It is quite the bold move from Ryumon because he was in a situation where he had to buy time. The Empty Fort Stratagem, used in a way, showed the respect that he had for his opponent. Essentially he would have thought they would know about this strategy. Actually knowing the strategy adds to the wild card of what Ryuomon is really going for. Reverse psychology at work.
This moment shows the conviction that Ryumon has that Wajima lacks. Even if it is 1 extra second, Ryumon’s goal was to buy any amount of time; losing his life was something he came to terms with. While for Wajima he has been giving empty promises and tolerating the rape and murder of her men against the women who support her. It indicates that she lacks the conviction that those men will truly stand by her, so when she has to make a move against Ryumon, clearly her fear wins her over of not wanting to make a mistake.
Now the ball is in Asumi’s court; I’m curious what he goes with next.
