Run was a member of the Jaegers and Esdeath's right-hand man. He was calm, collective and polite and had never been shown to raise his voice or give in to anger, and was determined to make his goals a reality. While being merciless to his enemies, he was willing to defend civilians. His Teigu is Mastema - a pair of wings that allow him to fly and unleash piercing feathers to strike foes. Despite being mostly a ranged attacker, Run is proficient in hand to hand combat.
