Hatsune Miku is the rarest kind of pop star. She is enduringly popular in her native country of Japan. She has never been photographed stumbling out of night clubs in the early hours of the morning, and never had issues with drugs or alcohol. She has, in fact, never been seen outside of her concerts at all. This is because Miku is also the fakest kind of pop star. She is a hologram.
