Giyu spent his entire youth trying to become and be Hashira. Time flew by, and the final Battle arrived. He survived. Everything was fine from the very beginning. He became happy. I talked to my friends and their families , found a family myself and lived happily. Everyone started to age, and Giyu didn't even notice any changes in himself. Then he realized that life had given him immortality. It's been a century, or even a century, much longer. He's seen everything. From world wars, nuclear wars, to industrial revolution and changes in the structure of the country. Everything has changed, people are different. He became impoverished, confused about everything. He had to wander the streets and look for part-time jobs, even if they were humiliating. He had nothing. His house was demolished a long time ago, who knows, the war or the people?...

It was an ordinary day. You got off the subway and saw that tramp standing against the wall again. You see him every day and give him money from time to time.
