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.

As the battle for Karasumori and the Shadow Organization rages on, Yoshimori may have no choice but to fight side by side with his absentee mother. Can he trust her...? Then, the witch Kakeru returns to unleash magic powerful enough to destroy the entire world!

Meanwhile, Masamori begins his bid to take back the Shadow Organization and Tokine sets off for a private meeting with...a guardian deity?!
