Iron Maidens are a pain in the as$. I hate having to fight that one, and you have to protect Ashely from it as well.
After you beat Separate ways, and get Ashley's knight costume, you can use her as a shield. Or, tell her to wait in the middle of a room full of ganados, because she cannot be picked up, or hurt. So they will all be distracted with her, you can pick them off at your leisure.
Great, I'm moving. Who knows when you'll see me again.
