Kekkaishi / Tanabe, Yellow

Yoshimori, a sixteen-year-old kekkaishi--a demon hunter who creates magical barriers around his prey--sets out to improve himself after he fails to capture a foe; and loyal demon dog Madarao is reunited with someone from his past, who tries to lure him away.

Teenage demon-hunters Yoshimori and Tokine must find a way to resolve their differences if they are to stand a chance against demon-charmer Yomi and her pet demon, Yoki, and save their school.

Demon-hunter Yoshimore Sumimura fights to get out of Kokuboro Castle alive.

Karasumori learns that the organization has sent Gen to help him patrol, and decides he isn't going to let the young man take over his position.

The Kokuboro ayakashi assault the Karasumori site to siphon its magical energies to heal their princess, and when Gen pulls out every last stop to battle them, they make him an offer he can't refuse--join them or die.

Teen neighbors Yoshimori Sumimura and Yokine Yukimura, both schooled in the art of kekkaishi, or demon-fighting, develop feelings for each other while spending time together battling evil, but their relationship is threatened by the ancient rivalry between their families.
