A single punch, only one punch was used!
As agreed before the fight, Casio let Krogg have three moves. And then, at the very instant the third move ended, Casio delivered a counterpunch.
Butcher Krogg lost, overwhelmed by irrefutable, unostentatious strength. A direct and unambiguous defeat, the most devastating kind.
This revealed the vast gap between the two fighters.
At the edge of the dojo, Krogg heavily pressed his right hand onto the hilt of his pitch-dark slaughter knife. A sense of helplessness welled up within him, the realization that he had indeed aged. If he were still at his peak, the outcome would have been uncertain. He hesitated for a moment, suddenly realizing that he had inadvertently equated Casio's prowess to his own at his prime.
This was a subconscious recognition.
Simply put, Butcher Krogg was wholly convinced by a single punch.
Not far away, a tall figure was walking step by step towards the arena.
