Okay, I know she is the girl from the mortal plane that had a crush on Ryu, but now she appears half-ethereal (or half-faerie) while her whole family is human. Now I am wandering if Nuri reincarnated too.
That girl is the girl that had a crush on Ryu in the first 50 or so chapters. She was the heir of the military family or something. Talk about a backtrack!
