Demon butler and a senior staff member of the Phantomhive household. Sebastian's butler facade is objectively flawless: He unfailingly obeys orders; he accomplishes tasks with consummate ease and grace; and he is courteous. Nevertheless, Sebastian is in actuality a callous and sadistic demon; he is ruthless when attacking others on Ciel's orders, and he occasionally puts Ciel in nonfatal danger for the sake of his own amusement.
