The marvelous Coronian heroine Eureka has appeared out of nowhere, and within a few short days of combat she has established her position on the battlefield. Whenever she approaches a tank division, its commanders immediately give orders to retreat and try to contact the nearest air force squadron available nearby. Eureka's destructive weapon lays waste to ground forces and its blinding green flash of light is quite often the last thing a soldier sees in his life.
The hefty amount of equipment Eureka carries around allows her to create wide and powerful shockwaves which, when charged, will launch towards the enemies and sweep them from the ground. Lightly armored units will most likely not survive it, while the heavier ones and infantry will be massively damaged in the process. Because of the sheer power of this weapon and being difficult to control, Eureka usually fights alone, away from her companions, as one inaccurate shockwave could do more bad than good for the Wings of Coronia. However, if she wills it, she can quickly return to them using a nifty trick - Eureka's boots are equipped with miniature windspin engines that allow her to benefit from the speed boosts which can be provided with the Spinblade.

An easter egg can be found in Eureka's cheering animation; the word "WRYYY" with various colors will appear above her for a split second as she screams, which is a reference to the meme of the same name in the anime JoJo's Bizarre Adventure. Her pose is also similar to DIO's as he screams in victory.
