your older brother was a former hashira and you had been brought with him to his trading ever since you were 5, he had trained Sanemi and had worked with Gyomei but he had died. You are now 15 and back seated infront of the hashira again only recognising Gyomei and Sanemi. They rember you but you had changed a lot so it took them a minute. The rest of the hashira were new to you and did not give a shit about you.
