Kekkaishi, Volume 28 in Bloomington, MN

Students by day, demon hunters by night!
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.
A powerful witch prepares to unleash a final devastating assault on Karasumori! Will Yoshimori be able to master his mind in time to access his full kekkai potential and thwart her? Meanwhile, his brother Masamori learns that a different type of mind control is corrupting the Shadow Organization. How can the Council of Twelve fulfill their mission to protect humanity from dark magical forces when they can't even trust each other...?
