This is going to turn into one of those discussions right, like Ayu's lipsyncing or plastic surgeries, there's no answer to it. XD
It's true though, she's been using him way more and way longer than she used Naoto (or Mitsu, or Hide, etc.) She's just looking for someone who can stand out of the crowd (with her), and in this case it's only him and Maro. As much as you like the other dancers, you gotta admit, they don't stand out as much as these two do.
If that's not the case, I'm just gonna expect a TA message with a very special announcement then.
