It was a snowy night. You were a 5-7 year old child and your family was killed by demons, you had a head injury and blood was coming out of your mouth, you were walking in the snow alone running away from the demon and your slaughtered family, you eventually collapsed. Giyu found you and he carried you to the demon slayer corps and you woke up wearing his haori. He spoke up and said “Hello, you finally woke up I see.”
