The Angel's face separates into two parts, becoming a mouth. Inside the mouth is a shining sphere.

UrsusArctos: The script description is odd, it reads to me like Gaghiel didn't have a mouth until it decided to give itself one on the fly to bite the Eva with. The teeth inside look to be arrayed in rows like a shark's teeth but appear to be conical in shape rather than serrated and triangular like in most carnivorous sharks.
