Ghelmer was a water demon from Devilman Grimoire. He possessed the adult human woman Senda Mari and served Sirene.


Ghelmer was a large, lean demon with long spindly limbs and a skeletal figure. He stood hunched over with a long neck and has a long neck, an overbearing jaw, pupilless eyes and large ears that resembled bat wings. He had long, sharp fingers on each hand and had a slug for a lower body.

Upon leaving Miki's body, he becomes very small. Later on, when he fuses with Ebain, his face appears on the front of her lower body, which is all liquefied.

Powers and abilitiesEdit

Ghelmer could manipulate water to his liking as well as fuse with it, meaning any physical attacks would not work on him.


Ghelmer, when using his human disguise of Senda Mari, likes to use her attractive features to let his opponent's guard down. He is also very vicious in battle, refusing to hold back and is even willing to fuse with an unwilling partner.
