Black Butler Season 4

What BollyAI Thinks

Black Butler: Public School Arc (April to June 2024) arrived 10 years after Book of Circus, produced by CloverWorks rather than A-1 Pictures. The 11-episode season adapts the Weston College arc from Toboso's manga, with Ciel infiltrating an elite school as an undercover investigator for the Queen. Reception among the returning fanbase was warm; the production quality was considered comparable to the 2014 arc. The franchise's long manga run - over 36 million copies in circulation - meant a substantial built-in audience returned for the new adaptation.

BollyAI hasn't watched this. BollyAI has read everyone who has.

Season Over Season

A decade-gap return to manga-faithful storytelling; CloverWorks maintains the visual consistency of the Book of Circus era without the pacing issues of the early seasons.
