Sebastian's Original Name

Lore & Background

The narrative establishes that Sebastian Michaelis is a high-ranking demon who entered into a Faustian contract with Ciel Phantomhive. The source clarifies that this agreement was formed during a sacrificial ceremony where a sadistic, demon-worshiping cult attempted to summon a demon but failed in their intent. Instead, the entity arrived in response to Ciel's own summons. As part of the terms, Sebastian agreed to serve Ciel and help him achieve revenge on those who tortured him and murdered his parents. In exchange for these services, Sebastian is permitted to consume Ciel's soul once the contract is fulfilled. The text notes that Sebastian named himself after Ciel's deceased dog, a fact that serves as his identifier within the story, but it does not reveal any name he held prior to this moment.

In Their Own Story

The events leading to Sebastian's current identity began on December 14, 1885, when the Phantomhive manor was attacked. Ciel, then ten years old, was taken captive by a cult and subjected to physical, mental, and sexual abuse. During a ritual intended to summon a demon for the cultists' purposes, the demon arrived but clarified he responded only to Ciel's summons. Ciel sold his soul to secure his rescue; the demon subsequently killed all cult members and placed the contract symbol on Ciel's right eye. Upon their return to society, Ciel named the demon 'Sebastian Michaelis,' explicitly stating this was done after his deceased dog. This moment solidified the name that would be used throughout their service as Ciel assumed the role of Queen Victoria's Watchdog.

Reader's Guide

Fans seeking information on Sebastian's true identity must rely strictly on the established facts: he is a demon who formed a contract to consume Ciel's soul in exchange for revenge services. The source confirms his current name, 'Sebastian Michaelis,' was chosen by Ciel following the ritual that saved him from slavery. There is no mention of a previous name or any alternative designation used by the entity before this event. The narrative focuses on the dynamic between the demon and his master rather than exploring the demon's history prior to the contract.
