ARIA the Origination - a must watch for me.

Kara no Kyoukai - Definitely. I've liked what little I read of the novels.

Kimi ga Aruji de Shitsuji ga Ore de - The only one I'm not too sure on at this point.

Minami-ke Okawari - Not a fan of the new art style, but a given.

Ookami to Koushinryou - Checked some of the manga, and the anime looks great. Reminds me of Moyashimon in terms of content. The "slice of life" that most people aren't involved in combined with a taste of the supernatural.

Rosario to Vampire - Fan of the manga, fan of Mizuki Nana, must watch.
