9mm Parabellum Bullet was formed in March of 2004. Their name comes from their drummer, Kamijou Chihiro, who is a graduate of a soldier/finishing school.
They recorded two early mini-albums, Gjallarhorn in 2005 and Phantomime in 2006, encompassing a variety of genres, including hardcore, punk, metal, pop, and emo, accentuated by their own fast-paced sound. 2007 saw the releases of the Discommunication e.p., featuring "Discommunication" and a 25 minute live track, and The World e.p. which featured newly recorded version of songs from Gjallarhorn in addition two new tracks, "The World" and "Heat-Island." At the end of 2007 they released their first full album, Termination, after which they began their first one-man tour.
In the summer of 2008 the band released the double A-side single Supernova/Wanderland, which also included piano instrumentals of both songs, and a third song called "Wildpitch." In October the band released their second full album, VAMPIRE, and proceeded onto the VAMPIRE EMPIRE TOUR 08/09. In April of 2009 the band released their first live DVD, act I, which contained 4 concerts from different points in their career. The limited edition came with a copy of the VAMPIRE EMPIRE VIP pass and a photobook of the band.
In late spring of 2009, the band released the single "Black Market Blues."
