Sekido
Cuddling with Sekido.
Sekido is a tall young adult man with a lean muscular build and long wavy hair that goes past his shoulders and narrow, deep red eyes that have the daiji of "Upper Rank" and "Four" engraved into them. He has two prominent curved horns on his forehead and markings under his eyes that give his face a cracked appearance. He also has the kanji for "anger" etched into his tongue. As a demon, Sekido has pointed ears and sharp nails on each finger. He is usually seen wearing an irritated or enraged expression on his face.
Sekido wears the same kimono as Hantengu, as he is formed from Hantengu's headless body. He also wears dark hakama pants and a pair of zลri. Sekido is always seen carrying around a Khakkhara.
As the manifestation of Hantengu's anger, Sekido was in a constant state of vexation, irritation, and rage, even towards his fellow clones, which could be seen when he easily got angered when they failed to meet his expectations and were subdued by the Demon Slayers. Sekido was also seen to care very little about his brethren, as shown when he forcibly absorbed them against their will to form Zohakuten, even as Aizetsu protested. He also showed himself to be the most dominant of the emotion clones and appeared to be the leader, as he was the one who gave out orders to them and took charge at critical junctures when they were battling the Demon Slayers.
Demon Abilities
Biological Absorption: Sekido displayed the ability to draw in and absorb the bodies of Karaku, Urogi, and Aizetsu, fusing to become Zohakuten.
Flesh Manipulation: Like all demons, Sekido possesses the ability to control and alter his flesh to a certain extent. Sekido uses this ability to shape his flesh into a Khakkhara which he uses as a means to channel his Blood Demon Art. He is shown to be capable of creating more than one at a time.
Physical Abilities
Immense Speed & Reflexes: As an Upper Rank demon, Sekido possesses incredible speed and reflexes comparable to that of the Hashira. This was shown when he was fast enough to block the bullets from Genya's shotgun before they could reach him. He is also seen being able to absorb Karaku, Urogi, and Aizetsu in the mere blink of an eye to transform into Zohakuten, a feat only witnessed by the perception of the demon-enhanced Genya.
Electricity Generation: Sekido's Blood Demon Art allows him to generate electricity that flashes blue and red from his Khakkhara by stabbing it onto a surface, typically the ground. His electricity is extremely potent, instantly paralyzing targets, even if they are in mid-air, and causing them to lose consciousness in a short period of time. His Blood Demon Art has a wide area of effect, allowing him to subdue multiple targets at once. He can also summon electricity in the form of lightning that strikes his targets from above. One drawback to his electricity is that it cannot pass through anything made from his own cells, such as the body parts of any of Hantengu's clones, which Tanjiro utilized to avoid getting shocked.
Khakkhara: Sekido wields a Khakkhara fashioned from his flesh. It serves as his main tool in combat when used in conjunction with his Blood Demon Art, allowing him to channel his lightning and strike at close and wide ranges to shock, paralyze, and incapacitate his targets. Sekido has also been shown to create multiple Khakkharas at the same time, as he formed a new one in his hand to attack Tanjiro whilst his previous one was still imbedded in Nezuko's neck.
