If there is one thing Kent is good at, then it is close combat, especially with a sword. He was the father of swordsmen, someone who mastered every possible move a swordsman could make.
Of course, one can argue and say he isn't his past self at the moment.
That is true; the current Kent is but a brat who has just started walking the path of a swordsman.
He had only recently reached the Sword Sage stage, which is several times far from reaching the peak of true swordsmanship.
So, using his past-life achievements to project his combat experience is more than shameless.
However, one thing can be said: the current him has mastered all 1.6 million sword moves a person could possibly think of. It took years for Jest to master all, and now Kent has all those moves.
So, despite being in a completely different universe, the same rules still apply, and Kent, who saw how dangerous Atria was, was using his talent in close combat to overwhelm her.
