Black Butler

• 1. Introduction

  ›

  Black Butler, the manga series written and illustrated by Yana Toboso, opens on a single night in Victorian-era London that changes everything. A twelve-year-old boy named Ciel Phantomhive stands at the center of a summoning ritual performed by a demon-worshiping cult - and when the demon arrives, it does not answer the cult's call. It answers Ciel's. That exchange - a child's soul for revenge - is the contract at the heart of one of the longest-running manga series in Japan. What drives a boy to bargain his very soul? How does a story rooted in grief, servitude, and the supernatural become something read by tens of millions of people worldwide? And how does a single manga chapter from September 2006 grow into musicals, films, video games, and animated seasons still airing nearly two decades later? Those questions are what this documentary sets out to answer. The series has been running in Square Enix's Monthly GFantasy magazine since the 16th of September 2006, and by August 2025 it had over 36 million copies in circulation worldwide. One place to begin is with the boy at the center of it all, and the night that made him.

• 2. The Contract and Its Cost

  ›

  Ciel Phantomhive acquired his title as Earl on the 14th of December 1885 - the night of his tenth birthday - when the Phantomhive manor was attacked by unknown assailants. His parents died that night, along with the family dog, whose name was Sebastian. Ciel was taken, sold into slavery, and passed into the hands of a sadistic cult that subjected him to physical, mental, and sexual abuse. It was during one of their sacrificial ceremonies that the demon appeared. The demon told the assembled cultists that he had not come in response to their ritual. He came because Ciel had called him. Ciel offered his soul in exchange for salvation and revenge. The demon killed every cult member present and marked Ciel with the Faustian contract symbol on his right eye. Ciel named the demon Sebastian Michaelis, after his deceased dog - a detail that quietly says something about how grief shapes the choices we make when we have nothing left. Sebastian assumes the role of the Phantomhive household butler and, by extension, Ciel's primary weapon. To fill out the estate's staff, Sebastian recruits figures who each conceal considerable capabilities: the sniper Mey-Rin, the veteran soldier Baldroy, and Finnian, a teenager with superhuman strength, all serving as servants in disguise. Together they return Ciel to his family's place in society, and to his role as the Queen's Watchdog - the person Queen Victoria tasks with investigating threats too dangerous or too sensitive for ordinary channels.

• 3. The Queen's Watchdog

  ›

  Serving as the Queen's Watchdog means operating at the boundary between official London and its criminal underworld. Ciel and Sebastian take on cases that Queen Victoria herself deems threatening to England, which places them in contact with dangerous organizations, criminal networks, and supernatural forces that official institutions cannot or will not handle. One recurring thread involves the Aurora Society, a secret organization conducting experiments with reanimated corpses. The organization is connected to a grim reaper known as the Undertaker, who has his own personal ties to the Phantomhive family. What seems like a straightforward mission of revenge gradually reveals a more complicated truth. The Undertaker's true objective is the reanimation of Ciel's older twin brother - the original heir to the Phantomhive estate, who had been sacrificed during the cult ritual that summoned Sebastian. The revived twin incriminates his younger brother for crimes connected to the Aurora Society and seizes control of the Phantomhive estate, forcing Ciel, Sebastian, and their allies to flee as fugitives. Toboso structured this revelation to reframe everything the reader has already witnessed. The boy who assumed the Phantomhive name and the Earl's identity was never the rightful heir. His entire arc of revenge and duty has been built on a displaced identity. Ciel and his allies then turn to investigating the Aurora Society not only to stop Undertaker's plans, but to prove Ciel's innocence. The series went on hiatus in June 2024, with Toboso conducting research as the story heads toward its climax, set to resume on the 18th of April 2025.

  In July 2008, it was announced that A-1 Pictures would produce an anime adaptation of Black Butler, directed by Toshiya Shinohara. The series premiered in October 2008 on MBS and TBS, running for 24 episodes through March 2009. At an event on the 14th of June 2009, it was announced the series would return for a second season. Japanese voice actor Junichi Suwabe confirmed the news on his official blog the same day. The second season introduced two new main characters - Claude Faustus and his master Alois Trancy - alongside the returning Sebastian and Ciel. Both new characters were designed by Toboso herself. That second season ran for 12 episodes, from July to September 2010, and followed an original storyline not drawn from the manga. A third season, titled Black Butler: Book of Circus, arrived in July 2014, and this time marked a deliberate return to the source material, adapting the Noah's Ark Circus arc. Its director was Noriyuki Abe at A-1 Pictures. Paired with it was a two-part theatrical OVA, Black Butler: Book of Murder, which screened in Japanese theaters on the 25th of October and the 15th of November 2014, adapting the Phantomhive Manor Murders arc. A fourth season titled Black Butler: Public School Arc, produced by CloverWorks and directed by Kenjirou Okada, broadcast eleven episodes from the 13th of April to the 22nd of June 2024. A fifth season, again directed by Okada and produced by CloverWorks, aired from the 5th of April to the 28th of June 2025. The licensing history in North America is its own story. Funimation first announced their license at their FuniCon 3.0 online panel on the 29th of March 2010. The series made its North American television debut on the 8th of February 2011, on the Funimation Channel. Funimation lost the rights to the first season in 2017 and to the second in 2018; those rights were later acquired by Aniplex of America. A Blu-ray Disc box set of the first season was released by Aniplex on the 29th of January 2019. Funimation eventually re-licensed both seasons for its streaming service in November 2019.

That production was written by Mari Okada, directed by Sakurako Fukuyama, with music composed by Taku Iwasaki and lyrics by Yukinojo Mori. The musicals continued to evolve. A fourth production, based on the Noah's Ark Circus arc, ran from November to December 2016, and by that point Izumi Shuuhei - who played the Undertaker - was the only original cast member still performing across productions.

  The comics anthology Rainbow Butler ranked seventeenth in Oricon's weekly chart during the week of the 31st of March to the 6th of April 2009, selling 41,083 copies after ranking thirty-third the previous week. The fourth and fifth manga volumes ranked thirty-third and thirty-ninth of the top-selling manga in Japan during 2008, selling 529,210 and 468,550 copies respectively. The sixth volume ranked thirteenth of the top-selling manga in Japan during the first half of 2009, selling 619,501 copies. The series itself ranked tenth of the top-selling manga in Japan during 2009, with an estimated 1,603,197 copies sold that year alone. By August 2025, the total worldwide count had reached over 36 million copies in circulation. Individual volumes have appeared repeatedly in Oricon's weekly best-seller chart, occupying multiple positions simultaneously. The cultural footprint extends into how readers relate to the characters directly. The Japanese music distributor Recochoku runs an annual survey asking which anime characters people would most like to marry. Sebastian Michaelis ranked ninth in the category for the character people want as a groom - a detail that speaks to how the demon butler, despite his supernatural nature, struck readers as genuinely compelling. In North America, Yen Press licensed the series for English and serialized it starting with the August 2009 issue of Yen Plus, chosen to mark the magazine's first anniversary. The English first volume was released on the 26th of January 2010. As of the 18th of June 2024-33 volumes had been released in English. The first Square Enix tankōbon volume was released on the 27th of February 2007, and as of the 27th of November 2025, thirty-five volumes had been released in Japan.
