Gyokko

A decapitated Gyokko's enjoyment in being held by Muzan. Gyokko was shown to be an easily excitable demon, constantly fawning over new inspirations for what he deems his "art" or what he finds to be sublime, sometimes even going against his initial impressions. He was easily swayed into euphoria whenever Muzan Kibutsuji was involved, trying not only to please him, but finding joy in being decapitated and having his head held by Muzan. Although he was dismayed he would have to work together with Hantengu, he nonetheless reasoned it was fine since Muzan ordered it. He also seemed to be somewhat sardonic and condescending; upon sensing Akaza's presence within the Infinity Castle, he almost let out his inner feelings to the demon about being glad he believed him to be dead before correcting himself mid-sentence, even if Akaza was not fooled by his false support. thumb|200xGyokko enraged at Muichiro's insults towards his vase. Gyokko was also short-tempered, shallow, and arrogant, especially when it comes to things regarding his "art", as seen when he was easily enraged by Muichiro Tokito when the latter began to insult and make fun of the quality of his art to 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, 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, referring to the Mist Hashira as an inferior and lower life form while calling himself a superb and chosen being. Gyokko revealed himself to be incredibly petty and jealous, as seen when he attacked and mutilated Hotaru Haganezuka due to his jealousy of the latter's focus and dedication to his work, surpassing his own zeal when working on his own art and made him want to instead make the latter lose his focus and waste time on the swordsmith due to this petty jealousy. While demons usually have a scornful view on humans, Gyokko's misanthropy was to the extreme. When Muichiro endured several poison needles from his Blood Demon Art to protect Kozo Kanamori and Kotetsu, he degraded their lives as "worthless" and mocked Muichiro for his decision. Moreover, when beheaded, Gyokko made an impassioned rant decrying Muichiro's inferiority as human and claiming that he had used his "godly hands" to turn the worthless lives of humans into art. Gyokko's "creation", made up of mangled, still-living victims. Gyokko was incredibly sadistic and had a particularly morbid sense of taste, which was showcased when Doma told him he placed a human head on top of his pots like 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 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 create a "beautiful" piece of art 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 body parts that stood out, to the built-in "feature" of being able to twist a stabbed sword in order to cause extreme pain and bleeding to one of the mangled swordsmiths, demonstrating he not only left his victims unnaturally alive, but that unlike other Upper Ranks, Gyokko liked to draw out his victims’ suffering. In addition, when first meeting Muichiro, Kozo, and Kotetsu, he presents himself as a chivalrous host presenting an art piece, but his his delighted expression when witnessing the villager's horror to "Death Throes of the Smiths" made it clear that his courteous behavior was a façade for his own amusement. As a human named Managi, his disturbed and violent mind was evident since childhood. His morbid sense of beauty and artwork was seen when he thought the corpses of his drowned parents were beautiful, and when he killed and skinned animals and fish to use for his art pieces. His fragile pride was demonstrated when the mere teasing of a village child enraged Managi enough for him to murder the child and stuff the corpse in a vase, the incident which caused him to be nearly lynched before turning into a demon by Muzan. thumb|Gyokko's uncharacteristic unease towards Doma's attempted insubordination. Despite his notorious depravity and arrogance, Gyokko could have occasional moments of rationality. He hesitated in allowing Doma to accompany him into the Swordsmith Village, knowing that it would be without Muzan's explicit permission, and was disturbed at Akaza lopping of Doma's head in retaliation. When Doma was distracted, Gyokko immediately ordered Nakime to teleport him to his destination bef...

Gyokko had a very bizarre and grotesque physiology, taking on the form of a pale white, abstracted, grotesque humanoid figure with a muscular upper torso that has no arms. His form resembles that of an armless statue growing from a white porcelain vase that is decorated with branch of green leaves and red, yellow, and dark green with purple leaves, similar to a djinn. His midsection is a red-violet color while his lower-half, or his tail is black. He had multiple underdeveloped and infant-like hands with red fingernails; four on his head that replaced his ears and were always present, and several lining up his body and tail which he can retract at will. He also possessed thin fins on the top and back of his head that were akin to hair, which were of a blended hue of purple and a blue-violet color and shaped in the style of cornrows and a ponytail. Gyokko's face was even more distorted, with large green-lipped mouths located where one would expect his eyes sockets to be located, which always displayed his hyperrealistic teeth and sometimes had one of or both of his tongues sticking out, along with a sharp nose. His actual eyes were located vertically from one another on his face; one eye, golden yellow iris with a honey brown center and visible veins, appeared in the constantly open bottom mouth and the other, similarly golden yellow eye with a honey brown center and visible veins, was seated at the center of his forehead. Three brown dots were on top of the latter eye. The kanji for |Jōgen}} was engraved on his forehead's eye and the daiji for |Go}} was engraved on his mouth's eye. In addition, his twin green mouths are generally expressionless and only move when speaking or eating, while the mouth that displays his lower eye is the one that contorts to display Gyokko's emotions. When in battle, Gyokko was shown to molt and transform into his true form, which bore heavy resemblance to that of a merman. In this state, Gyokko retained his facial features and muscular physique but now possessed a more humanoid body with two large arms replacing his many small ones, along with webbed hands with turquoise scales and sharpened fingers. Although he still didn't have legs, Gyokko instead acquired a long, teal, serpent-like tail in place of them. Gyokko also grew much larger, became covered in transparent scales, and attained dark markings on various places around his body. While he still kept his cornrow-styled fin "hair", Gyokko obtained a lot more blue-violet fins throughout his body; he had long mane comprsied of fins, and they also lined up the top-half of his tail. In addition, the mouth which displayed his lower eye had 4 stitches, with 2 on each side, giving it a rag-doll like appearance.

Overall Abilities
Gyokko imprisons a Hashira in a matter of seconds. 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 easily outclass the average demons and give him the necessary edge to 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 than Gyutaro and Daki, the former having killed 15 Hashira and the latter having killed 7. Gyokko has displayed many impressive feats, such as spawning a plethora of powerful demon-like creatures, such as goldfish-like demons, and mackerel-like demons,with unique attacks, and highly unorthodox movement both within and out of his pots, and a second hidden form. Most notably, in his duel with Muichiro Tokito, Gyokko was able to overpower and hold the Mist Hashira back for the majority of their fight, even managing to bring him to 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 than likely been able to kill him. Talented Artist: Due to his obsession with pots, Gyokko became very skilled at painting and making them, so much so 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.
