Pandora Hearts Vol. 6
Though Oz's sudden appearance within Pandora wreaks havoc, the initially chilly reception to the prison-breaker turns more than warm when Jack Vessalius, hero of the tragedy of Sablier, manifests in Oz's body. Sensing Oz's resultant inner turmoil, Oscar drags Oz and company on a 'mission' to Lutwidge Academy, where Oz's little sister Ada is a student. But a tearful reunion ten years in the making isn't the only thing for which Oz must prepare himself; cloaked enemies are lying in wait torture Oz for answers about events a hundred years past.
