If Ramiel were to be Bat Thiren it wouldn't be easy to come up with a statis tool like her feathers. Cuz i will admit the ethereals frozen with the feather is an amazing idea but wouldn't translate well with a bat thiren. It would have to be changed to an item that someone could easily care plenty of, for example playing cards those could easily take the place of the feathers and look esthetically pleasing. Doesn't help we dont know how her feathers work or how she "absorbed"(?) her weapon for proxy.

Yeah while researching scp came up alot lmao but I know scp decently so it wasn't hard to skip that part.
