Mystical forces are powerful in the region called Karasumori. For over 400 years, it has been the duty of a clan of Kekkaishi—barrier masters—to guard the land, exterminating the supernatural beasts which appear there night after night. Yoshimori Sumimura is a 14-year-old student at Karasumori School. Following in the tradition that's come down through the generations, he is the twenty-second Kekkaishi of the Sumimura clan. But he’s constantly fighting with his rival, Tokine Yukimura—his childhood friend and also a Kekkaishi—about who is the rightful heir to the magical barrier arts. Protecting people from danger while growing stronger himself, Yoshimori will battle the forces of evil again tonight!
