Six episodes of pure chaos dressed up as bonus content. The "Making of Black Butler II" operates like a Hollywood behind-the-scenes mockumentary, which means you get to watch the cast roast each other while pretending to film an anime that doesn't exist. Everything else is exactly what it promises: Ciel in Wonderland territory, a ball simulation that lets you pretend you're part of the mansion, character spotlights that wouldn't survive in the main series but thrive here. You're watching people who know the show well enough to break it without permission. The weakness is real, some OVAs feel stretched thin and the Wonderland episodes wear thin on repeat. This exists for fans who've already committed to the franchise and want to hear these characters riff on themselves.
Six standalone episodes serve up a chaotic carnival of content divorced from the main narrative. One arc reimagines the Phantomhive household as twisted versions of Carroll's Wonderland characters, complete with Sebastian as the Cheshire Cat and Ciel as an appropriately distressed Alice. Another episode lets you step into an interactive ball at the mansion, where Elizabeth plays hostess to mysterious guests. A Hollywood-style documentary pulls back the curtain on production itself, featuring in-character interviews with demons, young masters, and death gods discussing their work like film industry veterans. The final arc follows William and Grell as they wrangle newly recruited shinigami, revealing how the Reaper bureaucracy actually functions beneath all the chaos. These OVAs operate as pure fan service: parody, world-building, and fourth-wall breaking bundled together. They work best if you're already invested in the characters and want to see them unmoored from serious plotlines. Expect absurdist humor, weird genre experiments, and the kind of self-aware ridiculousness that comes when creators give themselves permission to play.
