A mysterious nobleman living in luxury, The Count approaches and befriends Albert in Luna as the first step in his plan of revenge against the people who once betrayed him.
The Count's previous identity was Edmond Dantès, a sailor who worked for the Morrel family's shipping company. Edmond was imprisoned in the Château d'If on false charges, and it was there that he met Gankutsuou (known as The Ruler of the Cave in Animax's English adaptation). In exchange for the strength and means to gain revenge, he allowed the cold-blooded demon to possess him. Because of Gankutsuou, he is afflicted with an odd condition which causes his body to be crystalline, revealing his bones and internal organs.
If you enjoy the classics like a true lit geek, then you'd be happy to know that there are several anime series that are inspired by stories written in the unforgotten past by authors that would forever live on.
