It has kind of a cult following in Japan and throughout Europe, and I can see why. The animation is beautiful and so are the character designs.

The story follows a little boy named Yoshimori and his female counterpart, Tokine. They are descendents of Hazama clan who are demon slayers. They use a technique called Kekkai to capture and destroy demons. They are also protectors of the magical shrine, Karasumori. The closer demons get to the shrine the stronger they become. So Yoshimori and Tokine must capture and destroy the demons as soon as they can. Their technique traps the demons in a box-like barrier and absorbs their energy thru their magical staff. They are also accompanied by 2 eel looking dogs who help them track the demons.

Even though I only saw the first episode I am hooked. The characterization looks to be a real dynamic that I am interested in following and like I said before, the animation is gorgeous. Check it out on Adult Swim on Saturdays at 12:30 AM.
