PandoraHearts, Vol. 9

The incuse on Oz Vessalius's chest ticks onward, but the young heir to
one of the four great dukedoms directs his gaze back, seeking the facts
behind a centuries-old tragedy. Intent on examining the ruins of Sablier
despite warnings to scare him away, Oz and his makeshift party of
explorers wander through the remnants of the former capital in search of
clues to shed light upon the consuming darkness of the past. But in the
yawning void where the opulent city once stood, will Oz come
face-to-face with the truth? Or will he find misery the only resident...?
