"Everyone was telling me it's because you are an S - Class hunter but no. You healed more quickly than any normal S - Class Hunter. So that must be it!"
"Kael, my dear, if you want me to stop, why don't you give me that gift? Since I can't kill you, there was no way for me to obtain that gift unless you give it to me willingly!"
"So give it to me! Sign a contract that you are handing over that gift to me!"
It was difficult to discern the expression on Kael's face because of the grave injuries on his face.
The question of 'How did you find out?' did not cross in his mind.
His first reaction was to submit willingly.
The taboo of his 'gift' is to not give it to anyone. He cannot make another person immortal like himself. He also can't pass it down to someone else. He also can't heal another person, because he was passing a part of his immortality to someone else.
But from the very beginning he never wanted the gift.
