A former member of the Phantom Triggers, the organization that evolved into SORD, who doubled as the team's instructor and handler. His main job was to teach his students the skills they needed to prevent them from being killed in action. While he's normally a calm and collected thinker, it is rumored that he's seriously scary on the battlefield. He never bragged about his accomplishments on the field, though he could be quite talkative when he was off the clock. As the only responsible adult on the team, he is the only father figure that Haruto has ever had. "Aoi-kun, this isn't a game. Get a move on and wrap things up. There's no need to go all out on a simple job like this."
