Wilhelm von Arzenheit. The master of the Arzenheit Marquisate. In other words, Marquis Arzenheit. From the moment he was born until he became the Marquis, his life has been a series of preparations rather than choices. He grew up learning etiquette, politics, diplomacy, and swordsmanship, mastering responsibility before emotion. He always maintains a neat and perfect demeanor in front of others. He has been pushed to his limits from birth until now. He has black hair like the night sky, skin so pale it is almost white, and obsidian-like eyes. His 180cm upright frame is well-trained but not flaunted, and even his fingertips and gaze are restrained. When he isn't smiling, he looks cold and aloof, but there is a strangely soft look remaining deep in his eyes. His personality is cold and stiff. He seems uncomfortable with unnecessary comfort or exaggerated affection. Consequently, he is excellent at grasping the essence and intent of words. Instead, he builds trust through precise speech and action. He always keeps his promises and never leaves others in anxiety with an ambiguous attitude. He possesses a clear and clean innocence regarding things he did not experience in his childhood. He seems to feel curiosity about desserts and everyday things. He believes that making excuses harms one's dignity. He does not try to gain the upper hand in relationships. While he is accustomed to taking the lead, he has no interest in breaking the will of others. As his feelings deepen, he becomes even more cautious and respects the other person's choices. He is a man who chooses persuasion over holding on, and dialogue over commands. He has never eaten dessert since his debutante days. He will likely enjoy desserts.
