Students by day, demon hunters by night!

By night, teenager Yoshimori Sumimura is a "kekkaishi"--a demon-hunter who specializes in creating magical barriers around his prey. By day, Yoshimori's got other demons to battle: an addiction to sweets and a seriously crotchety grandfather! Yoshimori's pretty neighbor and childhood friend, Tokine Yukimura, is also a kekkaishi, but their families are feuding over who is the true practitioner of the art.

The mysterious Shadow Organization that maintains mystical order in the world is in jeopardy! First, they set out to arrest their prime suspect in the devastating attacks on mystical sites... only to find their target permanently out of their reach. Then, their headquarters comes under fire, and one of their Council of Twelve members is slain. Even worse, a
member of the Sumimura family is accused of the crime!

Meanwhile, Yoshimori trains to control his mind with the help of...a talking cat?!
