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?

As Oz Vessalius and his valet, Gilbert, are reunited with their dear Uncle Oscar, they fail to notice an alienated Alice lost in thought stumbling right into the lurking Xerxes Break. Before Alice can take heed of Break's warning of a trap set by the Cheshire Cat - a powerful, extraordinary chain - she and Break are spirited away to Cheshire's lair, where both danger and fragments of Alice's past reside. With Sharon's help, Oz and Gil find a way to enter the sealed dimension of memories, but not only do their allies await them there, so too does the man from Alice's earlier memory! Does he hold the key to the truth about Oz's "sin"?

The incuse on Oz Vessalius's chest ticks onward, but the young heir to one of the four great dukedoms directs his gaze back, seeking the facts behind a centuries-old tragedy. Intent on examining the ruins of Sablier despite warnings to scare him away, Oz and his makeshift party of explorers wander through the remnants of the former capital in search of clues to shed light upon the consuming darkness of the past. But in the yawning void where the opulent city once stood, will Oz come face-to-face with the truth? Or will he find misery the only resident...?

A century before, in Sablier, a forbidden portal was flung wide by a boy, Vincent, in his single-minded desire to protect his brother, Gilbert. And thus did that foolhardy desire lead to the corruption of that innocent boy's soul like a sweet poison... Now, as Gil, Oz, and Alice wander the ruins of the former capital, they are assaulted by illusions from the past. But how much of it is real? And how much of it illusion?

The snow-white maiden encountered once upon a time in the depths of the Abyss by the clown christened the Red-Eyed Specter...who was she really? As there are two sides to every story, could it be there are two sides to the existence known as Alice? Duke Barma may have provided a sordid outline, but Break colors the tale with vivid swathes of bloody crimson as he opens up about his past. Will these tragic truths long secreted away isolate Break further from his allies once he has revealed them?

"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...

Having returned from the infernal Abyss only to find his whole world changed, young "sinner" Oz Vessalius embarks on an attempt at normalcy after being reunited with his best friend and valet, Gilbert, whom he had presumed dead. But during a trip into town with Gil and Alice, an unexpected encounter leads Oz down memory lane...For Oz, however, the path is one covered with the most menacing of thorns. And lying in wait to assail him there...The baleful eye of his father and the echoes of cursed words Oz would much rather forget...
