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 and Tokine have dedicated their young lives to protecting the Karasumori Site. Now its profoundest secrets finally come to light...
