Kamachi wrote a side story about it once actually. It was a parody one, and not canon, and it's never been translated (I've only ever read a summary). The joke was that it was volume #1000 (well some really high number anyways) and Touma had finally gotten to the point that he graduated. He had no idea what he wanted to do with himself but soon he was given job offers by Anti-Skill Necesarius, and others
