The game begins with your character, whose family has just moved to the area, entering his new school for the first time. After class, you accidentally run into a conservative-looking girl wearing glasses. She introduces herself as Mizuho, but you can't help but notice her striking resemblance to your dream pop idol, Miho Nakayama. You pick up a good-luck charm Mizuho dropped to give back to her, then make a startling revelation - your photographer brother took a picture of Miho carrying the exact same charm! You go to the music room to confront her with this evidence - and this is where the true challenge of the game begins.
