Gerhard Schildenstein

"Well, that's Gerhard Schildenstein alright. He's the one paratrooper and commander of the First Werman Reich Airborne Brigade who once killed Vitale Medici during the First Schädeltöten Assassination, along with the ten top-ranking members of the Medici Mafia. Guess he would've been such a daring and handsome man by right now. Just for the heck of it."

--Su Ji-Hoon, Schildenstein

Gerhard Schildenstein is the commander of the 1st WR Airborne Brigade, was the rat paratrooper of Werman Reich and was the one who killed Vitale Medici.

Only happened in during USRAC War and First Schädeltöten Assassination that he will be lead his members of 1st WR Airborne Brigade to assassinate Vitale Medici and 10 high-ranking members of Medici Mafia.

Maybe he was have killed Vitate by his Combat HK33 with bayonet that he and his members were finished Vitale's crime and caused Filia's parents escaped to Inkwell Isle.
