True nature

Zatiel and Ezequiel's flying speed reached an extraordinary level. It was like they were fusing their flying ability with some unique movement technique.

Not only did their speed reach an incredible level, but their presence also seemed to be hidden, as if they were in a different plane of existence. 

What became clear for everybody was the power of space-time that emerged from the duo's knees and seemed to be the origin of that ability.

Dean turned toward his brother, and there was an inquisitive light in his eyes. When it came to the Space-Time Laws, he knew that the Second Prince's comprehension should be the highest among those present.

Gabriel felt his brother's stare, and this entire time, his eyes had not left the duo that had already vanished in the distance.

"Their legs can touch the strings that represent the all-encompassing Space-Time Laws. They are literally moving along the flow of time."
