She was the Empire's finest sniper and one of the first successful subjects of the Empire's "Maiden Project." The empire custom-tailored for her the "F.O.X. Type-I Multi-Functional Sniper Rifle," the "My Tooth" tactical daggers, and the high-output "Apocalypse" lightsaber.

The huge cross, imbued with terrifying power, is Vivienne's iconic weapon. It is not a product of the Empire's technology, and no one has ever known its origin. All we known is that once the "ZERO System" is activated, it becomes an impregnable fortress, impervious to all attacks.

It is said to also be the key to annihilation, possessing the power to destroy everything. To this day, it has only been used once, in that cataclysmic battle at the end of the world. Its power is so terrifying that the Empire sealed it away, and only Vivienne's team mate, Lirly Bell, can unlock the forbidden power.
