The main characters are Ciel Phantomhive and Sebastian Michaelis. Ciel Phantomhive is a 13 year old boy belonging to one of the noble families of Victorian England. His parents were killed and he inherited the toy company of his father. Sebastian Michaelis is the butler of Ciel, performs any work for his master and solves problems affecting England with ease and perfection. What nobody knows is that Sebastian is actually a demon.
They made a contract, in which Sebastian would be his steward and servant. The main objective of Ciel is kill the person who killed his family and Sebastian must help meet that objective. In return, Sebastian will take as payment the Ciel's soul after he is able to avenge. Ciel wears a patch over his right eye to hide the symbol of the contract agreed upon with his butler. On other side, Sebastian is committed to faithfully. This butler hidden under his gloves the symbol of the contract, which takes in the right hand.
This anime is quite dramatic and mysterious. It has some action, but is also very funny. Many characters say or do things that are funny. Sebastian does amazing things, although they appear simple. For example: making a cup of tea, prepare dinner, create a sculpture. This at first seems strange, but if you see this series will understand what I mean. I Hope you liked this post, I recommend this anime because I found it quite interesting. Greetings!
