Pandora, now under the control of Leo and the Baskervilles, bears witness as the truth of the being known as Oz Vessalius is exposed for all to see. Amidst the warped tragedy that plays out mercilessly, one who has lost everything catches a glimpse of the ridiculous fairy tale contrived by a living ghost, as though a forbidden box has just been opened...

What I have granted them...is the "possibility" of survival. "I want you to be 'happy.'" One man's parting wish succeeds in awakening Oz's heart, long held captive in the depths of his own soul, as though breaking all the chains that bind him...

Once, following the tragedy of Sablier, Jack Vessalius made a valiant sacrifice to stop his best friend, Glen Baskerville, by allowing his body to anchor a set of seals by which Glen's soul was confined. But now these seals, long guarded by mages under the watchful gaze of Pandora, are being smashed one by one at the hands of the Crimson Shinigami, whose aim is to return their master to his once-whole state. And so, the fragile peace achieved over the last century begins to writhe, like a horror released from Pandora's forbidden box...

Guided by Jack Vessalius, the man from Alice's memories, Oz wanders back into the world of lost memories in search of Alice. There, he stumbles upon the devastating tragedy of Sablier, the century-old disaster which sent the old capital into the Abyss, an incident of which no one has any recollection...except Alice, who was there?! When Oz discovers the truth of the memories Alice so desperately wants to forget, the powers of the B-Rabbit will spiral out of control and threaten the lives of all who are trapped within the dreamlike dimension, including Alice herself...

"What those people are looking at...isn't me." Though Oz's sudden appearance in the midst of Pandora wreaks havoc, the initially chilly reception to the prison-breaker runs more than warm when Jack Vessalius, hero of the tragedy of Sablier and the man from Alice's memories, manifests in Oz's body. Sensing Oz's resultant inner turmoil, Uncle Oscar drags Oz and company on a "mission" to Lutwidge Academy, where Oz's little sister, Ada, is a student. But some carefree fun and a tearful reunion ten years in the making is not all for which Oz must prepare himself: crimson-cloaked foes are lying in wait to torture him for answers about the events of a hundred years ago...

The air of celebration surrounding fifteen-year-old Oz Vessalius's coming-of-age ceremony quickly turns to horror when he is condemned for a sin about which he knows nothing. He is thrown into an eternal, inescapable prison known as the Abyss from which there is no escape. There, he meets a young girl named Alice, who is not what she seems. Now that the relentless cogs of fate have begun to turn, do they lead only to crushing despair for Oz, or is there some shred of hope for him to grasp on to?
