The Ghost of Maiden's Peak

After leaving Acapulco in search of Saffron City, our heroes finally arrive at a small port town in the middle of celebrating a summer festival. In order to recover from their hard journey, Ash and his party decide to participate in the festival. Team Rocket’s interest in the festivities, on the other hand, is purely monetary. Brock and James are both bewitched by a picture scroll shown in a shrine open only on the day of the summer festival. The picture depicts a beautiful young maiden in a scene from the legend of Maiden Rock—a point on a cape near the town. According to the priest’s explanation, the girl in the picture lived 2,000 years ago, and awaited the return of a lover captured in battle, until she finally turned into stone. Every year at this season, the ghost of this girl steals the spirit of a young man and this year it is James’ and Brock’s turn. What could the ghost possibly be after? And what is its true identity?
