Yami Sukehiro

Yami is a tall man with a very muscular build. He has grey eyes and black hair of medium length that is messily combed backward, making it stick outwards. Additionally, he sports a stubble mustache and beard.

Yami's attire is very simple and consists only of a white A-shirt and black trousers. The trousers have an extra layer of tan leather that covers his outer thighs and down to his knees. The trousers are only supported by a belt around his waist. Yami wears another pair of belts, one of which he uses to carry his grimoire. Lastly, he wears black high boots that cover most of his calves.

As the captain of the Black Bull squad, Yami wears a black banner with the squad's insignia on it. He wears it over his right shoulder and it is attached by two strings to his left shoulder.

Yami is uncouth, reckless, slightly hypocritical, and prone to delivering death threats at the slightest provocation. Nevertheless, he is a powerful and well-respected Magic Knight.

He is typically a stoic man who believes more in actions than in words. He is very hot-headed, who can be easily angered by small matters such as being bumped by another person or interrupted when talking. Yami also has a penchant for intimidation whether he uses threatening words or physically harms his target. He also tends to immediately go straight for a more physical solution to any problems or confrontations, such as when he destroys a part of the squad's headquarters to calm his subordinates.
