Well it's...Kanade. That long injury I took to be more related to her power malfunction. She's like the big exception in the whole afterlife... we don't even know how exactly her powers fit into the grand scheme.
For the Iwasawa scenario, it'd make sense if it didn't affect her physically, but the flashback put her into a cycle of depression because it reminded her of her previous life.
