Gyutaro

Gyutaro was a tall man of fairly muscular build, with a pale gray complexion speckled with black blotches. His anatomy was quite strange in that his upper torso, arms, and legs were all defined with musculature, whereas his waist was incredibly skinny to the point of looking skeletal, with his pelvis jutting out at an unnatural angle. His spine was prominently visible through his back, and he was usually shown being hunched over. Gyutaro possessed thin, green and red eyes, their sclera bright yellow-orange, that were slanted drastically downwards at the sides, giving him a permanently haggard gaze. The kanji for "Upper Rank" (上じょう弦げん Jogen?) and daiji for "Six" (陸ろく Roku?) are carved across them. He had unruly black hair that transitioned to a brighter lime green around the crown of his head, worn messily in uneven bangs and several locks. His body and limbs had noticeable ink-like markings in the form of black spots on his body and a flowing water-like pattern on his face. He also had a full set of sharp, interlocking teeth. Gyutaro was described to look very ugly.Gyutaro wore little, only sporting a pair of baggy blue pants and seven pieces of pattern red cloth to decorate his body, one large one around his neck and three smaller ones around each arm.Gyutaro was cruel, ruthless, petty, and envious of anyone blessed with a better life than him, owing to a life of near-constant poverty and the harsh tragedies he experienced whilst human. He developed a habit of sarcastically complimenting a person's best traits before vindictively killing them afterwards, as he did to the samurai who attempted to kill him and Tengen Uzui after seeing his appearance. Because of the hardships he faced as a human, Gyutaro attained a personal belief that to take from those who have a better life than he had as a human was justified. A habit that developed from this belief was the penchant to inflict harm to himself whenever he was angry, frustrated or jealous, as seen when he scratched himself hard enough to tear deep wounds into his own flesh when he grew jealous of Tengen.Having lived over a hundred years and battled many Demon Slayers and Hashira, Gyutaro became arrogant and prideful in combat, developing the habit of underestimating his opponents and looking down on them as beneath him, as he did with the team of Demon Slayers dispatched to kill him by having his sister fight and deal with them first rather than himself. He has also showed himself to be intensely sadistic, revelling in the defeat of the Demon Slayers by horrifically injuring them and tormenting the helpless Tanjiro for his own enjoyment.Despite his negative traits, Gyutaro possessed a genuine, strong love for his younger sister, Ume. Having raised her himself due to his mother's mental instability and later death, this familial love was so strong that, even after becoming a demon and nearly forgetting his life as a human, he still retained a considerable attachment to her. Due to this, he occasionally spoilt and allowed her to do whatever she pleases, even if her actions went against his best interests. Raspy crooked voice. very protective of his baby sister. Overall Abilities Gyutaro uses his Blood Demon Art after being beheaded Gyutaro nearly decimating the entirety of the Entertainment District using his Blood Demon Art.

As the true Upper Rank Six, Gyutaro was an extremely powerful demon with over a century's worth of combat experience under his belt, having killed and devoured 15 Hashira in the past.[8] His strength and his abilities were made evident when he was able to easily combat both Tengen Uzui, the Sound Hashira of the Demon Slayer Corps, and Tanjiro Kamado, a talented Demon Slayer who had fought Lower Rank demons in the past, at the same time and eventually overwhelm them in battle. Tanjiro also noted that Gyutaro was so powerful, his demonic scent numbed the back of his throat. Even when the battle turned in the favor of the Demon Slayers, Gyutaro and Daki quickly managed to take control of the situation and drive them into a corner.

Another testament to his power was the fact that despite being effectively defeated in battle, Gyutaro was still capable of severely injuring Tengen, Tanjiro, Zenitsu, and Inosuke and would have likely killed them all had it not been for Nezuko, who neutralized his final attack's poison with her Blood Demon Art. Even as a human, Gyutaro was a naturally talented fighter, as displayed by how he was able to kill an adult samurai in one strike without ever having received any combat training beforehand.

Tactical Intellect: Gyutaro displayed incredible tactical foresight and intelligence. He was able to use the information he gathered from Daki to coordinate their attacks against his opponents. Gyutaro was also able to use his Blood Demon Art tactically to create inescapable attacks.[9] After seeing Hinatsuru fire a barrage of kunai, Gyutaro correctly surmised that mounting an attack that would normally be easily mitigated by his regeneration had an underlying motive and chose to deflect the attack rather than taking it head on.[10] He was also shown to use his flesh manipulation ability in creative ways, such as trapping Tengen's and Tanjiro's blade in his flesh Kama to keep them from moving.[11] Lastly, albeit post-facto, Gyutaro figured out Tanjiro's strategy which was to disguise the scent of the wisteria-laced kunai with a prostitute's incense bag in order to land a surprise attack on him.[12]

Demon Abilities Core Detachment: Gyutaro possessed the ability to completely detach his "core" from his own body, with it seemingly taking the form of his right eye that he then implants into his sister Daki's forehead, that then enhances and strengthens all of his sister's abilities and powers.[13] Through this, Gyutaro also developed a psychic connection with her, which allowed him to see, hear and sense everything she does and even possess and take control of her body in order to better coordinate their attacks.[14]

Decapitation Immunity: Additionally, through detaching his "core" from his body, Gyutaro was immune to death by decapitation by Nichirin Swords. This effectively ensured that both he and his sister could not be killed unless both of their heads are cut off simultaneously.[15] Extrasensory Perception: Through his psychic connection with Daki, Gyutaro could sense everything around her as well, allowing them to coordinate their attacks. This was shown when Gyutaro acted on the information given to him on pure instinct and maneuver both his and her attacks and actions perfectly while in battle, as seen during their battle against Tengen, Tanjiro, Inosuke and Zenitsu, where he perfectly coordinated his attacks with Daki's to both launch several simultaneous assaults on all four opponents despite the both of them fighting in separate locations and facing two entirely different pairs of opponents by manipulating his sister's actions and controlling her sashes to strike in tandem with his blood slashes to create powerful surprise attack combos.[16][17][18] Shared Biology: Gyutaro and Daki possessed a rather abnormal trait not seen in most demons. Despite the fact the siblings are two different people, the two had essentially a single body. This could be seen with how Gyutaro normally remained concealed within Daki without altering her physical mass in the slightest. Even though Gyutaro was inactive for the majority of the time, he was still more powerful than his sister who was an active predator. This implies that humans consumed by Daki also serve as nutrition for Gyutaro and vice versa, allowing the two to grow stronger at the same time. Gyutaro also has some control over his sister, being capable of not only reattaching her head for her, but also healing her burnt skin for her when she was under emotional distress. However, any damage one sibling takes is not reflected on the other.Flesh Manipulation: Like all demons, Gyutaro possessed the ability to manipulate his own flesh to a certain extent. He mainly used this ability to shape his flesh into a pair of extremely sharp Kamas which he could even control telekinetically.[19] This was also evident as Gyutaro could merge his body with Daki's and later managed to encroach and infect the swords of Tengen and Tanjiro with his flesh Kamas in order to prevent them from pulling out their blades, effectively keeping them in place. He also displayed the ability to twist his neck backwards.[20]Immense Regeneration: As a member of the Upper Ranks, Gyutaro's regenerative powers were extremely potent. With his immense recovery speed, he could instantly heal the scratches he inflicted upon himself in a matter of seconds.[21] More impressively, he could regenerate from the damages dealt to him by Tengen's explosive beads that possess enough explosive force to harm the body of even Daki.[22] Even when he was hit with Kunai that were coated with wisteria extract that could paralyze an ordinary demon for half a day and seal the movements of Lower Rank demons, upon removing them, Gyutaro still managed to regenerate nearly instantly afterwards.[23]

Poison Generation: Gyutaro possessed the ability to generate extremely lethal poison, which he uses to coat his blood sickles.[24] The poison was strong enough that it often kills someone inflicted with it within a few minutes, and those who don't will be severely weakened and will be rendered unable to fight. Even Tengen, who has developed a high tolerance to poison from his Shinobi training, was greatly weakened by Gyutaro's poison to the point he had to forcefully stop his heart to prevent it from spreading even further.[25] The poison had much worse effects on Tanjiro and Inosuke, despite the latter having a form of natural poison resistance.[26][27] Tanjiro was almost immediately incapacitated when he was inflicted by Gyutaro's poison just moments after getting stabbed while Inosuke was left in a near-death state after a while.[28] Physical Abilities Immense Durability: Gyutaro possessed an incredibly durable body, shown when Tengen and Tanjiro both used their Nichirin Swords to attack Gyutaro's Kamas made from his own flesh to no avail as they couldn't even slice through it.[11] When Tanjiro landed a surprise attack on Gyutaro's neck, his blade failed to make a dent in the Upper Rank's flesh.[29] Tanjiro was only able to slice through Gyutaro's neck when his Demon Slayer Mark was manifested in that moment, which amplified his strength greatly.[30]Immense Speed & Reflexes: As an Upper Rank demon, Gyutaro assimilated an extremely high concentration of Muzan Kibutsuji's blood which greatly enhanced his own speed and reflexes to levels that could out-match the Hashira. As seen with most demons, Gyutaro could also use bursts of speed so fast he appears to teleport.[31] He could also keep up with the blistering movements Tengen, the Hashira with the fastest running speed out of all his peers, sometimes moving fast enough to evade his reflexes and land hits on him before he could even react.[32][33] Gyutaro was also fast enough to block a barrage of fast-moving kunai.[34]

Immense Strength: Gyutaro possessed incredible physical strength, being able to clash head-on with Tengen Uzui, a Hashira who himself possessed a very large and muscular build. He was also able to break two of Tanjiro's fingers without effort,[35] send him flying into a building at high speeds, and cause Tanjiro to cough up blood with a single kick to the stomach. Gyutaro was also able to send Tengen flying back a great distance with another kick.[36]

Unlimited Stamina & Endurance: Like all demons, Gyutaro possessed an infinite amount of stamina and endurance. He was able to engage in combat with both Tengen and Tanjiro for the entire duration of the battle without showing any signs of fatigue or exertion. Gyutaro also possessed immense resilience to pain, shown when he scratched himself in anger hard enough to cause deep gouges, twisted his own neck backwards to block Tengen's sword attack, had both his legs sliced off, and when Tanjiro headbutted him square in the face.[37][38] Even before becoming a demon, when Gyutaro was slashed in the back by a katana, he still retained enough strength and stamina to retaliate against his would-be killer, and carry Ume's body all throughout their district to find help.[39]Kama Proficiency: Gyutaro displayed mastery in dual wielding his flesh Kama in combat. As an Upper Rank demon, he lived for over a century and has refined his skill to the point he can surpass the Hashira, the strongest swordsmen in the Demon Slayer Corps, in close ranged combat. Even before he became a demon, Gyutaro has shown to be apt in utilizing his Kama for violence, easily killing a woman and later slicing an adult swordsman's head in two with them when he was enraged. With his demon abilities, he could even control and move his flesh Kama telekinetically, which Gyutaro used to make them fly back to him like a boomerang.[19] As noted by Tengen and Inosuke, Gyutaro's fighting style was comparable to that of a praying mantis.[40][41] Gyutaro's combat style seemed to revolve around aiming to piercing his opponent's neck with the tip of his Kama.Blood Demon ArtBlood Manipulation: Gyutaro's Blood Demon Art allowed him to manipulate his own body's blood in various ways. He was shown to generate them from his flesh Kama or from open wounds on his body or release blood at will from his veins.[42][43] It was implied that Gyutaro doesn't run out of blood due to his regenerative abilities, giving him a virtually infinite source of blood to fuel his techniques. In combat, he usually created barrages of solidified sickle-shaped blood as sharp as blades that can travel at immensely fast speeds to attack his opponents. Gyutaro was capable of freely manipulating these blood slashes at will, altering their movements until they hit his opponent[15] or shaping them however he pleased. Furthermore, his blood sickles were coated in deadly poison.

Gyutaro could use his Blood Demon Art tactically to create inescapable attacks that can overwhelm Tengen[9] and hold off the combined efforts of Tanjiro, Zenitsu, and Inosuke. Moreover, the poison in Gyutaro's blood slashes appeared to be extremely deadly as Inosuke noted that a single scratch from them would be enough to kill him.[44] The blood he manipulated was shown to be quite durable as well since Tanjiro deduced that his sword would shatter if he took the technique head on without deflecting it.[45] Furthermore, Gyutaro could create a shield of blood in the form of a dome, which he used to protect himself from a barrage of kunai, further exemplifying its immense durability.[46] More impressively, Gyutaro can create long-ranged circular torrents of razor sharp blood that can decimate the surroundings with ease without moving his arms.[43] TechniquesFlying Blood Sickles (飛とび血ち鎌がま Tobi Chigama?)[42] - Gyutaro releases multiple sharp and durable sickle-shaped blades of solidified blood by swinging his Kama. He is also able to control these sickles at will. Rampant Arc Rampage (跋ばっ弧こ跳ちょう梁りょう Bakko Chōryō?)[47] - Gyutaro creates a dome of sickle-shaped blades of solidified blood around him that defend from incoming attacks. Rotating Circular Slashes: Flying Blood Sickles (円えん斬ざん旋せん廻かい・飛とび血ち鎌がま Enzan Senkai - Tobi Chigama?)[43] - Gyutaro unleashes circular waves of sharp solidified blood from his body. This technique has massive range and he is even able to activate it as his head is being cut off.Blood Sickle Onslaught (血ち鎌がま乱らん撃げき Chigama Rangeki?)[48] - Gyutaro unleashes a wild flurry of blood slashes in a similar fashion as Rampant Arc Rampage before finishing it off with an X-shaped cut. Blood Sickle Slash (血ち鎌がま斬ぎり Chigama Giri?)[48] - Gyutaro unleashes two downward slashes followed up with an upward strike right after. Flying Blood Sickles, Bend (飛とび血ち鎌がま・曲きよく Tobi Chigama - Kyoku?)[48] - Gyutaro rapidly swings his Kamas to generate enough momentum to perform a cross-slash, launching a large, X-shaped projectile of solidified blood. Rotating Circular Slashes, Flying Blood Sickles, Reap (円えん斬ざん旋せん廻かい・飛とび血ち鎌がま　斬ざん刈がい Enzan Senkai - Tobi Chigama - Zangai?)[48] - Gyutaro throws his Kamas towards his opponent and catches it from behind while mid-air, before releasing a series of slashes followed up with an upward strike that launches them skyward. Then he unleashes Rotating Circular Slashes, Flying Blood Sickles into the air, creating two tornadoes of solidified blood slashes flying towards the target and devours them at both directions. Equipment Flesh Kama: Gyutaro carried around a pair of Kama fashioned from his own flesh and blood, as such they are drenched with his poisonous blood.[49] They served as his main tools in combat and are extremely durable and sharp, being able to easily cut through flesh and block attacks from Nichirin Swords with ease. They had a fleshy exterior and were blood red in color. Gyutaro briefly displayed the ability to move his Kama telekinetically, making it fly back towards him as if it were a boomerang.[19] When he was a child, Gyutaro possessed a similar-looking Kama which someone left behind and was most likely his main source of inspiration for using a pair of Kama as a demon.[50]
