Kekkaishi (ongoing)

Overview
Just your average school-boy-who-can-see-ghosts-and-has-special-powers -to-extinguish-them show. It's not totally boring, but it's a little predictable and not very original, except for the powers that they use: all they can do is make blocks (and a few minor other things). But they use these blocks in a lot of different ways to make them useful: creative with blocks ~_~

Summary
Yoshimori Sumimura is a regular school boy who extinguishes evil from the school grounds at night. This is because it is the duty of his family to protect this place that somehow makes spirits that come there stronger. But the thing is that Yoshimori’s family is not the only family that claims to have the task of protecting the holy school grounds. Their neighbors, the Yukimura family also protects the school when evil spirits seek to become stronger. This usually means that Yoshimori from Sumimura family and Tokine from the Yukimura family are send out and compete with each other to beat evil first. Of course there is also the school part of their lives and Tokine is two grades higher than Yoshimori. They try to hide the fact that they see each other almost every night, but do not always succeed.
