It is said that antelopes can sense the approach of danger in advance.
Kieren is not an antelope, but he clearly has a similar ability.
After Redio uttered that prophecy known to everyone throughout history in front of Solomon, Kieren's heart sensed a strong feeling of impending doom.
He couldn't believe that this young Sabbath, who appeared a bit gloomy and had a sharp smile, was truly world-weary and thought he had lived enough, and actually went to provoke this Wing Tribe Commander, Solomon.
If he had known about this, Kieren would have stopped him at all costs.
But it's too late to talk about it now, even though Kieren had long sworn to Solomon that he no longer had any ties to the Double Rest Sect, it was Redio who suddenly sought him out, asking him for a small favor in the name of past relations, to arrange this meeting.
