She is the best sniper in the Empire and also one of the first successful test subjects of the Empire's "Girl Project". The Empire specially tailored the "Fox Hunter I Multi functional Sniper Rifle", "My Teeth Tactical Dagger", and the high-power "Apocalypse" lightsaber for her.

The giant cross containing terrifying power is Vivian's iconic weapon, it is not a technological product of the empire, and no one has ever known its origin. I only know that once the ZERO system is activated, it becomes a solid barrier that nothing can invade. It is said that it is also the key to unlocking destruction, with the power to destroy the heavens and the earth. It has only been used once in that great war of destruction, and its terrifying power has made the empire seal it, except for Vivian's teammate Liling LIRLY BELL can unlock this seal.
