Sebastian Michaelis
The perfect butler who executes orders with demonic precision, waiting only for the moment he may feast on his master's soul.
Sebastian Michaelis serves as the devoted butler to Ciel Phantomhive, a twelve-year-old Earl operating as the Queen's Watchdog in Victorian-era London. Originally a dog named Sebastian, his namesake was adopted by the demon after he saved Ciel from a cult of sadistic worshippers. In exchange for helping Ciel exact revenge on those who tortured him and murdered his parents, the demon secured a Faustian contract to consume the boy's soul upon completion of that goal. This agreement binds the entity to protect and serve Ciel while hiding his true demonic nature behind impeccable manners.

Lore & Background
Sebastian is a demon summoned during a sacrificial ceremony where Ciel was held by unidentified perpetrators. Unlike the cult that performed the ritual, Sebastian arrived in response specifically to Ciel's summoning. He killed every cultist member and placed the contract symbol on Ciel's right eye. As part of their pact, Sebastian must fulfill any command given by his master until Ciel achieves revenge for the destruction of the House of Phantomhive. Once that goal is met, Sebastian will consume Ciel's soul as payment. To assist in this mission, Sebastian recruited Mey-Rin, Baldroy, and Finnian to join the Phantomhive estate disguised as servants. He also helped Ciel navigate complex incidents involving the Aurora Society, a secret organization led by Undertaker attempting to reanimate corpses.
In Their Own Story
On December 14, 1885, following an attack on the Phantomhive manor where his parents and family dog died, ten-year-old Ciel was sold into slavery. He endured physical, mental, and sexual abuse at the hands of a demon-worshiping cult before summoning Sebastian during a sacrificial ceremony. The demon stated he came for Ciel, not the cult, immediately slaughtering the perpetrators. Afterward, Ciel named the demon after his deceased dog and they returned to society. Sebastian assumed the role of butler while Ciel took over his father's position as Queen Victoria's Watchdog. Later, it was revealed that Undertaker had revived the original twin brother who was sacrificed during the ritual, forcing the current Ciel and Sebastian to flee as fugitives to prove innocence and stop the Aurora Society.
Reader's Guide
The contract between Sebastian and Ciel is a Faustian agreement where supernatural service trades for a human soul. Demons in this context cannot be harmed by conventional means and possess immense physical capabilities, though their power relies on the specific terms of the blood-signed pact. The symbol on Ciel's right eye marks this binding; it ensures Sebastian remains loyal until revenge is achieved. If the objective is completed, the demon consumes the soul to seal the deal permanently. This dynamic allows Ciel to utilize a dark entity for justice within the underworld of London while maintaining his cover as a nobleman. The system requires strict adherence: Sebastian must execute every command without fail until the contract concludes.
