Well at least the author didn't disappoint. When it started a lot of people speculated that Yakou had a second handkerchief that would also be valid for the fight. It would have felt cheap to go that road.
Instead Yakou swapped it out with a normal one and outplayed Kadokura.
It seems like given how the fight was setup Yakou is going to win, not by a large margin, but it seems clear that Yakou is the author favorite to win this one.
I understand everyone wants Yakou to be the one to win, but also feel like Yakou is no longer suited to preside over the both of them due to his injuries.
In his first fight against Kadokura he couldn't do anything against him.
