Pandora Hearts volume 13 features story and art by Jun Mochizuki.

Oz Vessalius makes his high-society debut at the manor of Isla Yura intending to investigate the potential location of one of the stone seals that Pandora seeks. But over the festivities and the secrets that swirl behind the masks of the merrymakers hangs a cloying scent of intrigue. When the blood-blackened hand of a demon unexpectedly descends on those gathered, a waltz of madness begins... as if heralding anew an all-too-familiar tragedy.
