Event Weapon Imitation

An Event Weapon Imitation (模倣事象兵器) is a non-magical imitation of the Arch-Enemy created through advanced technology. These devices rely on atomic power rather than Magic Element to function. The Idea Engine is an improved version of these devices. These weapons create a resonance effect in proximity to a true Arch-Enemy, as it "recognises it as something similar to itself". These were made by Kokonoe after her study of the Machine God: Nirvana. Overall, the weapons aren't as powerful as Nox, however.

Iron Tager is known to possess (or be) one of these weapons, while Ex Machina: Minerva is one itself. Lambda -No. 11- possessed a more powerful version of the weapon called the Idea Engine; she gave it to Ragna the Bloodedge as she died. Arakune is also in possession of a weapon as Relius Clover installed it into him; Relius also created the Detonators which use an Event Weapon Imitation as their base.
