Hatsune Miku: Project DIVA 2nd is a 2010 rhythm game created by Sega and Crypton Future Media for the PlayStation Portable. The game is a sequel to the 2009 video game, Hatsune Miku: Project DIVA, and was first released on July 29, 2010 in Japan with no international release. Like the original the game primarily makes use of Vocaloids, a series of singing synthesizer software, and the songs created using these vocaloids most notably the virtual-diva Vocaloid Hatsune Miku.

Supercell is an 11-member Japanese pop rock band led by musician and songwriter Ryo, which formed in 2007 as a dōjin music band. The other 10 members are artists and designers who provide illustrations in album booklets and music videos. Supercell started out by making use of the Hatsune Miku Vocaloid singing synthesizer to produce vocals for songs submitted to the Nico Nico Douga video sharing website. The popularity of the songs led the band to release their independent self-titled album Supercell (2008). Supercell later signed to Sony Music Entertainment Japan and had a professional release of their Supercell album in March 2009, which was updated with more songs.
