Parasoul's Wunderwaffe DG-2

"So this is a Black Egrets variant of a Wunderwaffe DG-2, huh? Well, that turns out that Parasoul Renoir owns this kind of a wonder weapon, and it's made all by herself since her younger sis named Umbrella went missing and got kidnapped in the Zeltwachen Infection. Now this should come in handy."

--Su Ji-Hoon, Black Blood and Lost Sister

Parasoul's Wunderwaffe DG-2 is the Black Egret variant of Wunderwaffe DG-2 that it would be the wonder weapon of Parasoul Renoir, which it was created by herself since her younger sister was missing and kidnapped in Zeltwachen Infection.

It would be created in during Zeltwachen Infection that she survived from the zombie traitors and other zombies attack even though she lost all of 10 her soldiers when they attacked their zombie traitors and other zombies since the apocalyptic vanguard of Zeltstrich kidnapped her younger sister. And later,she escaped to a refugee camp located in Camstedt,Zeltstrich.

When she and the survivors lived in their refugge camp, due to remembering her younger sister, she even created a variant of Wunderwaffe DG-2 for not only remembering her younger sister, also even respect Edward Richtofen, the creator of Wunderwaffe DG-2 that she hope her younger sister won't become a zombie.

It would help her to find her younger sister that she would help heroes and the Survivor Brigade to find and enter Nolte Geschwefel's Castle
