In Yamane Akio's family, everyone seems to die early, and other relatives talk about a curse. Soon after his grandfather's death, Yamane comes down with an incurable disease, and in desperation he remembers his grandfather's last words -- that somebody was watching over them. After finding an odd fossil tooth that his grandfather kept, Yamane accidentally summons a guardian spirit, who promises to cure him. Maybe he should be pleased, but this guardian has some strange methods for healing.
