Kekkaishi

By day, Yoshimori Sumimura and Tokine Yukimura attend school. By night, they defend its grounds, where a mysterious power draws dangerous spirits. As heirs to rival families of barrier masters, they have inherited the same duty but very different ways of carrying it out.

Yoshimori's raw strength and Tokine's precision must work together as the intruders become more formidable. Their everyday quarrels give way to a larger struggle over Karasumori, the place their families have guarded for centuries.
