Ryushiro
[09] Warrior
I'm sure someone here can find and confirm this, but back when Siegfried was revealed, didn't the bio they 'press released' with him state that Kilik and his companions (meaning Xianghua and Maxi, the latter who wasn't revealed yet) freed him from being Nightmare?
I clearly recall reading that.
That could mean that Raphael lost his whole large role in the story.
If I remember correctly, Sigfried regain control after the events in Soul Calibur 1 but then he turn again to being Nightmare. Then Raphael appear in the story in Soul Calibur 2 hitting Soul Edge in the eye giving Sigfried control again to struck down Soul Edge with Soul Calibur.
