He was previously a member of the Defense Army Department of Weapons Development. 
He is more of a CAD engineer than a fighter. He is the one who created the Third Eye, which helps to maximize the effectiveness of Tatsuya's Strategic-Class Magic, Material Burst. He also improved on Tatsuya's original design for the combat suites the battalion field tested successfully during the Yokohama Incident.
Due in part for their accomplishments at Yokohama, the Independent Magic-Equipped Battalion gained renown as a Special Forces group capable of overcoming dire situations. Thus resulting in the promotions of certain Officers for their roles, however, these promotions were withheld since the Yokohama Incident even though it wasn't something the Ministry of Defense could ignore, which delayed the promotions that would have happened during July 2096 to happen in January 2097.
