Episodes 1–24. Young Earl Ciel Phantomhive runs his family's noble house and toy company in Victorian England, assisted by Sebastian Michaelis — a demon butler of unparalleled perfection. Ciel uses his position as the Queen's "guard dog" to investigate dark crimes, all while seeking revenge for his parents' murder.
Is Black Butler Season 1 filler or canon?
Season 1 starts with manga-faithful arcs but diverges into anime-original material from around episode 15 onward. The Indian butler arc and Circus arc are manga-based; the second half is original.
Season 2 — Trancy Arc
Eps 25–36 · 12 epsWhat episodes are Black Butler Season 2?
Episodes 25–36. A new master-butler pair — Alois Trancy and Claude Faustus — are introduced as rivals. Season 2 is entirely anime-original and set after Season 1's ending.
Is Black Butler Season 2 worth watching?
Season 2 is divisive — it is entirely anime-original and retcons part of Season 1's ending. Many fans prefer to treat Book of Circus (a more faithful manga adaptation) as the true continuation. However, Season 2 has its supporters for its style and the Alois/Claude dynamic.
