A unit founded in 2002 by composer Satoshi Yaginuma, with a mission stated on its own site: to bring digital J-POP back. Its history is told by vocalists — nao until 2009, Yoshino Nanjō from 2009 to 2022 (the run that made them famous), and Mao Uesugi and Hisayo Abe since 2022. With Nanjō they recorded "only my railgun", which reached #3 on Oricon, and every opening of Toaru Kagaku no Railgun: "LEVEL 5 -judgelight-", "sister's noise", "eternal reality", "final phase" and "dual existence". The catalog also has them on Black Bullet, Killing Bites and Clockwork Planet.
