Gyokko/Relationships

Doma
Gyokko, one of the Twelve Kizuki and Upper Rank Demons in the Demon Slayer Corps, had a unique relationship with Doma. The two were known to be semi-friendly towards each other, even chatting before the arrival of Muzan Kibutsuji the Upper Ranks Meeting. They seemed to have a mutual respect for each other, despite their different personalities and approaches.

In combat, Gyokko was known for his speed and precision, relying on his whips and sharp weapons to quickly take down enemies. He also had the ability to use his blood demon art to form his blood into sharp weapons. Doma, on the other hand, was known for his cold and cunning approach, using his ice breathing techniques to freeze his opponents and leave them vulnerable. Doma's friendliness towards Gyokko though, was probably a part of Doma's act.

Akaza
Akaza, one of the Twelve Kizuki Upper Demons, and Gyokko, Upper Rank 5, had a complex relationship. Akaza was a powerful and menacing demon who used martial arts and a blood demon art to create shockwaves. Gyokko was known for his use of blood demon art to create blood monsters to attack his enemies. He was also known for his playful and arrogant personality, often taunting and mocking his opponents during fights.

They were both members of the Twelve Kizuki, and as such, were considered among the strongest demons in existence. They also both had a deep devotion to Muzan, the leader of the demons, and would do anything to serve him and help ensure his ultimate goals were achieved.

However, there was also a sense of rivalry between Akaza and Gyokko, as they were both powerful warriors. Despite this, they seemed to be able to put their differences aside when necessary to fight against the Demon Slayer Corps and protect Muzan's interests.

Muzan
Muzan Kibutsuj is the main antagonist and leader of the demons. He is a powerful and cunning demon with vast knowledge and skills in combat. He is also known to be the origin and creator of the Twelve Kizuki, the Upper Rank demons that serve under him.

Gyokko is one of the Twelve Kizuki, known for his use of blood demon art to create blood monsters to attack his opponents. He is also known for his playful and arrogant personality, often taunting and mocking his opponents during fights.

While their relationship is not explicitly stated in the series, it can be inferred that Gyokko is loyal to Muzan, just as the rest of the Twelve Kizuki.

Hantengu
While not much is known about their relationship, it is apparent that they have a level of respect and camaraderie with each other. Despite their differences in personality and style, they seem to complement each other's skills and abilities, working together effectively and efficiently to complete their missions.

Their level of competency together is probably high, making them a force to be reckoned with. They are both highly skilled in their respective combat styles and have shown their ability to adapt to various situations. They are a highly capable and formidable team, with their individual abilities complementing each other to create a deadly combination. They were both committed to the mission at the Swordsmith Village, and stopped at nothing to try to complete it.

Muichiro Tokito
Gyokko, one of the Upper Demon Moons, saw himself as superior to all Demon Slayers, Muichiro included. He took great pleasure in tormenting Muichiro, and often mocked and taunted him while fighting. Muichiro, on the other hand, was one of the most talented and skilled Demon Slayers in the Corps. He was confident in his abilities and determined to protect his fellow humans from the demon's wrath. Gyokko took notice of Muichiro's strength and potential, and was determined to eliminate the Demon Slayer before he grew into an even bigger threat. They are hostile towards each other.

Hotaru Haganezuka
Their relationship is one of enemies. Hotaru sees demons as nothing but a threat to humanity, including Gyokko. He is always ready to destroy any demon he comes across, including Gyokko. Gyokko, on the other hand, sees Hotaru as nothing more than an obstacle in his path to achieving his goals. He has no respect for Hotaru and will stop at nothing to defeat him.

Despite their differences and the fact that they are on opposite sides, they both have immense strength and skill. Hotaru has a unique talent for modifying weapons, while Gyokko has the ability to create and control blood monsters in battle. Gyokko is also one of the most powerful Upper Rank demons, making him a formidable opponent for even the most seasoned demon slayer.
