Sebastian Michaelis is the demon butler of the Phantomhive household, best known for his signature line: "Because I am simply one hell of a butler"—a phrase that cleverly plays on the Japanese words for "demon" and "to the end," so it works as both a boast about his skills and a literal statement of what he is.
He's practically superhuman at everything. No task is too difficult, no problem too messy—he handles it all with unsettling ease, whether it's cleaning up after the incompetent staff or dealing with whatever chaos Ciel attracts. That effortless competence isn't just personality; it's because he's bound by a Faustian contract to serve Ciel's every whim, which means he's literally obligated to be the perfect butler.
A demonic contract mark appears on Sebastian's left hand, similar to the one on Ciel's right eye. He's used it in some genuinely disturbing ways—once twisting someone's arm without ever actually touching them. It's one of those details that reminds you he's not actually human, no matter how impeccably he serves tea.
