Kekkaishi, Vol. 29 (Kekkaishi #29)

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.

When Soji is gravely wounded, Yoshimori's desire to protect his loved ones from harm leads to a startling transformation. But Yoshimori isn't the only one with an interest in Soji's survival. What role does the mysterious boy play in the ambitions of a powerful foe...?

Then, tragedy strikes Karasumori...

In the aftermath, restructuring at the Shadow Organization—the group charged with protecting humanity from dark magic—leads to a promotion for Yoshimori's elder brother. And then the boys' absentee mother turns up with a surprising agenda for both Yoshimori and the guardian of Karasumori!
