Yami Sukehiro

Yami is a tall, muscular man. He has black eyes and medium-length hair, which is messily combed back. He also has a stubble mustache and beard.

Yami's outfit is very simple and consists of only a white t-shirt and black pants. The pants have an extra layer of brown leather that covers his outer thighs down to his knees. The pants are held up by a belt around his waist. Yami wears another pair of belts, one of which he uses to carry his grimoire. Lastly, he wears tall black boots that cover most of his calves.

As the captain of the Black Bull Squad, Yami wears a black cape with his insignia on it. He wears it over his right shoulder and is attached by two ropes to his left shoulder. The cape also has frayed edges, which appear to have been torn off of a larger cape.

Yami is normally a very calm person of few words. However, he is quite irritable, being able to easily become enraged by something as simple as being hit by another person. Yami also has a tendency towards intimidation either with words or by physically harming his target. He tends to use force in the face of any problem or confrontation, such as when he destroys a part of the squad's headquarters to calm down his subordinates.

In addition, he also likes to instill tough love in his subordinates by giving them dangerous missions. He believes that it is the best way for them to overcome their limits and become stronger. Yami does not discriminate against people based on their social status or circumstances, which is why he accepts Luck Voltia, Noelle Silva, and Asta to join his ranks, despite being aware of each of their problems. From time to time, he goes gambling with Magna.
