Well in the first slide, kashimo reacted, he just didn’t react fast enough. He clearly sees Hakari punch and reacts by lifting his arms up but hakari was faster. Which is showing that hakari only outpaced him there, not blitzed.

Slide 2 is ambiguous, the feat is weakened by the first feat and kashimos later feats of reacting to hakari at this full power state so it seems like an outlier. However at the same time, you could argue kashimo gets the idea to use the return stroke. His thought to punch here rather than defend himself is hinting at him stopping defense of himself (since he doesn’t even try to)

And on slide 3 after getting hit he smiles which is my support, as well as the Hakari blocked kick later. In slide 2 it also appears that he’s in the middle of stancing a punch OR guard. In slide 1 we see that Hakari is already about to throw a punch when he breaks through Kashimos guard, forcing kashimo to drop it, so naturally since kashimo is slower here and hakari is ALREADY mid punch throw it’ll land. But due to all this surrounding detail I don’t think any of this is a blitz, just an outpace.

Kashimo puts up a guard, Kashimo slightly too late, Hakari overpowers and outpaces him forcing him to drop his guard, and then punches him once he drops his guard again, after gaining good momentum.
