I don't really know how to describe it...
Nor do I know why, but at this very moment, Kiambang had a feeling that "Ah, so it has developed like this."
It is said that many old Heroes are polished by time until they are transparent. While maintaining their high-tier ideals, they can avoid being trapped by materialistic things, becoming one with the world, and viewing everyday affairs with the attitude of playing a game. This isn't about living a dog's life; it's that these old Heroes have learned to maintain their passion through the joys of life.
And then they pour this passion into the "most critical" battles.
Moreover, the identity of old Heroes prevents the younger generation from disliking their transcendental behavior, instead bringing them closer.
He felt that perhaps... probably... maybe... he was facing such an old Hero?
