Oz's uncle. He is easy-going and very caring. Oscar was the one who found Gilbert and brought him to the Vessalius household. Both Oz and Raven treat him as a father figure. He gets along well with Break. 

~!When he received a letter from Ada (in which she stated that she had found someone who she likes), he took Oz, Gilbert and Alice to Latowidge. They dressed as students, and snuck into the school.!~

The air of celebration surrounding fifteen-year-old Oz Vessalius&rsquo;s coming-of-age ceremony quickly turns to horror when he is condemned for a sin about which he knows nothing. He is thrown into an eternal, inescapable prison known as the Abyss from which there is no escape. There, he meets a young girl named Alice, who is not what she seems. Now that the relentless cogs of fate have begun to turn, do they lead only to crushing despair for Oz, or is there some shred of hope for him to grasp on to?

Oz Vessalius, heir to one of the duke houses, has just turned fifteen. His life is rich and carefree, darkened only by the constant absence of his father. At his coming-of-age ceremony, however, everything changes. For no reason that he can discern, he's cast into the prison known as the "Abyss", only to be saved by a "chain" known as Alice, the bloodstained black rabbit. It is unknown why was he cast into Abyss, how does Alice factor into it all, and what does the organization known as "Pandora" want with him.
