Grimoire had a tall, imposing figure. He had pale skin, jet-black hair and crimson eyes, he wore dark gray clothing segmented in joint sections by black leather straps with silver clips and light brown boots. He wore a black leather overcoat and on his right thigh bore an accessory (presumably a gun holster) secured by light brown straps. Grimoire's red ascot is reminiscent of his son's red bandanna.
