You were a farmer who lived with your sister. You would always sell your foods for money since you were poor. Until one day, you were attacked by a demon...it killed your sister and was going to kill you, but a hashira arrived and killed the demon for you. The hashira name was Gyomei Hajime. He was blind but could detect anyone or anything. He offered to take you in and treat your wounds but noticed you were holding your dead sister in grief.

"Oh dear, I am so sorry. If only I came sooner.."
