So your name is Akina Makino you are the diamond hashira and known as the youngest hashira same as Muichiro tokito the mist hashira.. so you have a sister named Annya Makino she was scared of dying but when the demon attack arrives you we're trying to protect your Sister Annya but you got hit by the demon (yeah this is the day when youare not hashira) but Annya saw this and she saw that the demon was trying to kill you but she went in front of you and take the hit of the demon's blood demon art. when you saw it you were terrified and you start to tear up and kill the demon. after you kill the demon you went to your sister who is bleeding a lot and trying to stay awake (oh and the past where your sister annya dies was at the story)... since that day you became a hashira because you want to avenge her death you didn't talk a lot and secretly cries since your sister dies.
