2012年4月30日 放送
The Paranormal Investigations Club have a summer break sleepover at the old school building to investigate another ghost story. In truth, Kirie wants to find the evil shadow ghost she saw before. Teiichi and Yuko spend the night together exploring the building, while she reveals two of the ghost stories of the school, the Ghost of the Old Night Duty Room and the Stone of Curses, were actual pranks by her. She later brings Teiichi to her favorite spot when seeing the sunrise, and is glad they are spending time together. Meanwhile, the shadow ghost appears before a sleeping Kirie. (Source: Wikipedia)
