Such ugliness and unreality, the Empress of the Far North would react and evaluate it that way, considering her personality, perhaps this was the norm.
"Witches are such," Harls said, "My stance is to maintain order, and the witches disrupt it. If it were my true self here, not a phantom summoned by the Electronic Frontier, I should probably clash with her and then banish her."
Putting aside whether Harls had the power to do so, his attitude was definitely that he would act in this way, and at all costs.
"Unfortunately, with my current power, I'm afraid I can't do anything about her."
Even though Harls had the Flood as a power source, faced with a real witch, especially one who was becoming complete, even Harls was powerless: "It's just a pity for the beings active in this era. The witch has come, and they have no choice but to face calamity."
It's the same old story, Bailuo's happiness is derived from what the witch takes from others, built upon the pain of others.
