Exactly, his gimmick is over and part of his gimmick that resonates with Japanese audiences is that he's raging against a perceived glass ceiling in his workplace. He comes to the ring in a suit like every Satoshi Salaryman who came to the show straight from his hard ass job, sheds it and starts spitting on people. That speaks to them.
they always say when it comes to booking that the money is in the chase, and being so over he's basically a crown-less people's champ. IMO The rebel loses some of his rebellious luster when he already has the top prize. Not even necessarily saying I agree with it just that I can see the logic.
