After the labyrinth in which the cheating opponent ended up giving Usogui what he wanted (relinquishing his loss to the leader), I'd loved to have seen Kaji not bring up that he was cheating, and instead quietly fuck his cheat up and watch him squirm when he realizes he can't accurately count time anymore and it becomes a true contest of time keeping.
Here's to hoping that it's simply a method that can't be stopped quietly, and that it must be brought to the surface to be addressed.
