Pandora Hearts

Oz Vessalius, heir to a ducal house, has always treated the Abyss as a frightening story for children. During his coming-of-age ceremony at 15, however, members of the Baskerville clan appear and condemn him for a baffling crime: the very fact that he exists. They cast him into the Abyss, a dark realm inhabited by monstrous beings known as Chains.

There Oz forms a contract with Alice, the Chain called the Bloodstained Black Rabbit, and finds a way back. Yet time and reality are no longer as he left them. With Alice and members of the secretive Pandora organization, Oz begins searching for the reason behind his sentence, uncovering secrets tied to his family, the Abyss, and the true meaning of his own existence.
