Moto Aikenro: Battle Range 3. Straighten Aikenro if you have moved your Cavalry Personality to Aikenro's battlefield this turn.
Does his abilty refer to moving a Cavalry personality to the current battlefield that he is at (whether he was there or not at the time), or simply that you have moved a Cavalry personality into an army he was in?
Scenario 1: Moto Kyouaku-Inu and Aikenro assign to attack one province. I resolve a 2nd province and Calvary Engage over, using Kyouaku-Inu to drag Aikenro over during the battle. Would that allow him to straighten? (Seems too good, so I'm guessing not.)
Scenario 2: I assign Aikenro to attack and Cavalry engage a personality into his battlefield. He gets sent home with the favor. Later in the same attack phase I move him into a different battlefield. Would his ability straighten him then? (I'm guessing yes.)

"Aikenro's battlefield" is evaluated at the time the action is taken, not at the time you moved your Cavalry Personality.
1. Yes, as you have moved a Cavalry Personality to the battlefield Aikenro is currently at.
2. No, unless you've moved another Cavalry Personality to the current battlefield this turn.
