Break gives Oz, Alice, and Raven their first mission. They are sent to a nearby town in search of an illegal contractor, someone who makes a contract with a chain without the permission of Pandora. While there, Alice goes missing and Raven goes to look for her. Alone, Oz sees a young girl selling flowers. When the trio have dinner, Oz realizes Raven's other personality, which reminds him of Gil (especially the black hair and golden eyes). Raven then informs Oz of why people become illegal contractors - to change the past. As Alice falls asleep, Raven and Oz leave to finish their mission. Meanwhile, Sharon and Break are discussing the mission and how they had kept some information secret. Alice is soon awakened by an attack by a chain, whose contractor turns out to be the girl that was selling flowers. As Raven shoots the chain, the girl's clock seal makes a full rotation. She gets drawn into the Abyss, screaming. Oz tries to save her, but is restrained by Raven, to stop him from being dragged down into the Abyss again. On the ride home, Raven informs them that the only way to stop Oz from being dragged into the Abyss when his clock makes a full rotation is to kill Alice, which initiates an argument between Alice and Raven. The episode ends with a death god laughing inside the Vessalius mansion.

After seeing a murdered Alice, Oz is devastated. Because of his shock, Oz's clock hand moves again, and he begins to destroy Cheshire's dimension using B. Rabbit's power. He justifies his actions by saying that it was for Alice and he'd take that fear away from her, even to the point where he says that he would kill Alice, but only says these things because he's in a trance. During that time, Jack sent Gil to help Oz, which he does. Meanwhile, Break is overpowering Cheshire using Mad Hatter. Break takes the truth of the Tragedy of Sabrie and Alice's memories in the form of Cheshire's bell. After Oz realizes he came to Cheshire's dimension to save Alice, he and Gil find her in chains on a staircase contemplating about herself. As Oz climbs the stairs, he tells Alice that it doesn't matter if she's human or a chain, being "Alice" is fine and saves her. Cheshire becomes angry and abandons his human form for a monstrous black form and leads Break to Oz, Alice, and Gil. Cheshire is destroying his dimension for the same reasons that Oz mentioned earlier. Break easily defeats Cheshire, and Alice realizes that Cheshire was once her pet cat. Eques appears to return the group to their world. However, Break and Gil get separated from Oz and Alice and are left in Cheshire's dimension. Eques brings Oz and Alice back to their world, but they interrupt a Pandora meeting with Uncle Oscar involved and Alice is in her B. Rabbit form.

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, Alice, and Gil have been seeking chains for memory fragments for a while now with no success. Ada visits Oz during her holiday break and finds dozens of Pandora guards escorting him; Jack had ordered for Oz's protection when he last appeared (Episode 16). Oscar sees Ada making eyes at Gil and drags him off. Break directs the guards to another task, since he doesn't like being watched. Sharon believes that if the Baskervilles wanted Oz dead, they would have taken care of him already. Gil visits Vincent to ask about Sabrie, but Vincent denies remembering anything. Independent of Gil, Oz and Alice also try to see Vincent but are immediately turned away by Echo. Vincent tells Echo that no one needs to know what happened. To find more clues, Oz and co. visit the mansion where his coming of age ceremony was interrupted. He reenacts the ceremony in the hopes of discovering something. Trump cards appear and attack Alice, who defeats them. The city of Reveille is on fire.

The group hurries to the burning city, where a large-scale Chain attack is taking place. Gil thinks the Baskervilles are to blame for the Chains coming loose, but Alice tells them the Will of the Abyss is calling out, which is upsetting the balance of the Abyss. Gil unleashes Alice's B. Rabbit powers and each of them joins the fight. Oz saves a boy from a burning building and as the building falls to the ground, Alice saves them and the boy is returned to his mother. Oz collapses and Alice reverts to her other form since she had used too much power. Break says it's time to get serious and takes out his Mad Hatter, which causes the Chains in the area to crumble away. After every Chain is gone, Break falls to the ground. While Oz and Alice sit in an abandoned house and talk, a Chain erupts from the floor. Alice and Oz run away and bump into the Baskervilles, who help them destroy the Chain. When asked why, the Baskervilles claimed to be under orders, and said they would need Oz's power. Many more Chains appear and are killed by the Chains of Pandora, which finally come. The reinforcements are soon killed by one giant Chain. B. Rabbit faces the Chain but is unable to defeat it, and in the end the Chain turns to stone and Oz and Alice see one of Alice's memories.
