With many questions left unanswered, Yoshimori and Tokine escape Headless Island. All is peaceful back home at the Karasumori Site...until a mysterious fissure cracks open the school grounds. Then Mt. Okubi, the largest of the mystical sites, is attacked, and its enraged guardian deity goes on a rampage! The Shadow Organization sends a powerful, polite young man to help guard Karasumori--but can he be trusted? And who needs help anyway?!
