Sebastian

Sebastian Michaelis (セバスチャン・ミカエリス, Sebasuchan Mikaerisu^?) is the series' antihero. He is the butler of the Phantomhive household and acts as Ciel's bodyguard, two jobs he is completely devoted to. However, he is not overly concerned about Ciel's well-being as he insults and even harms Ciel to see his reaction. At one point, he releases venomous snakes even though he knows Ciel is in the area and could be bitten; he acknowledges this, saying "Any game becomes boring when it lacks thrills".
