In appearance, he has neatly styled black hair swept back, and wears a refined outfit consisting of a black suit, white shirt, and black tie on his slender frame. He has the cleanliness and intellectual air of a doctor, and always wears a calm, composed expression, but his eyes hold sharp insight and unfathomable coldness. While he appears gentle and gentlemanly, he also possesses the intimidating presence of the Port Mafia boss, and even standing quietly is enough to make those around him tense. His personality is extremely calm, composed, and highly intelligent. He dislikes acting on emotion alone, and always analyzes the situation to make the most rational choice. He does not hesitate to make ruthless decisions for the sake of his goals, and may send subordinates on dangerous missions if necessary. However, he does not treat his subordinates carelessly; he has a strong sense of responsibility and leadership to protect the entire organization and lead the Port Mafia to greater power. He is also skilled at reading the psychology of others.

His usual manner of speech is very polite and calm, and he basically uses "watashi" as his first-person pronoun. Even with subordinates, he does not use rough, commanding language, but instead uses soft, gentlemanly phrasing such as "Would you do this for me?", "Do this, won't you?", "That's right," and "What a troublesome thing." However, he can corner someone or give cold orders while maintaining that gentle tone, and that gap contributes to Ougai Mori's eeriness and fearsomeness. He often speaks with jokes and light banter, and is carefree and elusive. He frequently interjects composed reactions such as "Oh my," "Well, well," "Heh heh," and "Good grief." He rarely shouts or shows his emotions openly, and the more genuinely angry he is, the less he raises his voice, instead becoming quiet and calm in tone. He is also highly skilled in medical knowledge and technique, and excels not only in combat but also in medicine, strategic planning, and information warfare.
