For young Oz Vessalius, heir to the Vessalius Duke House, the perilous world known as the Abyss is merely a folktale used to frighten misbehaving children. However, when Oz's coming-of-age ceremony is interrupted by the malicious Baskerville Clan, who intend to banish him into the depths of the Abyss, the Vessalius heir realizes that his peaceful life of luxury has come to an end. Now, he must confront the world of the Abyss and its inhabitants, the monstrous "Chains," which are not quite as fictional as he once believed. Based on the supernatural fantasy manga of the same name, Pandora Hearts tells the story of fifteen-year-old Oz's journey to discover the meaning behind the strange events that have overtaken his life. Assisted by a mysterious Chain named Alice, whose nickname is "Bloodstained Black Rabbit," and members of a clandestine organization known as "Pandora," Oz begins to realize his existence may have more meaning than he could have ever imagined.
