Hyo, hyo! What a childish provocation! Did you think I, Gyokko, would be undone with such prattle? You seem desperate. It's embarrassing.

Gyokko ( (ぎょ) (っこ) Gyokko?), along with Hantengu, was one of the primary antagonists in the Swordsmith Village Arc of Demon Slayer: Kimetsu no Yaiba. He was a demon affiliated with the Twelve Kizuki, holding the position of Upper Rank Five ( (じょう) (げん) () Jōgen no Go?).[2]

Before becoming a demon, he was a human by the name of Managi ( () () () Managi?).[1]


Gyokko had a very bizarre and grotesque physiology, taking on the size of a pale white, abstracted, grotesque humanoid figure with a muscular upper torso that has no arms and resembles that of an armless statue growing from a porcelain vase, similar to tát a djinn. He had multiple infant-like hands that line along his head and back.

Gyokko's face was even more distorted, with large green mouths located where one would expect his eyes to tát be located, and his actual eyes were located vertically from one another on his face; one eye appeared in the constantly open bottom mouth and the other was seated at the center of his forehead. The daiji for Upper Rank ( (じょう) (げん) Jōgen?) was engraved on his forehead's eye and the daiji for Five ( () Go?) was engraved on his mouth's eye.

When in battle, Gyokko was shown to tát molt and transform into his true size, which bore heavy resemblance to tát that of a merman. In this state, Gyokko retained his facial features and muscular physique but now possessed a more humanoid toàn thân covered in transparent scales akin to tát a fish. He also grew much larger, attains longer fish tail-like hair, Black markings on various places around his toàn thân, webbed hands, and a long serpent-like tail in place of his legs.



Gyokko enraptured by Muzan's hand on his head

Gyokko was shown to tát be an easily excitable demon, constantly fawning over new inspirations for what he deems his "art" or what he finds to tát be sublime, sometimes even going against his initial impressions. He was easily swayed into euphoria whenever Muzan was involved, trying not only to tát please him, but finding joy in being decapitated and having his head held by Muzan. Although he was dismayed he would have to tát work together with Hantengu, he nonetheless reasoned it was fine since Muzan ordered it. He also seemed to tát be somewhat sardonic and condescending; upon sensing Akaza's presence within the Infinity Castle, he almost let out his inner feelings to tát the demon about being glad he believed him to tát be dead before correcting himself mid-sentence, even if Akaza was not fooled by his false tư vấn.

Gyokko enraged at Muichiro's insult

Gyokko enraged at Muichiro's insults towards his vase.

Gyokko was also short-tempered, shallow, and arrogant, especially when it comes to tát things regarding his "art", as seen when he was easily enraged by Muichiro when the latter began to tát insult and make fun of the quality of his art to tát the point of bleeding from his blood vessels out of sheer fury, and through his conversation with the Hashira, constantly praised himself as "beautiful" and his work even more so sánh, further reinforcing his arrogant and narcissistic personality and even insulting Muichiro as an "ape" for not appreciating his art. His arrogance was most prominently displayed after he was beheaded by Muichiro Tokito, referring to tát the Mist Hashira as an inferior and lower life size while calling himself a superb and chosen being.[3]

Gyokko revealed himself to tát be incredibly petty and jealous, as seen when he attacked and mutilated Hotaru Haganezuka due to tát his jealousy of the latter's focus and dedication to tát his work, surpassing his own zeal when working on his own art and made him want to tát instead make the latter lose his focus and waste time on the swordsmith due to tát this petty jealousy.

Death Throes of the Smiths (Anime)

Gyokko's "creation", made up of mangled, still-living victims.

Gyokko had a particularly morbid sense of taste, which was showcased when Doma told him he placed a human head on top of his pots lượt thích a plant; although Gyokko was slightly taken aback since the pot was not made with such an intention in mind, he nonetheless approved of such use and decided to tát use it as further inspiration. The extent of this morbid and violent obsession for his was shown even more when he brutally attacked several swordsmiths and used their corpses to tát create a "beautiful" piece by mangling their bodies together along with sticking several swords into them.

His extreme sadism was further exposed when he went into great detail of explaining his "artwork"; from the many distorted toàn thân parts that stood out, to tát the built-in "feature" of being able to tát twist a stabbed sword in order to tát cause extreme pain and bleeding to tát one of the mangled swordsmiths, demonstrating he not only left his victims unnaturally alive, but also made arrangements to tát torture them in public.


Overall Abilities[]

As the holder of the fifth highest position in the Twelve Kizuki, Gyokko was an extremely powerful demon. His unique Blood Demon Art and techniques allow him to tát easily outclass the average demons and give him the necessary edge to tát overwhelm and kill even the Hashira, the most skilled and powerful swordsman in the Demon Slayer Corps. As Upper Rank Five, Gyokko is more powerful phàn nàn Gyutaro and Daki, the former having killed 15 Hashira and the latter having killed 7.[4] Gyokko has displayed many impressive feats of strength. Most notably, in his duel with Muichiro Tokito, Gyokko was able to tát overpower and hold the Hashira back for the majority of their fight, even managing to tát bring him to tát the brink of death. If not for Gyokko's inherent egotistical nature and Muichiro awakening his Demon Slayer Mark, the Upper Rank would have more phàn nàn likely been able to tát kill him.

Talented Artist: Due to tát his obsession with pots, Gyokko became very skilled at painting and making them, so sánh much so sánh that Muzan has taken a keen interest in them, even selling them for a high price, implying that they were made with amazing skill and craftsmanship.

Demon Abilities[]

Flesh Manipulation: Like all demons, Gyokko possessed the ability to tát manipulate his own flesh. He used this ability to tát shift his facial features and adopt his unusual djinn-like physiology. Gyokko also displayed the ability to tát grow numerous short arms on his head and torso, even while he was decapitated.[3] Additionally, Gyokko's numerous vases were made from his own flesh, as seen when he was able to tát instantly size them in his hand in order to tát use.

Immense Regeneration: As an Upper Rank demon, Gyokko had very powerful regeneration. This was shown when he survived being decapitated by Muzan Kibutsuji and later sealed off the wound and reattached his head.[5] He also displayed the ability to tát quickly heal injuries inflicted by Nichirin Swords without much difficulty.[6]Most astoundingly, Gyokko was shown being able to tát survive direct decapitation from a Nichirin sword, attempting to tát grow his toàn thân back from the stump of his neck, though Muichiro was able to tát overwhelm it by slicing him into countless small pieces, eventually killing him.[7]

Gyokko's fish transmutation ability

Molting Transformation: In dire situations, Gyokko could molt and transform into his true size, boosting all his abilities and liberates him from his vase, allowing him to tát move freely without needing to tát teleport.[8] Gyokko's true toàn thân was extremely durable as well, since the Upper Rank remarked that the scales that cover his toàn thân are harder phàn nàn diamond. Furthermore, whatever Gyokko touches was instantly transmuted into fish, which made him extremely dangerous to tát fight in close range.[9]

Physical Abilities[]

Immense Durability: As an Upper Rank, Gyokko possessed an extremely durable toàn thân superior to tát that of Gyutaro, whose neck was nigh-uncuttable to tát Tanjiro Kamado. A single slash from Muichiro could only somewhat penetrate his neck instead of cutting it off, although the Mist Hashira's sword was badly chipped and he also had not manifested his Demon Slayer Mark at the time.[10] His durability was further amplified in his molted size, where Gyokko's skin became layered in thick and hard scales that he noted to tát be harder phàn nàn diamond,[11] making his toàn thân extremely fortified.

Immense Speed & Reflexes: Gyokko was incredibly fast, as shown when he easily evaded Muichiro's attacks[12] and unleashed techniques that the Mist Hashira was barely able to tát dodge.[13] Furthermore, Gyokko managed to tát react to tát a surprise attack by Muichiro who had awakened his Demon Slayer Mark, which showed that his movement tốc độ would have amplified considerably.[14] Later on, Gyokko managed to tát hold off the marked Hashira for an extended period of time, even managing to tát move so sánh fast he appeared to tát teleport and overpower Muichiro briefly using his sheer tốc độ.[15][16]

Unlimited Stamina & Endurance: Like all demons, Gyokko possessed infinite stamina and endurance. He first displayed this when being decapitated by Muzan, where the Upper Rank didn't show any signs of pain, and even commented on how pleasurable it was.[5] Furthermore, Gyokko commented on how having a sword slash his neck was beautiful.[17]

Fighting Style[]

Blood Demon Art[]

Gyokko eating a swordsmith

Porcelain Vase Spells: Gyokko's Blood Demon Art revolved around his porcelain vases. He was able to tát spawn them anywhere within his vicinity and create multiple pots of varying sizes at once. Gyokko first displayed the ability to tát freely teleport from one pot to tát another instantaneously, offsetting his lack of legs and allowing him to tát travel far distances with minimal effort as well as to tát evade attacks easily.[18] Gyokko could also trap objects (such as people) inside his pots. If the object he wishes to tát seal is too big, the pots can simply compress them to tát fit inside.[19] The pots also seem to tát give Gyokko liberty of whatever was inside, which he uses to tát merge the swordsmiths together in impossible ways and allows him to tát create whatever he pleases inside them.

Gyokko's fish demons attack the village

Fish demons spawned by Gyokko.

During his attack on the Swordsmith Village, Gyokko spawned numerous gigantic fish-like amalgamations to tát terrorize the village and kill its inhabitants. They were unable to tát be killed by regular means and only die when the pots on their back are destroyed.[20] These creatures all possessed unique traits and characteristics, some had sharp claws,[21] some had multiple humanoid legs or even monstrous teeth.[22] They also seemed to tát be decently powerful, as these amalgamations were able to tát kill the Demon Slayers that were meant to tát guard to tát village.[23] However, their strength still paled in comparison to tát the Hashira, as Mitsuri and Muichiro swiftly subdued these spawn with ease.[24][25]

Gyokko attacks Kozo

Gyokko uses sharp water tendrils to tát cut his targets.

Gyokko's Blood Demon Art was notably themed around the sea and aquatic lifeforms, as his techniques were based on summoning non-sentient creatures that resembled fish from his pots. These fish monsters similarly possessed differing abilities and characteristics: some of them could shoot out a barrage of poisonous needles at his targets[26] or leave behind dangerous poison once they are killed.[27] He also summoned goldfish-like monsters with scythe-like appendages to tát threaten Hotaru Haganezuka.[28] Gyokko could also summon giant octopus tentacles from his vases to tát restrain his enemies or destroy the surroundings.[29] Lastly, Gyokko could also manipulate and create water from his porcelain vases, which he can use as a cannon-like attack in which he shoots out powerful streams of water or shape water into sharp, high-pressure tendrils to tát cut targets lượt thích a sharp whip or even suffocate his targets by trapping them inside an extremely durable vase made of water.[30]

  • Water Prison Pot ( (すい) (ごく) (ばち) Suigokubachi?)[30] - Gyokko creates a vase structure made out of water that traps the target. The water suffocates the target and prevents them from using any breathing technique, making it difficult for them to tát break không lấy phí and escape.[17]
  • Octopus Vase Hell ( (たこ) (つぼ) () (ごく) Takotsubo Jigoku?)[29] - Gyokko manifest gigantic tentacles from his pots to tát restrain his targets. These tentacles are strong enough to tát destroy a shed and are noted to tát be extremely durable.[32]
  • Ten Thousand Gliding Slime-Fish ( (いち) (まん) (かっ) (くう) (ねん) (ぎょ) Ichiman Kakkūnengyo?)[27] - Gyokko summons a total of ten thousand slime-fish from multiple pots to tát attack his target and devour them whole, leaving nothing but bones. When these fish are cut, they release a poison before disintegrating completely. This poison is percutaneous, meaning it can merely be absorbed through the skin in order to tát kill a target.[33]
  • Killer Fish Scales ( (じん) (さつ) (ぎょ) (りん) Jinsatsu Gyorin?)[16] - In his true size, Gyokko delivers a wide-ranged barrage of physical attacks made all the more powerful by his immense tốc độ and unusual toàn thân constitution. Through his special scales, he is able to tát manipulate his direction and attack at odd angles, making his attacks wildly unpredictable.
