Hi, I've been desperately trying to identify this very old movie (series?) I watched when I was a kid, so I am guessing it must be from the 80s. All I can remember it's a young teen stumbling upon a village where he meets a mysterious girl who spents most of the story in a flowery swing or playing the harp. I vaguely recall her being the daughter of a demon/the devil, who's using her to get at the protagonist.
Any help would be greatly appreciated!
