Yana Toboso’s ongoing manga Black Butler (Kuroshitsuji) debuted in 2006. Volume One collects the first four issues.
Gloomy twelve-year-old Ceil Phantomhive is an orphan and a tween. He is also a canny businessman: he has guided the family business, Funtom Company, towards domination of the game and candy industries.
Business success has not lifted his profound depression. He never smiles. Nonetheless his fiancée Elizabeth Midford (a fiancée at twelve?) and his servants adore him.
