Kogane is a ghost girl who shows up in a notebook that Ranma, Akane, and Kuno buy from the Furinkan High school store. She's best known for singing a song that's supposed to point the way to treasure—though it turns out the "treasure" is just a stuffed raccoon doll she'd lost ages ago. The whole thing plays out like a typical Ranma ½ side story: mysterious setup, group investigation, and a punchline that deflates the drama.
