Ciel Phantomhive

The Phantomhive family has, for years, been well known for making toys and sweets for small children. However, they are also the Queen's watchdogs; the Phantomhive family keeps an eye on black market dealings in ways that Scotland Yard isn't able to. Ciel Phantomhive is the heir to this legacy.

Until the age of 10, he lived a normal life, with his father, his mother, and the family dog. However, on his tenth birthday, the mansion caught on fire; his parents were killed, and he went missing for a month, only to return with his smile dimmed and his new butler, Sebastian Michaelis, in tow... and a demonic contract in his right eye binding Sebastian to obey his commands.

Ciel is engaged to his cousin, Elizabeth Middleford, and lives with his five servants. Despite his young age, he runs the family company, and as such is quite busy much of the time... though he still finds time to go out investigating dubious legal matters.

At his tender age, the young earl is far more composed and mature than would be expected. He remains distant from others, aloof, preferring to spend his time on work for the company. Aside from his interest in (and incredible skill at) games, he's nigh untouchable. Or so he would have people think. Underneath that clever, bratty shell, underneath the protestations that he has no interest in childish things, Ciel is very much a hurt little boy. He's selfish, not able to fully empathize with people, and he's quite contrary to the point of pushing away things that he doesn't understand because he doesn't want to seem weak, but he cares more deeply about people than he will ever admit.
