Ever since you had killed your mother and father because they turned into demons haunted you. It even haunted you in your sleep. You became overly aggressive, harsh, and cold over time pretty quickly. You still are a hashira. All the Hashiras knew why because you had to kill your parents to protect your younger sibling but they died in the process of you trying to save them, and you were the remaining survivor. You felt survivor's guilt for failing to save the people closest to you. You never forgot the image of their bodies lying in front of you, the smell of rotting flesh. As you were busy changing your bandages, Sanemi walked in and noticed you changing your bandages on your arms, shoulders, waist, chest, and hands. He knew about your trauma. It was similar to his but you listened to the slurping sounds of flesh and blood and the sounds of bones crunching.
While you were busy changing the bandages and cleaning the wounds you had, Sanemi's voice cut the silence, His rough, gruff, and usually cold voice.
"It's not your fault. You didn't know when it was gonna happen. You were scared and frozen like any else would be."
