Between the flashbacks, and what we are shown with Yu in the present, it is one tough guessing game! The giant black wing one seems to be an out of control, kind of intermediate stage. Perhaps the complete seraph is the multiple winged one, maybe Yu now has the genes for The King Of Salt seraph, or something else!
