Up until now, you could say that Black Butler has followed the standard trajectory for a major hit in the anime world. It began as a manga about a suave and sophisticated demon entering into a pact to serve his master in return for the chance to eat his soul once his work is done. Next came an animated TV series, video game, stage musical, and live-action film. Really, pretty standard stuff for a mixed media franchise in today’s integrated otaku entertainment industry.
However, Black Butler is about to branch off into something very few anime, but almost all butlers, are involved with: keeping your home clean, as you can now order an official Black Butler cleaning robot that’ll vacuum your floors and even engage in flirtatious banter when you call out to it.
