Ariyoshi was on a recent ep of the Shabekuri 007's 2.5hr SP (120326).
He said how great it was to do shows with AKB48. Because the viewers are all just AKB fans.
When checking Twitter, there's 0 comments about him. Everything he says, even if he's bad-mouthing the members on the show, doesn't really matter because it's like the viewers can't see/hear him.
He just feels like the invisible man and can freely do anything he wants.
