Black★Rock Shooter is a hero song of same name who performed by Miku Hatsune. Black★Rock Shooter tells of the narrator's despair and hopelessness as they wander aimlessly, searching for something important to them that they presumably lost. Eventually the narrator gains new hope and decides to move on into the future with courage. The video for the song became massively popular, featuring Black★Rock Shooter traveling through a bleak city and countryside, riding a motorbike and wielding weapons. With little explanation as to what she is, it spawned a Fanbase that is dedicated to find the answers.
