Oz gets pulled down into the Abyss. He explores a bit and discovers the place as like a broken toy box. He also finds out the the place looks the same no matter where he goes. Some dolls attack him before the Black Rabbit arrives and saves him once again. First, he is fearful of the girl, who tells him to call her Alice, but he soon warms up and begins to eat cookies. When asked by Alice why he isn't afraid of her, he simply replies that too many unexpected incidents have happened to him already. He learned that he should remain calm whenever strange things happen in order to stop others from being hurt. She says that Oz is required to make a contract with her in order to leave the Abyss, and he seriously thinks about it, until he's transported away. After a fake Sharon, which is actually a Chain (a monster born in and from the Abyss) misleads him, he finally agrees to form a contract with Alice. They both leave the Abyss and Raven, a mysterious new figure, Sharon and Break, her servant, find him lying on the ground just as they were about to save him.

Oz wakes up in Gilbert's house, and ponders on the questions the Will of the Abyss had asked him earlier. Break then enters the house, and talks to Oz and Alice regarding the topic of chains, and why he and Sharon had not aged. Thus, Oz realizes that as an illegal contractor, his clock had already begun moving. Break then comments that although he can see Oz, he cannot 'see' his presence. This had annoyed Oz. A girl comes into the house and drops a letter in the name of Vincent. Later, Gilbert takes Oz and Alice outside, where her crave for meat starts. Oz stays back to wait for them to buy food. Meanwhile Alice wonders what 'parents' mean and decides to ask Oz, only to be stopped by Gil. He tells her the reason that Oz is sensitive to the topic, and why he acts in such a self-harming way. At the same time, Oz sees a group of boys bullying a child, and saves him. They begin to talk.

At Latowidge Academy, Oz encounters two students named Leo and Eliot in the library, and soon gets into an argument with Elliot. Whilst trying to avoid him, Oz and Ada are captured by some Baskervilles and taken to a secret chamber beneath the school. However, luckily for the siblings, Leo and Eliot arrive to help them escape. While in the tunnel, Eliot confronts Oz, asking him why he would give himself up so easily to save someone else, saying his sadness would just be placed on the ones he leaves behind.

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.
