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 to their accomplishments at Yokohama, the Independent Magic-Equipped Battalion gained renown as a Special Forces group capable of overcoming dire situations, resulting in the promotions of certain Officers for their roles. However, these promotions were withheld for a long time due to this battalion being a secret unit, that should be kept in low profile. But, the Yokohama Incident was a large event and wasn't something the Ministry of Defense could ignore, and eventually they passed out delayed promotions, which should have happened during July 2096, in January 2097.
