The Abyss had always been a fanciful fabrication that young Oz used to manipulate children into behaving themselves, as befitting the future ruler of the esteemed Vessalius Duke House. But when the nefarious Baskerville Clan sets their sights on him during his rite of passage, his pampered existence is summarily shattered. Oz is forced to confront the reality of the Abyss and its resident "Chains," now fully convinced that they are more than mere fairytales. The manga series Pandora Hearts charts Oz's otherworldly odyssey as he grapples with the strange happenings in his life. He is aided by Alice, a mystifying Chain also known as the "Bloodstained Black Rabbit," and enlists the covert guidance of Pandora, a shadowy organization. Oz discovers a sense of purpose that he never knew existed, leading him down an unexpected path.
