Pandora Hearts

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, strange figures gather and prepare to carry out their scheme.

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 Abyss. Gilbert snaps out of the trance momentarily, sees one of the figures faces, and blocks Oz, who was trying to kill the intruders. Unfortunately, he slashes Gilbert across the chest. Oz is then taken into the Abyss for the sin of existing.

Oz gets pulled down into the Abyss. He explores a bit and discovers the place is like a broken toy box. He also finds out that 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 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 exclaims that he will have to kill Alice. Oz forbids it, saying that Alice is not an enemy, for it was through her that he escaped the horrible Abyss. But, that it is Break who is an enemy - someone who Oz had only seen once and was now attacking his friend. Break back's down, and blames the attack on Emily, his puppet. Oz's pocket watch then starts to act strangely. Raven comments that the door to the Abyss had opened and a chain escaped. By using Raven's chain's powers, Raven was able to control the B-Rabbit's powers from within Oz. With this power, Alice was could release her full form and defeat the chain. After the door was closed, Alice found out why it had reacted to her. The music lured her to the watch because it contained one of her memory shards. Oz then remembered that a man from another one of his visions had told him about Alice.

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.
