Kekkaishi, Vol. 5

A modern-day Romeo and Juliet, skilled in the art of the "kekkaishi," fight against their families' bitter rivalry and a gaggle of monsters and ghosts on the loose!
By day, 14-year-old Yoshimori Sumimura is just a regular kid going to junior high school, but by night he is a "kekkaishi," or demon-fighter who specializes in generating magical barriers around his prey before making them disappear. His neighbor is 16-year-old Tokine Yukimura, who is also a kekkaishi! Together they share the knowledge of their ancient art and their nights battling beings from the netherworld. Sounds fun, but their families don't get along, because each believes themselves to be the "true practitioners" of the art of the kekkaishi.
Will Yoshimori and Tokine friendship overcome their families' ancient rivalry? And will they be able to stop the frog-demon that's threatening their school?! Their exciting adventures and magical battles begin in this volume!
