Kekkaishi, Vol. 5: Kekkaishi, cartea 5

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.

Karasumori, the magical area that Yoshimori and Tokine have been assigned to protect, is a place of mystery and wonder. Beneath its surface lurks Lord Uro, a fantastic donut-loving creature who only appears when he needs a helping hand with home repairs. Yoshimori has been assigned the task of handyman--the only problem is that Uro's home lies in the depths below Karasumori, where the magic is strong enough to have ill effects on humans.
