In the dark world of Demon Slayer: Kimetsu no Yaiba, the Upper Moons represent some of the most fearsome and powerful demons to ever walk the earth. Led by Muzan Kibutsuji, the villainous progenitor of demons, the Upper Moons have become an iconic part of the Demon Slayer universe, showcasing complex personalities and terrifying abilities. Whether you’re a fan of Demon Slayer’s intense battles or its rich lore, the Upper Moons are undeniably some of the most compelling characters in the series.
But what if you could bring these characters, or your very own Demon Slayer original character (OC), to life in new, exciting ways? With the advent of AI-powered comic book generators and OC makers, fans can now use cutting-edge tools to create stunning visuals and explore their creativity by designing unique images based on their favorite Demon Slayer characters—or even generate new demon slayers of their own.
Who Are the Upper Moons in Demon Slayer?
The Upper Moons are elite demons in the Demon Slayer series, each one serving as a high-ranking member under the command of the main antagonist, Muzan Kibutsuji. Each Upper Moon demon is not only immensely powerful but also carries their own distinct personality, abilities, and tragic backstory.
Let’s explore some of the standout Upper Moons:

1. Upper Moon One: Kokushibo
Kokushibo is a tragic and formidable antagonist, once a human swordsman named Michikatsu Tsugikuni, who became a demon after seeking immortality. As the highest-ranking Upper Moon, Kokushibo is a skilled swordsman, combining his mastery of the sword with the demon abilities he gained from Muzan. He is calm, calculating, and terrifyingly powerful, with the ability to manipulate his own flesh to create deadly, monstrous forms. His visual design, with his intricate and eerie armor and twin-swords, is one of the most striking in the series.
2. Upper Moon Two: Doma
Doma is one of the more eccentric and unsettling characters among the Upper Moons. As the leader of the Eternal Paradise Cult, Doma presents himself as a cheerful and charismatic demon, masking his sadistic nature. His fighting style is based on using his ice powers, making him a dangerous and unpredictable opponent. His design, featuring a haunting smile and unique attire, stands out as one of the most memorable.
3. Upper Moon Three: Akaza
Akaza’s tragic past as a human martial artist who lost his loved ones makes him one of the more complex characters in Demon Slayer. As Upper Moon Three, Akaza is a highly skilled fighter who excels in hand-to-hand combat, making him a particularly formidable adversary. His personal vendetta against the Hashira (Demon Slayer Corps’ elite) creates a fascinating conflict within the story. Akaza’s striking visual design, with his blue markings and intense gaze, makes him a fan favorite.
4. Upper Moon Four: Hantengu
Hantengu is a unique demon, divided into multiple personalities that each possess their own distinct abilities. His form can morph, allowing him to utilize a variety of deadly techniques to confuse and overwhelm his enemies. He has smaller, almost childlike demeanor, paired with the cruelty of his other personalities, makes Hantengu a particularly unsettling figure. His design is both fascinating and grotesque, making him a standout among the Upper Moons.

5. Upper Moon Five: Gyokko
Gyokko is an artistic and deranged demon who takes pleasure in the grotesque. His ability to create horrifying creations from the corpses of his victims and his bizarre, fish-like appearance make him one of the more unnerving Upper Moons. His powers are centered around manipulating water and creating deadly traps, making him a difficult opponent to defeat.
6. Upper Moon Six: Kaigaku
Kaigaku was once a member of the Demon Slayer Corps before he turned to Muzan, and his fall from grace makes him one of the more tragic figures in the series. As Upper Moon Six, Kaigaku wields the power of lightning and is an antagonist with a high level of animosity towards Zenitsu Agatsuma, a fellow swordsman. His design, with his long hair and ruthless attitude, highlights his role as a significant antagonist.
