Oz somehow manages to suppress Alice's power, and confronts Phillip's father. Amid memories of his own father's coldness, Oz tells him that being by Phillip's side will be enough even without changing their past tragedies. Their conversation is cut short as Vincent Nightray shoots Grim's contractor and sends him back to the abyss. They return in Vincent's carriage and ride to the Reinsworth manor, where Alice asks Oz why he was so worked up over Phillip's father, and Vincent claims to be a blood relative of Gilbert. Break shows Vincent to the door while discussing a theory that somebody inside Pandora was responsible for allowing Grim to escape. It is clear that Break suspects Vincent.

Gilbert tells what is happened in the ten years that passed when Oz disappeared. Break tells him to go spy at the Nightray family, where he also could get information on the chain, Raven, and get Oz back from Abyss. Initially, Gil was hesitant about going with the Nightrays as Vessalius and Nightray households are rivals. In the end, he chooses to go with Break, and met Vincent. Upon their reunion, Gil reveals that he had no memory of Vincent, his younger brother. As he grew, he finally found a way to tame Raven, and ultimately establish a contract with it. This is how Gil gained his nickname "Raven".

Gil is furious that Oz has lost his hat, and they set out to find it. They were challenged into a duel in order to win the hat back, and Gil finally gets it by using the B-rabbit's power. After a brief reunion with Uncle Oscar, Alice runs away, only to meet Break and they both are caught and sent to the Cheshire Cat's (a chain similar to Alice) residence. There, Alice is trapped within her memories of fear, while Break is drawn into a mirror of his own past. Meanwhile, Oz discovers her missing and goes to consult Sharon. He ponders that Break left Emily in order to lure him to the Cheshire Cat's home. Sharon uses her chain Eques to open the path for Oz and Gil.

The Cheshire Cat is toying with Oz, who responds by making wisecracks. Oz is pulled through the mirror by Jack, and reunited with Gil. Jack asks Oz to help save Alice, who has been trapped inside a memory. Jack sends Oz by himself (upsetting Gil) into the memory of the Tragedy of Sabrie, where he sees a boy which he believes to be Vincent. Bewildered, he chases the boy and follows him to a tower where he finds Alice, dead. Meanwhile, the Cheshire Cat approaches Break within the mirror to finish him off, only to have the tables turned when Break opens his missing eye to unleash his chain, the Mad Hatter.

Oz and Alice, in her B.Rabbit form, are in the middle of a Pandora meeting. Everyone there thinks that they mean to harm the four dukes and chase them. While they are being chased, we discover that Break and Gil got back safely by using Gil's chain, Raven. But, because he used it, the seal on Alice was broken and that is why she is in her B.Rabbit form. Later, when Oz and Alice are cornered, Jack Vessalius takes over Oz's body, and speaks to Pandora, saying that Glen Baskerville is not dead, and that Oz is the key to saving them from the repeat of the Tragedy of Sabrie. It ends with Oz telling Break what he had seen in Cheshire's realm, including Vincent, making Break suspicious.

Oz, Eliot and Leo are trying to get Ada back to the school. Eliot continues to confront Oz about his willingness to sacrifice himself for others, asking him if he'd ever really saved anyone that way. Lotti releases her Chain, Leon, which looks like a large lion with a crown on it's head. When the Baskervilles catch Oz and the others a battle erupts. B. Rabbit appears and so does Jack Vessalius. Then it turns to Lotti's memorie of Jack Vessalius, over 100 years ago.

After Oz, Eliot, Leo and Ada make it out of the secret tunnel at Latowidge Academy Oz remembers to ask about the melody he heard Eliot playing earlier, entitled "Lacie". Eliot claims to have written it, then asks Oz his name. Gilbert appears and Oz starts to kick him. Eliot then attacks Gilbert, much to Oz and Gil's surprise, telling him he should be ashamed of wearing a high school uniform at the age of 24. Gil reveals Oz's name when Eliot threatens Oz, and Eliot doesn't believe him. Back with Sharon and Break, Oz and Gil seem to be angry and depressed, while Alice is eating by herself. Sharon beats Break and Emily with a paper fan repeatedly and helps Alice with her emotions. Oscar enters with wine and everyone except Oz and Break get drunk.

Oz and co. go to meet Rufus Barma in order to find out more about the Tragedy of Sabrie. He appears as a tubby old man. He refuses to tell them anything unless they exchange some information that he doesn't know and taunts Oz and Alice. Break then dispels Barma's illusions and confronts the real Rufus Barma revealing his real intention of finding out more about Break's past. Break then collapses after Rufus calls him out as Kevin Regnard, a person who murdered over 116 people 50 years ago and had previously made an illegal contract. We then find out about Break's past where he meets the "Will of the Abyss" and he has his eye taken out by her, which she gives to Cheshire. We then see young Vincent enter through the gateway to the abyss when the tragedy of Sabrie occurs.
