Arthur did know of Jimte and Kalal's pride.
But when he saw Jimte and Kalal kneel on one knee, he realized he had still underestimated their pride.
Impossible! Impossible!
You two couldn't possibly think that I came here just for the two of you, right?
And to go through such an elaborate setup just for you two?
Arthur grumbled inwardly, but outwardly he remained calm.
It seemed as if he had anticipated everything.
Jimte and Kalal did not see it clearly, but they vaguely sensed—before the elevated Arthur, the two knelt on one knee, their heads bowed, right fists placed over their hearts.
"I, Jimte Norvia, hereby swear by 'my own name' and take my bloodline as my glory, to the person before me, Arthur Kredos, I vow to be loyal and fearless, to fight until death—glory is my life!"
