Amaya frowned a bit, as she had the hold locked in but Haruka's struggles showed she was not about to let Amaya have her way with her so easily as she began to turn her body and by extension Amaya's to a position more favorable to the nurse. Amaya had to decide now, as her grip began to be slapped away bit by bit by Haruka's free arm whether to try and double down on the hold to fight off the attempt or make a bit of a gamble.
And deciding she needed to try and get somewhat bold to gain an edge, she opted to gamble. She would let go of the hold and allow Haruka freedom of both arms, her aim now to try and use the moment to shift from an armbar to headlock as she aimed to try and pull Haruka's head to her chest and secure a side head lock attempt to shift position back to a more favorable one. Haruka would have both arms free, but if she could get this move locked she'd be able to keep control.
