Butler Sebastian Michaelis works with his 13-year-old master, the earl Ciel Phantomhive, to do the dirty work of “the Queen’s guard dog” in nineteenth century England’s gritty underworld.

One day, Ciel receives a letter from Queen Victoria telling him that several students at Weston College, one of England’s top public schools, have seemingly disappeared… including a relative of hers named Derrick.

And so Sebastian and Ciel infiltrate Weston College to get to the bottom of the matter.

What truly happened to these students?
