Pandora Hearts volume 18 features story and art by Jun Mochizuki.

The tragedy that befell a bustling city a hundred years earlier. Eyes of ill omen. Stone seals. The warped gears that have continued turning since long ago play out a requiem for one who was much loved. The solemn sound of the dirge colors the world that hears its notes a melancholy gray... as though it was always meant to be.
