His Butler, Time Travel (Kuroshitsuji)

Ciel Phantomhive is given a new case from Queen Victoria. However, this is the most perplexing and unusual case yet. The young Earl is to find that he is dealing with an unknown and mythical creature. During his investigations, Ciel and his butler somehow find themselves in 1980's London. They enter a strange new age of Brit punk rock, anarchists, and a shifting mindset amongst the English society.

The pair attempt to find ways to return to their own era of the 19th century London. Butler and master must guise themselves as modern day Londoners in order to fit in until they return home. It is when they venture into the modern world that they discover more than they bargained for.

Will Ciel and Sebastian solve the case? More importantly, will they return to their own time?
