Ciel Phantomhive is the Queen's guard dog. He works in the world of crime to take care of whatever worries the queen.
He's not very friendly. I'll tell you that much now.
He's never seen without his butler, and is always wearing his eye patch and his family ring.
His parents were killed in a fire when he was young and he was taken away and sold. He found Sebastian shortly after that and made a deal with him that Sebastian could have his soul when he killed those who took away his dignity.
