OtapediaGyokko - Kimetsu no Yaiba (Demon Slayer)

Gyokko (玉壺 Gyokko) is a member of the Twelve Demon Moons and holds the position of Upper Moon Five in the Kimetsu no Yaiba (Demon Slayer) series. Gyokko's appearance is the most demon-like out of the Upper Moons. His upper torso is in a human shape but instead of arms connected to his shoulders he has many child sized arms appearing from all over his body, including his head. His lower half is constantly inside a pot and when he finally shows his whole body we see that he can transform his body to seem more mermaid like with scales covering his body. Gyokko has pale white skin and an unusual facial position. Where human's eyes would be he instead has two green colored mouths and where his mouth should be is an eyeball, his other eye being situated on his forehead vertically. His eyes are red and yellow in color with the kanji for Upper Moon Five written on them. He has three brown circles around the eye on his forehead and blue purple coloured protruding strips which could be his hair.

"Well, well. Akaza-sama! Dear me, you seem to be looking swell. The mere possibility of you dying made my heart leap with jo- coughcough made my heart cringe with pain."
—Gyokko to Akaza, Demon Slayer Chapter 98


  • Race: Demon
  • Age: 100+years (Mentally)
  • Manga Debut: Chapter 98
  • Status: Deceased


Gyokko first appears when he is summoned into the Dimensional Infinity Fortress by Nakime for a meeting. Muzan Kibutsuji summons the Upper Moons after the death of Daki and Gyutaro and expresses his disappointment towards the Upper Moons not able to provide him the information he wants. Gyokko is the only one with useful information but Muzan Kibutsuji rips his head off since his information is not fully confirmed. Even though Gyokko holds important information about the location of the hidden blacksmith village he shows joy when Muzan Kibutsuji touches his head despite it being ripped off. Afterwards he is seen infiltrating the blacksmith village and starts killing the swordsmiths thinking that by destroying the blacksmith village it would greatly weaken the Demon Slayer Corps. He is then killed in a fight with Muichiro Tokito the Mist Pillar who decapitates him.


Gyokko is a sadistic Demon with a morbid sense of humor. He fails to hide his disappointment when he sees that Akaza is still alive and when talking to Doma about planting a female head in one of the pots he had received Gyokko expresses interest at the thought. When he meets Muichiro Tokito he immediately showcases his ‘art’ which is a mash of five, still alive, blacksmiths with swords impaled into him. Gyokko is also short tempered and incredibly shallow. He is easily angered when Muichiro Tokito badmouths him a little and insults his art. He thinks of himself as beautiful and is shown to be very narcissistic, telling Muichiro Tokito to prostrate himself before his 'perfect beauty'. He is also shown to be very jealous. When he sees Hotaru Haganezuka, a blacksmith, so focused on his work that he didn't even notice the Demon even when he called out to him, Gyokko compares themselves. He is then greatly frustrated since he has never been able to concentrate as hard as Haganezuka and feels as though he lost as an artist. Therefore he decides to attack Haganezuka, trying to make him abandon the blade he is sharpening.
