Oz Bezarius (also spelt Vessalius) spends his 15th birthday running away from the maids with his younger sister, Ada and servant, Gilbert. They hide out at Oz's secret spot, where he accidentally falls through the ground leading to a hidden cemetery. There's only one grave there, and a pocket watch is attached to it. As Oz grabs the pocket watch from the tomb, he sees a vision of a homicidal girl before being brought back to reality by Gilbert. While he prepares for his coming of age ceremony, s
Oz leaves for the ceremony, while Gilbert is possessed by one of the death gods. As Oz makes an oath during the ceremony conducted by his uncle, Oscar, the clock (which was silent for 100 years), suddenly strikes. This brings the strange figures inside the sanctuary, preparing to take Oz away. The possessed Gilbert tries to kill Oz, and succeeds in stabbing him. Meanwhile, the girl from his vision (called Black Rabbit by the death gods) comes and fights them to save Oz from being pulled into the
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
Oz wakes up to see Raven, Sharon and Break. Upon seeing Raven, Oz calls him Gil. Raven's appearance is similar to those of Gilbert - having black hair, and golden eyes. Break explains to Oz about Pandora(an organization who's objective is to find out anything they can about the Abyss), the residents of Baskerville (their enemies), and their main goal. Alice then possesses Oz and takes Sharon hostage in order to escape, but Break stops her by forcing her from Oz's body. After her release from Oz,
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 contra
Oz decides to return to the mansion, where his coming of age ceremony took place. However, upon arrival, the state of the mansion appears deserted and worn down, unlike the rich glorious mansion as Oz remembers. At the same time, memories pertaining to Gil are recollected, including Oz's insistence of his role as master protecting his servant. As Raven scouts the mansion on his own, he's ambushed by Doldam's marionettes. During the fight, it is revealed that Raven is an older Gil and that ten ye
Oz manages to shock Raven back to himself, and his gun fires, but at Zwei instead of Oz. Oz follows Raven, who claims that he is no longer the Gilbert Oz once knew, to the place where they found the pocket watch. Oz convinces Gil that he won't let him go even if he's joined the Nightray house (an enemy of Bezarius). Oz goes back for Alice, and on the way to the grave they catch a glimpse of one of Alice's memories, and are drawn into a dream dimension where they are confronted by the Will of the
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 t
Oz saves a boy named Phillip, a kid from a noble family that just became poor. A flashback came to Oz when Philip asked about Oz's parents. 10 years ago, young Gilbert was about to ask why Oz's father couldn't talk to him. He responded that Oz is too filthy and unfit to be his son. After three days in the dungeon, Gil apologizes to Oz for interfering in his life, but Oz says it doesn't matter and accepts the fact that his father just hates him. After the flashback, the girl how brought the flowe
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
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
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 a
Oz and Gilbert arrive in Cheshire's dimension and are attacked by Cheshire, only to be temporarily rescued by Sharon's chain, Eques. As they try to escape from Cheshire, he catches up with them, slashes Gil(who falls off the stair railings) and attacks Oz. Cheshire tells Oz that Alice purposely tore up her memories of her own free will and that this dimension is made by Alice's memories. Cheshire also reveals his duty of protecting Alice's memories so that no one can find them. Gil later regains
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
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. Bre
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
Break goes to save the kidnapped Sharon from Vincent, but in doing so, he has to destroy Cheshire's bell (the truth of the Tragedy of Sabrie). Vincent poisoned her as well so Break would have to do what he wanted quickly. He holds the antidote over the edge of his balcony, calling Break a fool, but as it falls, Echo saves the it. Meanwhile, Oz learns about Break's past, and how the Rainsworths found him at the Abyss' door and his acceptance. Later, Oscar receives a letter from Ada from Latowidge
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 lea
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
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 ha
Why would Vincent kill Alice's cat Cheshire and then kill her? As Break, also known as Keven Regnard, wakes from his feinting spell, he tells Rufus Barma, Oz and co. all he knows. In the Will of the Abyss's room, Vincent shows up along with Gilbert in his arms. After Vincent collapses, Will of the Abyss starts yelling at him about how he should be dead then she starts to cry. She looks at Break and asks who he is then screams that it's teatime. She says she can't wait for her playdate with Jack
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 visi
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 rever
Oscar tells Oz that his father has been out of reach for ten years. Sharon and Break discuss what happened earlier, and Break says Oz really does have the power to control the Abyss and that the Will of the Abyss had a "special feeling" towards Jack. Break tells Sharon that there's a rumor about Oz being the reincarnation of Jack, and he also tells her they may have to reconsider the Baskerville's true intentions. Gil, Oz, Alice, and Oscar return to Oz's home and at dinner Oscar reveals that bef
