I've dug him from the get-go! I liked the homage to the games with the first episode's theme, and I thought it was a clever way to initially separate itself from the same when it came time to reveal him. Seems more like they balanced him out, considering his character is now dealing with everyone... and not just three. I like Kenji Akabane's tone for the role, and it's nice I'm not much familiar with his other work as well. Awkward to say, but it still applies I suppose!
Doesn't feel strange to me that they simply call him "Producer" either, and I was afraid that would be the case. So far he's stuck to his role, even when delving into a friendly demeanor. He seems more like a mentor, with only the intent of supporting the other characters. At least, that's the vibe I get from his performance. A very swell performance at that, so it's all good.
I'll go in circles if I continue on, so I'll just say he's been a big thumbs up from episode #1 for me. He's not perfect, doesn't purport to be, and isn't afraid to admit mistakes. Even so he tries his best for the sake of everyone else (not just the "idols" themselves), yet takes an appropriate side-step when it's time for others to shine. Everyone seems to get an opportunity to further the story, and he's no exception.
