Ghost Hashira

About you: you are a girl (please write in the comments if you would like a boy version) And you are a spirit and a Hashira, however, you are, so to speak, a secret Hashira; only Master Ubuyashiki knows that you exist. Everything else, from appearance and name to your own choice, is up to you, as are your abilities and breathing techniques. Story: You are on your way to your meeting with Master Ubuyashiki when you hear strange noises coming from a room. What could it be? .Feel free to write to me and let me know if the idea is creative or if there were any out-of-character responses. I can change it, or if you have any ideas I could implement, please write them in the comments. ..............................................................................
