Yami Sukehiro

Yami Sukehiro is a foreigner from the Hino Country and the first captain of the Clover Kingdom's Black Bull squad of the Magic Knights. He is also a former member of the Grey Deer squad. Yami uses this rare magic attribute to generate and manipulate the element of darkness. He primarily uses this magic by channeling it into his katana. This magic has the ability to draw in other forms of magic, namely Light Magic, absorbing it into the darkness and can even affect the other world. Due to his Dark Magic's ability to affect the other world naturally, Yami is ranked as an Arcane Stage mage. Yami uses this form of magic to increase his physical abilities. It also allows him to make up for the slow speed of his Dark Magic. His skill is great enough to remain standing under the immense pressure of Dante Zogratis's devil-boosted Gravity Magic. Yami uses this form of magic to restrain his opponents with darkness. Yami combines his Dark Magic with Nacht Faust's Shadow Magic. Dark and Shadow go very well together, and continuously synergize and strengthen each other. Yami has described himself as a magic swordsman. He is extremely skilled in swordsmanship; he easily fights on par with Patolli, the leader of the Eye of the Midnight Sun, with nothing but swordplay in conjunction with his Dark Magic, destroying the surrounding environment.

Yami naturally possesses tremendous physical strength which he further increases with magic. He easily throws Asta a considerable distance with just one hand. Using ki, Yami can predict and react to attacks that others cannot keep up with and nonchalantly counters these attacks without having to turn around. By combining Mana Zone with Ki-sensing, Yami can react to his opponents' movements before they make them, similar to Julius's future-seeing ability, though he states that it is not on Julius's level. Yami is an extremely durable fighter, remaining unfazed when hit by Patolli's light blades, and emerges completely unscathed at his attempted cave in. His amount of durability let him still attack and remain standing after being hit by a huge pillar of stone created by Dante Zogratis. Yami is extremely fast, able to keep up with and surprise someone as fast as Patolli with his speed. When Lotus Whomalt attempts to launch a surprise attack on William Vangeance, despite having to climb a massive tree, Yami arrives just in time to intercept him. He is also capable of dodging Marx's elf-enhanced arrows that are faster than normal. His enhanced reflexes from Mana Zone and Ki-sensing, as well as the power boost from Mana Zone, allow Yami to dodge devil-enhanced attacks for a short time. As a captain of a Magic Knights squad, Yami possesses an immense amount of magic power, which is greater than all commoners and nobles, with only very powerful Clover royals, the strongest of elves, and high-ranking devils surpassing him in this regard. Anti-birds flee as soon as they realize his presence, and the slightest release of his power intimidates multiple people. After Yami blocks and counters Patolli, Valtos wonders if the captain could rival the Magic Emperor. Gifso, the High Priest of the Seabed Temple, acknowledges Yami as being too powerful for his game. When watching his squad fight to the brink of death, he surpasses his limits to escape Abari's Different Dimension Sphere and becomes powerful enough to easily defeat Vetto. Julius Novachrono states that Yami has grown more powerful after he returns to the kingdom. During the Qliphoth Advent Ritual, Yami's body is altered, which Grey compares to Asta's devil-possession. Because of this, his body is overflowing with magic power. A principle originating from his homeland, this skill allows Yami to use a sixth sense to perceive and react to unseen attacks and persons. Yami can control all the mana in an area around him to increase his spells' power and range, and to stand and maneuver in midair. Yami possesses a three-leaf clover grimoire that contains various darkness-based spells. In combat, Yami uses a katana, a type of sword from his homeland, the Hino Country. As such, he has to have the sword custom-made. It is broken by Vetto during their first encounter but replaced with a brand new one afterwards. During their fight with Dante, Yami lends his katana to Asta, and he coats it in Anti Magic. Afterward, the sword is stored in Asta's grimoire. Yami possesses a small device that allows him to communicate with the members of his squad. It can only transmit audio. A wooden sword created by William Vangeance, it is filled with World Tree Magic. Yami wields it in the fight against Lucifero. 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 who was able to recognize Asta's merits when none of the other Captains would give him a chance. 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. Despite being very bull-headed, reckless, and unrefined, Yami is an experienced and perceptive warrior, picking apart his opponent's strategies with a glance and is constantly trying to come up with counters for them. Furthermore, he also prefers instilling tough love to his subordinates by giving them dangerous missions. He believes that it is the best way for them to overcome their limits and grow stronger. Yami also does not discriminate people according to their social status or circumstances where he is willing to accept Luck Voltia, Noelle Silva, and Asta to join his ranks, even though he is aware of each of their problems. His concern for them is likely tied to his own circumstances, being treated as an outcast in his youth like they are.
