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.

Yoshimori couldn't care less about catching demons...until he realizes that his apathetic attitude is taking a toll on his friendship with Tokine. Just as he decides to take matters into his own hands, a couple of amphibious demons and the pesky ghost of a pastry-chef show up to complicate matters!
