So, I was replaying Final Fantasy 7... I'd just gotten to Kalm and went to check out the weapons shop. And, much to my surprise, the new weapon for Aeris (or Aerith, if you're a KH fan) was the Full Metal Staff.
Unlike her usual quarterstaff, this one has a blade at one end. As near as I can tell it's pretty close to Ed's weapon. Do you think Arakawa Hiromu's a FFVII fan? ^_^ (As a side note, Mangaka Matsushita Yoko is a FFVII fan... Nearly the entire crew of the game shows up in the background of a panel of the Yami no Matsuei manga)
