Pandora Hearts, Vol. 72008

The past holds everyone in its thrall, and Oz, Alice, Raven, Break, and their acquaintances are no exception, especially as recollections of the tragedy of Sablier elude even those who were present. Indeed, with his own body playing host to Jack Vessalius, the hero of Sablier, the likelihood of Oz escaping the past seems nigh impossible. But given a renewed lease on life by Elliot Nightray - the legitimate heir to the Nightray dukedom, of all people - Oz is eager to keep moving forward by learning all that he can about the events that came to pass all those years ago. To this end, he and his friends seek an audience with another of the four great dukes - Duke Rufus Barma. But it is not a glimpse into a hundred-year-old disaster that is revealed to them in the Duke's presence, but rather one into Break's lamentable, shockingly unforgettable past...
