"The plot is a typically spooky affair; every ten years a special ceremony is held at a sacred shrine on Rougetsu Island, located south of Japan's largest island, Honshu. One year though, something bizarre occurred. During a very traditional Japanese concert, five girls mysteriously vanished without a trace. Little did people know, the five girls were in fact being held hostage in a haunted house on Rougetsu Island.
Eventually a police officer by the name of Choushiro Kirishima managed to rescue the girls from Rougetsu Island and return them to their homes. During the time the girls had suffered from a unique type of amnesia; everything about their abduction was forgotten, however all other memories remained intact. Though the amnesia affected the girls' emotions, they seemed to have settled down after they moved away from the haunted island. Years passed and the girls remained blinded about the incident."
