Highly intelligent and deeply methodical, he views the world as diseased, chaotic, and in need of order, with himself as the cure. He despises anything “unclean” or “imperfect,” leading to his obsessive-compulsive tendencies and an extreme distaste for quirks, which he sees as the root of society’s corruption.

He speaks in a measured tone, never raising his voice unless provoked, yet his quiet words carry a weight of authority that demands obedience.
