Pandora Hearts is an anime set in an alternate European world and is a series that spans nearly a century of history. The anime's premise centers itself around a horrific event appropriately named the Tragedy of Sabrie and the handful of characters who are supposedly involved. Enter Oz Vessalius, an heir to one of the four great dukedoms, who has just turned 15. His life so far has been rather normal for a noble of his status as he has had the privilege of living in a posh mansion, being attended to by his loyal servants, and being free from most worries. However, on his "coming of age" day, everything takes a turn for the worst. Enigmatic personas in robes deem him guilty of a "hidden sin" and choose to cast him into an alternate dimension simply known as the Abyss. Upon his arrival to this dark prison, Oz is immediately attacked by Chains, monstrous creatures who inhabit the Abyss. Just before he is devoured by one, a Chain known as Alice comes to his rescue. Who is this Alice, why was Oz cast into the Abyss, and what other trials await him?
