Pandora Hearts
2010(?)
Kato Takao
Yes there's a manga (which, in my opinion, is better)
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.
Its very suspenseful and everyone is trying to figure out how the "Tragedy of Sabrie" happened and a few other things that I won't spoil.
