Black Butler Vol. 3 (manga)

Terrorizing its populace, Jack the Ripper has shaken London to its very core. But when Sebastian Michaelis, singular butler of the Phantomhive house, lays bare the madman's true identity, all that is left for him to do is eliminate the perpetrator in the name of the Queen and Phantomhive. But inhumanly efficient skills don't guarantee victory when the opponent is just as supernaturally gifted!

Though Sebastian may be able to save Ciel from physical harm in the battle that ensues, will the young earl ever recover from the emotional scars it will leave on his heart?
