She' not as apparent as the other two but I blame it more on the limitations of technology. She's a lot like Belledandy in that her personality is highly idealistic and she's fawned over by Cecil and Kain despite having no real traits about her that state why she is truly important to them. She's probably not as bad as Aerith, Rinoa, or Yuna but she is pretty underdeveloped for a character who figures into the story as much as she does.
