After Kaede is abducted, Momoko and Rena formulate a plan to get her back with Iroha tagging along to help. Also joining their group to help them is Yachiyo, the girl that Iroha encountered previously on her first visit to Kamihama.

Iroha and Yachiyo confirm the rumor of the Séance Shrine and see the people they wished to meet. Unfortunately, they turn out to be impostors and are attacked by the monster of the shrine. As they fight, Iroha's Soul Gem begins to darken.
