Siegfried had played host to Soul Calibur and, ultimately, destroyed Soul Edge. After that epic battle, the knight returned home and enjoyed a brief period of peace. But deep down he knew his work was not over; the cursed sword's minions—the malfested—remained a serious threat. Realizing he couldn't stop them alone, Siegfried gathered his staunchest allies from his old clan known as Schwarzwind, he reformed the clan of thieves into a clan of mercenaries.
One day, after more than a decade of service protecting humanity from the malfested, Siegfried discovered that Soul Calibur had transformed into a new one-handed sword—a clear harbinger of Soul Edge's return. A new champion to wield Soul Calibur would need to be found; Siegfried assigned the task to Z.W.E.I., a wandering swordsman who had joined his mercenary group.
