Pandora hearts / Mochizuki, Jun

Fifteen-year-old Oz Vessalius is punished for a sin he knows nothing about and thrown into an inescapable prison, but an encounter with a young girl named Alice brings Oz a glimmer of hope.

In an effort to learn more about the tragedy of Sablier, Oz and his friends seek an audience with Duke Rufus Barma, but the story the Duke reveals is not about Sablier, but instead the more recent and shocking events of Break's past.

As the incuse on Oz's chest ticks away, Oz and his companions push on into the ruins of Sablier in search of information about the past, refusing to be scared off by the warnings they receive.

Having escaped from the prison known as the Abyss, Oz Vessalius, Alice, and Raven of the Pandora organization travel to the site of Oz's coming of age ceremony to investigate the crime for which he was imprisoned, but, once again, harsh reality awaits him there.
