Rumors of a new kind of mushi have brought Ginko out to visit another master, one who’s been studying the discovery for some time. But upon his arrival, Ginko is disturbed to find the villagers preparing to destroy the mushi, scorching the mountainside in the process. Unable to persuade the local master to stay her hand, Ginko is detained until the deed is done. Realizing the true danger at last, he fears the cure may be far worse than the curse, the fire releasing an even deadlier threat.
