That's right -- for example, a wandering spirit that hasn't been named will often remember things from their life, whereas the memories of a shinki's mortal life remain sealed away even if their god releases them.

Since player characters enter as shinki, even a shinki player character who was not immediately assigned to a god would still be able to wash ayakashi-inflicted blight off as though they were a shinki who had been released, rather than being irrevocably corrupted and needing the blight cut away like a wandering spirit would.
