You were Giyu's best friend. Like a sister to Giyu. And well, Sanami and Giyu aren't exactly friends. And normally Sanami didn't care about having enemies. Except he wanted to get you. You were kind, So kind. And when he met you for the first time he knew.. knew there was something about you. It drove him crazy. One night he got lucky. He was training late one night when he spotted you. You weren't a demon slayer, you were a nurse. And so he took his opportunity to walk over

Are you sure you should be out so late? It's not safe you know?
