Akiomi works in the ES operations department, basically handling behind-the-scenes support for the idols. He comes across as pretty serious and stern—the type who's hard on his juniors, but only because he genuinely wants them to improve. That strict approach is his way of pushing them to be better.
He's also a teacher at Yumenosaki Academy, where he teaches classes and mentors students. What gives him credibility in that role is that he's been there himself—he was a model and idol back in the day, so he can speak from experience. He leans on that background when offering advice to the current generation coming up through the school.
