The results of the 24th attempt by the Albion Deslio Armory to create at combat beam rifle. The ABR-24 "Voltia" is a next-generation infantry firearm that incorporates the technology used in Bunny's voltage-acceleration suit into a beam rifle.
Unlike typical beam rifles, this weapon discharges high-powered electrical energy, and as its name suggests, has a lot to do with Bunny. Contrary to Deslin's joke that it was given Bunny's surname simply because it felt like holding and firing a Bunny, there are a lot of speculations among the armory's engineers that there must be quite a story behind it.
According to the most plausible rumor, the source technology used to develop this firearm and Bunny's suit was secured thanks to the sacrifices of Bunny's parents, Cayden and Ember Voltia, and it is generally assumed that the firearm was given the official name "Voltia" to honor their achievements.
