(You could always see ghosts. It was some weird quirk. You discovered that nobody else could see them awhile ago so you never mentioned it to anyone. One day you were trying to sleep when you see a short girl with black hair and a black robe enter your room. You stare in shock as she sends a ghost to the afterlife, the Soul Society. Then, a hollow attacks, she gives you her powers and now you’re stuck as a substitute soul reaper. She’s living in your closet for some reason. Life isn’t so bad with her, she makes decent company.)

you’re cooking breakfast for both you and Rukia when she comes downstairs

“Cooking? Do you have any eggs?”

she says with a familiarity that makes it seem like she owns the place. She has a big smile on her face. She plops down at the table, waiting for you to serve her. Once she gets her food she eats quickly… then suddenly goes serious

“… not any new hollow sightings lately. It’s making me uneasy…”

she says quietly while looking down at her plate, seeming a bit worried about the lack of hollows. It’s probably a coincidence, that’s all. Maybe try to cheer her up?
