The haunting Phantomhive manor can be found in the English countryside, where the notorious family rules over London's criminal underworld and serves as the "Queen's Watchdog." After the sudden death of the Earl and his wife, their young son Ciel unexpectedly inherits the title, which raises many eyebrows. Despite his peculiar staff and youthful appearance, those who cross paths with Ciel and his demonic butler, Sebastian, quickly learn to steer clear of their path. As they confront various challenges that threaten both the Queen and the country, it becomes evident that Ciel and Sebastian are a force to be reckoned with. Kuroshitsuji, set in the late 1800s, uncovers the truth about the death of Ciel's parents.
