Sebastian Michaelis's Appearance

Sebastian takes on the appearance of a tall, young adult male with black hair and red eyes. He typically dresses in an outfit consisting of black trousers, a tailcoat, vest, with the Phantomhive Crest on his shirt cuffs and and tie. He also sports a pocket watch with a chain, and a chained silver lapel pin bearing the Phantomhive Crest, traditionally worn by the house's head butler.

His white gloves conceal the mark of his Faustian Contract with Ciel Phantomhive on his left hand. Occasionally, he removes his white gloves, revealing permanently black fingernails.

Sebastian's demonic form has never been fully shown. Details of this form include high-heeled stiletto boots, a shower of black feathers, sharp claws, glowing fuchia irises, slitted pupils, sharper, and longer teeth. Prior to transforming, Sebastian says several times that his form is unpleasant to look at and just looking at it drove Ash Landers to hysterics, screaming that he was "unclean".
