Kekkaishi

By night, junior high student Yoshimori Sumimura is a “kekkaishi“–a demon-hunter who specializes in creating magical barriers around his prey. By day, Yoshimori’s got some other demons to battle: an addiction to sweets and a seriously crotchety grandfather! Yoshimori’s pretty 16-year-old neighbor and childhood friend, Tokine Yukimura, is also a kekkaishi, but their families are feuding over who is the true practitioner of the art. Won the 52nd Shogakukan Manga Award in the Shounen category.
