Khal's palm was descending from above with crazy speed, ready to touch and manipulate the blood inside Logan's body.
However, even though knowing the imminent and unknown threat, Logan remained calm and slightly push to the side of his feet, he appeared behind Khal, his sword already targeting Khal's neck!
"Amazing! He not only copied Khal's movement technique perfectly but even cornered him with almost no effort at all! That's Logan for you!" Raffin exclaimed with admiration the moment Logan moved, completely oblivious by the fact Logan didn't copy but simply learned the Secret Art together with Khal.
As they were fixing and modifying the Art to become useable since the moment Khal acquired it, it was the norm for Logan to know how to utilize it.
