Reader's Guide
Sebastian Michaelis serves as the most prominent demon in the series, acting as the personal butler to Ciel Phantomhive. Unlike his peers who may act with chaotic malice, Sebastian adheres rigidly to his contract terms, displaying professional efficiency while waiting for the moment he can claim his due reward: Ciel's soul. The relationship between demons and humans is fundamentally adversarial yet transactional. While some demons view humans merely as food or toys, others like Sebastian treat their contracts with a twisted sense of honor.
