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?

"The answer you seek lies within them." Oz Vessalius may have survived his stint in the Abyss, but he is no closer to discovering the truth behind the "sin" for which he was condemned. On the advice of a mysterious man who appeared to him when Alice regained the first of her memories, Oz, along with Alice and Pandora's Raven, embarks on a mission to investigate the site of his disastrous coming-of-age ceremony in search of answers. However, what begins as a simple investigation becomes the revelation of a harsher reality, which comes swooping down on Oz as the hands of the clock continue ticking away mercilessly...

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...

REMEMBER...WHAT IT IS YOU TRULY DESIRE--! Duldum and Duldee, two hearts struggling against each other. They are interchangeable, but far from ordinary, reverberations. The irreversible final moment closes in, a result of a seemingly hopeless wish. As if it was the beginning of the end...

Where in the world are you? This question is posed to Oz Vessalius once more. After overcoming the chains of infinite despair that bind him, the answer at which he arrives becomes a blinding light, piercing through the jet-black darkness. As though hope can be spun out of the emotions of a person's heart...

Someone once said that all they would find there was darkness that swallowed everything whole. But that never meant that light was nowhere to be found-- They finally arrive at an answer to the question of how to save their world. It is the product of many months, even years. Cruel yet kind, it is a simple formula. Now, led on by the cogs of destiny, it spells the end of but one story...as if it were no more than a ridiculous fairy tale.

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...
