A rotary multi-barrel machine gun inspired by Gley's Frenzied state, during which she unleashes overwhelming sustained fire using her Arche.
This weapon undergoes a preheating process before firing, where a specialized coating applied to the barrels, forms a thin gaseous film on the surface when heated to minimize bullet friction. Additionally, a built-in thermoelectric converter utilizes the elevated internal temperature to increase the output of the barrel rotation motor, allowing for faster firing.
However, this method had a fatal flaw. During sustained fire, the temperature would rise, causing the barrels to glow red-hot and trigger the safety mechanism. Even rotating the bundle of twin barrels connected by a central bridge to disperse recoil and improve cooling efficiency could only delay overheating, failing to serve as fundamental solution. The Magisters opposed the weapon's production on these grounds, but the weapon's developer refused to modify the design, arguing that it resembled Gley in its tendency to push itself to the limit.
Contrary to the developer's high hopes, however, Gley gave a scathing critique of the firearm that had supposedly captured the very essence of her being.
"My Frenzied state isn't anything to be proud of. It gnaws at my body and reminds me that the blood of those who took my daughter flows through my veins. Besides, "Frenzied Locomotive"... You aren't making fun of me with that name, are you?
