OVA, an abbreviation of Original Video Animation, is a special episode of an anime that is not aired on television, but is instead released directly in home-video formats (such as DVD or Blu-ray). An OVA often has little or no relation to the plot of the series.

All Kuroshitsuji OVAs besides Kuroshitsuji: Book of Murder, which adapts the Phantomhive Manor Murders Arc, are non-canonical.
