Possible? I'm betting it's a Nutaku thing though, because Amon has at least 1 or 2 lines of dialogue that I heard, and more that were unvoiced. Honestly it sounds like bad porting/programming, though it might not even be a Nutaku thing, and rather is a DMM thing. But I KNOW i heard amon at least once (she's my fav lol) but not all the time.
