Originally, Black★Rock Shooter was a character created by an artist known as huke, among plenty of other material that he uploaded to his Pixiv profile. One fateful day ryo, leader of Vocaloid synthesizer band Supercell, approached huke to create a song after having been inspired by his work, while also inviting him to join the creative team of the band. This way, the two collaborated on a music video, with huke making some small adjustments to Black★Rock Shooter's design and creating the version known today.
