A television game show sends Ikko Satonaka and the priestesses of Saienji Temple, among them Chitose Nanbu, Haruka Amanogawa, and the Sugai sisters Hinata and Sakura, on a trip to a secluded hot-spring inn. Once they check in, every woman in the group starts sleepwalking through the night, leaving Ikko as the only one awake to keep the situation from spiraling into chaos. This one-episode special extends the original TV series with an overnight bonus story at the inn.
