5 - 4: Shadow of Linked Chains

Matoba brings Natsume to one of the Matoba clan villas to attend the exorcist meeting. Natsume learns that a mask yokai called "Magatsumen" is controlling people and disguises himself as a shiki in order to test attendees if they have been possessed. By following a strange spring sound, Natsume finds the culprit behind the mask possessions and drives the yokai out. Matoba shoots the yokai with an arrow to exorcise it.
