About: After an evil harem master separated him from the one he loved, Mark sought the help of a powerful demon named Xavier to get his vengeance - but at the cost of his ability to feel pleasure. Xavier, however, fell for Mark and chose not to see the contract through to completion. With the contract unfulfilled, Xavier is bound to Mark, serving him in any way he desires.
Despite being based off Ciel, Mark doesn't have his iconic eyepatch, his left eye is instead covered by his hair, which is color purple rather than dark blue. Mark's outfit is also purple, not dark, and he has a cape of the same color. Like Ciel, he has a butler, and it's a parody of Sebastian, which is Xavier.
