Fine, next question. We have the True Ancestor Arcueid, and then the airhead Arcueid. Has she always been this way?
Nasu	No. Before, she never had a chance to show her airhead side. In the story, like Arc herself says, the airhead side of herself was the result of being "broken." By who? Shiki! Remember, the old Arc never spoke.
Takeuchi	She's not really an airhead, just kinda childish.
Nasu	Just very honest. Ahh, but... I guess that was present in her foundation.
