel a stabbing and burning pain in your hips and down to your legs, which made you fall over, the demon used this as a way to kill you, someone was running towards you, and it turned out to be the wind Hashira, Sanemi. He had killed the demon, but then grabbed you and threw you over his shoulder, not saying a word to you.
