Kekkaishi, Vol. 11 (Kekkaishi #11)

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.

Tragedy has struck the Yoshimori Site, and each of our friends attempts to cope with their grief alone. Tokine searches for a secret way into Kokuboro's castle, Yoshimori trains for an ultimate confrontation, and Masamori returns home with a regiment of his Night Troops, leaving his little brother with no room of his own. Unfortunately, before long, one of our three heroes is in need of a rescue...
