You can try Chūnibyō Demo Koi ga Shitai! It's not exactly fantasy based, but more like this girl thinks she's in some fantasy world. Or relates reality to a fantasy world. I just started watching it myself, but it's really cute and Iove it so far!

The anime started airing in October, but it might've come from a light novel, not an anime. :P

But a good fantasy type manga is Blue Exorcist if you haven't watced/read it. I'm currently reading this one too. :)

how about

Magico (IWAMOTO Naoki)

Sixteen-year-old Emma finally arrives at the capital city Hawk Eye after escaping from being held captive for her entire life. But as soon as she arrives, every man in the city, including the king, falls madly in love with her. She is about to be forced into marriage, but is saved by a sorcerer. The sorcerer identifies himself as Shion, one of the youngest and most talented in the nation. They have met before, but Emma has no recollection. Shion explains to Emma that she is cursed with the Ekidona, a mysterious magic that happens every 500 years where a girl is born with her heart packed with such powerful dark magic that it has the potential to destroy the world. With such power, one could rule the world, and Shion explains to Emma that people are going to try and hunt her down to get her heart. However, Emma is told that there exists a ritual that will rid her of the Ekidona curse but doing so will require a long and arduous process. The first of that being Emma and Shion will have to marry each other...
