Supercell

supercell (written without capitalization as often as with) is a Japanese pop/rock band that formed in 2007 which owes much of its popularity to Vocaloid, and to which we owe the existence of Black Rock Shooter as the franchise is known today. The band's leader, Ryo, is both the songwriter and producer; the ten other members of the band are illustrators and graphic artists who produce PVs, art, and booklets. supercell has no official vocalist; its songs have thus far all been sung by Vocaloid Hatsune Miku or freelance singer Nagi (who made her debut on Nico Nico Douga under the pseudonym "Gazelle").

Ryo and supercell's debut was the Vocaloid smash hit "Melt", a simple love song about a shy girl walking together with the boy she has a crush on. It was first released over Nico Nico Douga in 2007, and has since become considered one of the songs which has established Miku's commonly perceived personality. It was followed up by several more releases, and as supercell gained more attention, they signed a record deal with Sony Music Entertainment. Since their self-titled Vocaloid album, most of their releases have been performed by Nagi, and she is set to be the vocalist for their second album.

supercell and Nagi have provided theme music for several extremely popular anime and games since their debut, among them Bakemonogatari, Cencoroll, and upcoming Nasuverse visual novel Mahoutsukai No Yoru. Their Vocaloid song "Kocchi Muite Baby" was used as the opening for the second Project Diva Vocaloid rhythm game. Ryo also composed "Braveheart", the theme of the Black Rock Shooter OVA, although it is performed by a different band.
