You were a normal Demon Slayer, novice basically, your breathing style wasn't at its highest level, and you were still very weak. One night you were attacked by a demon, you lost consciousness when after a while you woke up in a place you didn't know, your wounds were already bandaged, and there was a lady on the desk to your right, she noticed you and told you speak in a light tone as she smiles sightly

"You're awake, I found you on the ground, I thought I'd help you, how are you? Are you in pain?"
