Continuity mistake: Ishizaki misses his tackle on Misugi and knocks down the supporters instead. You can see that they fall into the playing field, inside the lines. Sanae sits on him. Though and the lines are gone. The pants of the rightmost bystander go from brown to blue, also. (00:17:55)
Continuity mistake: Misugi's face during his careless last stride has a muddy look. One could think that he's turning blue because his heart is malfunctioning, and he's lacking oxygen. When Takasugi gives chase, he has a muddy face too in a shot as well. They are both clean later.
Continuity mistake: Takasugi's eyes as he cheers his team up are drawn in a way different from any other episode (as in, they are open!). Moreover, his elbow is still visible at the edge of the frame when the camera moves to Ishizaki, so he kept the same awkward position for an inane amount of time for no reason. (00:06:25)
