A husband's learning speed is unfathomable!
Kyoya did his best to not show any signs that might expose him.
He was aware that someone was spying on him thanks to his divine energy, but Kyoya had no means of finding the spy and was rather amateur when it came to this aspect.
His steps were unhalted and it was the most that Kyoya could do.
However, Kyoya has been spending some time with the assassin while looking at his moves deeply. The technique to hide his presence was something that piqued Kyoya's interest ever since the first day, so Kyoya was sometimes trying to reproduce it through his game system and The Assassin Craft.
From what he perceived, this was just one of the concepts that belonged to the movement technique of The Assassin Craft.
It was foreign subject for Kyoya, but he once felt he might of the movement technique thanks to his system and wife. It felt nice to jump around with special ability behind it as it not only relied on the speed.
