It wasn't a one-sided battle with Kyoya dominating over the adventurers.
He had to exert as much strength as possible to keep considerable distance! It was mostly thanks to the Sagittarius Title that had brought three concepts with itself. One of these concepts was the speed that was further strengthened by the physique of the divine demon, Marisa.
The speed was Kyoya's strongest asset.
So even if the battle unfolded with Kyoya fighting during the day, his cards would still be hardly seen by the adventurers. They had to deepen their focus on Kyoya long-distance attacks which meant that more room was given for the husband!
Then, the concept of throwing polished Kyoya's style. His cards could've been thrown from any position, either while running or jumping.
