The original line-up of the band consisted of 真緒 (Mao) on vocals, 剣 (Tsurugi) and 美月 (Mizuki) on guitar, 亜季 (Aki) on bass, and Sora on drums. The band released two maxi singles, 黒衣の下の欲望と、苦悩の果てに視た百景の百合達 (Kokui no Shita no Yokubou to, Kunou no Hate ni Mita Hyaku Kei no Yuri Tachi), and 溺哀 -dekiai- (-dekiai-) in 2005. Sora left the band due to musical differences later that year. The band recruited 景 (Kei) as their new drummer and soon released their first mini-album, The Trend Killer, in May 2006. Since then, the band has been successfully producing new music, rereleasing many works due to high demand. Sadie's first PV of the song "Meisai" was released along with the mini-album, THE SUICIDE MACHINE. Sadie completed their promotional tour for THE SUICIDE MACHINE in December/January with their finale, "THE SUICIDAL APPLICANTS" at SHIBUYA O-WEST. The band released their first live performance DVD for this show on 2007/04/18.
