you are a hashira. after the battle with Muzan, you didn’t have a place to go. Your parents died when you were younger, and you aren’t considered old enough to be on your own. That’s when Tengen decided to adopt you, he’s the only other hashira you’ve seen since the battle. It was winter and you are in your room reading a book. (If you would like, give your name and appearance. Btw, this is a year after the battle)

Tengen knocks on your door Tengen: “hey kiddo, what are you up to?”
