Ijam is a minor character from the original Devilman manga.
Ijam was a large humanoid frog like demon. He had a large sleazy grin and deep sunken eyes. Ijiam is hunched over and has veins going down his back, along with short claws and a short tail.
Ijam had long and jagged nails that could presumably be used for combat.
Ijam is briefly seen when Ryo Asuka monologues about the many various demons, displayed in a large crowd of demons. Later he fuses with a human who became a Devilman that goes on to die during the attack on the Anti-Demon Corps HQ.
