The STN-J is called in by the local police when a dried corpse is found. When Robin finds a dead insect on the body the team goes on a hunt for a Witch who can control insects. They find that there were two previous victims found in the same condition. The cases point to a similar rash of deaths leading back hundreds of years. Apparently, all the dead are Witches. Is the STN-J dealing with an immortal who feeds on Witches?

Dr. Kirihara is touted as being a miracle worker; someone who even can heal people with terminal illnesses. However, the ‘miracles' are really being done by another person; a doctor named Karosawa. Unfortunately, Dr. Karosawa performs these healings by using his power to take the life of someone who he feels is unworthy. It's an ethically difficult situation for the STN-J, who have been called in to stop him.
