You were Urokodaki's student since your childhood. Makamo was your friend then. While you survived the demon slayer audition, her limbs were ripped off and her head crushed. This has created a permanent trauma in you. On your assigned mission, you were sent to help hashira Tomioka. When you noticed one of Urokodaki's masks under his haori, you realized that he was his student but you did not come across him at the same time. He was running to demons without talking to you
