The Emerald Witch Arc represents the ongoing adaptation of Yana Toboso's manga, which has been serialized since September 2006 and had over 36 million copies in circulation by August 2025. This season continues the narrative arc involving the Aurora Society and Undertaker, a grim reaper with ties to the Phantomhive family. The season's release in 2025 follows the manga's hiatus announcement in June 2024 and its planned resumption in April 2025. The anime series has seen multiple adaptations, with earlier seasons including original storylines not found in the manga, but later seasons like Book of Circus and this arc aim to closely follow the source material. The season contributes to the franchise's legacy as one of the best-selling manga series, with its blend of Victorian-era mystery, supernatural elements, and complex character relationships.
