The manga follows Ciel Phantomhive, Sebastian Michaelis, and the Phantomhive servants as they investigate a series of mysterious deaths in Germany. Queen Victoria informs Ciel about these deaths, which are described as "grotesquely deformed" and then fatal. Unable to refuse, Ciel embarks on the mission, discovering the victims died from "the witch's curse" in a village.


Ciel Phantomhive and Sebastian work together to solve a puzzle and uncover shocking truths in the Emerald Witch Arc arc. The anime adaptation is not yet green-lit, but the cryptic ending of Black Butler season 4 has sparked fans' curiosity about the title, as the official staff has not green-lit the sequel.

What Is the Relationship between Ciel and Sebastian?

The Black Butler series revolves around the master-servant dynamic between Ciel, the young Earl of Phantomhive, and Sebastian, a demon obligated to serve him. The anime, particularly the latest Black Butler: Public School Arc, showcases deeper emotions and motivations, making it a BL-friendly series.

Their relationship is always portrayed as master and servant, yet there are a few instances in both the anime and manga series that imply a more complex relationship between them.

The series explores the complex power dynamics between Ciel and Sebastian, blending loyalty, duty, dependency, authority, obedience, and manipulation to create a multi-layered and intricate relationship.


The master-servant relationship between Ciel and Sebastian, established through a contract, allows Ciel to direct Sebastian's actions and decisions without difficulty. This relationship is crucial to the plot, generating much of the action and drama throughout the series, as it establishes Ciel's control.

Sebastian, on the other hand, is required to obey Ciel's commands with unflinching loyalty and obedience, both of which are critical components of their partnership. His skills and abilities are an invaluable asset to Ciel, further solidifying their relationship and cementing their bond.

Sebastian's influence on Ciel in Black Butler is evident through his manipulation and guidance. Ciel frequently seeks Sebastian's perspective on challenges and conflicts, providing him with advice and assistance. This subtly influences his master's decisions and actions, fostering a trust and understanding between them that transcends mere servitude.

Their master-servant relationship is characterized by sync. Sebastian displays a deeper understanding of Ciel’s desires and purpose, while the latter has huge trust in the former’s abilities.
