As the social calendar of high society unfolds and the season nears its end, London is engulfed in fear. Someone has begun to stalk the women of the night and paint the city red... with their blood. The name echoing everywhere is 'Jack the Ripper' - and as a result, the name that Queen Victoria utters is Phantomhive.
Called to London to clean up the chaos caused by this madman, Ciel Phantomhive arrives with his exceptional butler, Sebastian, by his side, to serve him tea, polish his silverware, and... investigate a serial killer.
With the help (and occasional interference) of some of the many acquaintances of the Phantomhive family, little stands in the way of the young count revealing the truth behind this mystery. However, one question remains... can he handle the overwhelming truth behind it?
