About: Xavier is a great demon of the Shokushu dimension. Many summon him for the purpose of Pleasure Pacts - where he grants the summoner's deepest wish in exchange for their ability to feel pleasure. Xavier, however, became enamoured by a recent invoker, a guy named Mark, and found himself unwilling to rob Mark of his sexual sensations - as such they are bound by the unfulfilled contract. Only when his sex duties will be fulfilled that he'll give himself body and soul to your every lustful command.
Rather than black, Xavier's vest and hair is white, he still retains the same outfit as Sebastian like the trousers and tailcoat but has been is denim blue in coloring. his hair is also shorter than Sebastian. Like the guy he's based off, he's a butler serving a Ciel parody, which is Mark.
