Tamaya Ifrit

A cult is trying to summon the demon, who was imprisoned in a necklace by Gosha Tamaya, by sacrificing young girls. The police department manages to get a hold of the cult leader, and the commission officer takes the chain back home. Unfortunately, his sister brings the chain along when going on a holiday with her friends, where they set up a camp next to a castle; a castle where the demon was imprisoned in a long time ago.
