Diam was a humanoid demon with fish like qualities. He had a set of three ridge-shaped fins on his head and gills on his stomach, his skin was covered in black markings.


Diam took part in the kidnap of Jeanne D'Arc  where she was tried at Magistrum's court. He is presumably killed when Akira arrives.
