Let's say I'm attacking against Kyuden Kitsune xp with a personality at province A. I choose to resolve province A first and take an action to move my personality to a different battlefield (province B). Does the trait on Kyuden Kitsune xp prevent my movement? I ask because it seems that the battle hasn't started yet at province B, so the trait doesn't kick in.
Kyuden Kitsune xp Your forests are maddening. Negate the first movement each battle into attacking armies at your provinces' battlefields from other players' actions.
From the rules: A. Choose Battlefield
The Attacker chooses a battlefield whose battle has not yet ended, and the next battle will be fought there. B. Combat Segment
Engaging is the time point at which the battle, and the Combat Segment, both begin. ...

The battlefields themselves exist even when not being resolved (a battlefield is a location). If you attempt to move from the battlefield at province A to the battlefield at province B during the battle (a process in time) at province A, this will be negated per Kyuden Kitsune exp's trait. It does "use up" the trait for the battle at province A, so as long as you're resolving that battle, you're then free to move wherever you like.
