Pandora Hearts by Jun Mochizuki

Really good. Most of its characters are based off Alice in Wonderland, but there's a lot of action, so it's interesting but the story is confusing. At times I'm like " What? I don't get it! What just happened?" But other than that it is pretty good. The art is excellent too.

Summary- Master Oz is the son of a successful father, but his father completely ignores him. When the day comes that Oz must go through his coming-of-age ceremony, hooded men appear out of nowhere and say that his sin is his very "existence." He is banished into the abyss, where he is trapped forever. He mankes a contract with Alice, a girl nicknamed " the bloodstained black rabbit," to get out of the abyss. When they get out, they are confronted by three people part of an organization called Pandora. Those three people tell Oz that he is the key.... But to what?? Read and find out!
