Senior Private Namie Portman is an inexperienced Trail Krieger pilot and is the newest recruit of the Arandas Army's 8th Autonomous Unit. She is a good test pilot, her profile being used as modeling data for the Seiran, but her lack of actual combat experience handicaps her.
She personally knows Tokimune, being his underclassman in their mobile weapons study course, and gets along with him pretty well. She is shown to always carry lollipops and frequently offer it to others.
