Demon Slayer: Kimetsu no Yaiba is a Japanese manga series written and illustrated by Koyoharu Gotouge and has been deemed as one of the most popular shonen jump series. Sold over 150 million copies as of 2021 and also had a record run in the Japanese Box office by becoming the highest-grossing film in history. With different characters, elements, and a narrative storyline like other shonen series, Kimestu no Yaiba shines in its own way.
Notable characters such as the Hashira’s and the Twelve Kizuki’s are what make the series even more interesting. The Twelve Kizuki or the Twelve Moons is an organization consisting of the twelve most powerful demons which are under the direct command of Muzan a.k.a the Demon king.
The twelve moons are divided into two groups namely the Upper Moons and the Lower Moons. The Upper moons are basically the strongest among the two groups and are ranked accordingly from the strongest to the weakest in power and combat. And in this post, we are going to discuss the strongest demons in the series and rank them accordingly.

Top 15 Strongest Demons in Demon Slayer Ranked-
15. Susamura –
Susamura was introduced in the Asakusa Arc where she displays her incredible physical strength and fighting abilities using her Temari. By manipulating her flesh she could grow four more arms amplifying her offensive output.
Her blood demon art allows her to conjure Temari at will which she can either throw or kick at incredible speed and power. Although she was strong, Tamayo easily deceives her, and Kibutsuji’s curse kills her which is why she is ranked 15 on the list.
14. Yahaba –
Also known as the arrow demon appears in the Asakusa Arc who fights along with Susamura. By manipulating his own flesh, he can morph two eyes on his palm with arrows for irises but also at the cost of his regular eyes.
Using his blood demon art, he can track other demons and also manipulate matter and interactions through their related vectors using his Koketsu arrows.
He was defeated by Tanjiro who used the vectors by enveloping them to his water breathing technique and used that momentum to direct his attack. Since his blood demon art can be evaded by following the direction of the vector, he is ranked 14 on the list.
13. Rui ( Lower Moon 5) –
Rui first makes an appearance in Episode 15 of the Natagumo Mountain Arc. Rui was one of the Lower moons who possessed incredible powers and superhuman strength and durability.
Just like Muzan, Rui could also strengthen a fellow demon by giving them his Demonic blood. He had traits like that of a spider and also created and manipulate steel thread using his blood demon art. His steel threads could still be cut by Tanjiro and burned by Nezuko so he is ranked 12 on the list.
12. Enmu ( Lower Moon One) –
Enmu first appearance was in the Rehabilitation training arc and also appears as the antagonist in the Mugen Train Arc. As one of the twelve Kizuki, Enmu possesses enhanced speed and reflexes, which evade attacks with ease.
As a demon, Enmu can manipulate flesh to attach himself to inanimated objects and also detach his own flesh making a clone of himself to fool others.
By using his blood demon art, he can manipulate dreams and also put his target to sleep by mixing his blood with other fluids making them vulnerable. Although his blood demon art is strong it’s not invisible since it can’t affect other demons like Nezuko and can be blocked if one’s viewpoint is changed. Hence, he ranked 13.
10. Kaigaku (Upper Moon 6) –
Kaigaku was a former demon-slayer turned demon who was also the senior disciple of Zenitsu Agatsuma who both trained under the Thunder Hashira. As a former demon slayer, Kaigaku was definitely one of the strongest upper moons.
He could enhance his thunder breathing style and produce electricity using his demon blood art. Even though he became a demon and enchanted his thunder breathing techniques, he was still defeated by Zenitsu that is why we place him on rank 10 on the list.
11. Gyutaro ( Upper Moon 6)
Gyutaro was one of the Upper Moons who was introduced in the Entertainment District Arc alongside his sister Daki. As one of the Upper Moons, Gyutaro has immense regenerative abilities, speed, and power.
By manipulating his own flesh he can turn them into sharp sickles and also detach his cells and merge with his sister to boost all of her powers. His blood demon art allows him to manipulate his own blood creating sharp objects and controlling them at his own will and can also use it as a lethal poison to kill his target. Nezuko could easily heal the lethal poison using her blood demon art during the battle and so he ranks 11 on the list.
9. Gyokko ( Upper Moon 5) –
Next on our list is the Upper Moon 5 Gyokko, who in fact is a disfigure humanoid and has only a torso with infant-like hands on his back and grows out of a porcelain pot and looks similar to that of a djinn.
This demon can be seen in the Swordsmith village arc where he fights Muchiro. Using his blood demon art he can materialize pots out of thin air, manipulate water and transmute the objects into fish when he touches them. He was defeated by Muchiro after awakening the demon slayer mark and thus he ranks 9 on the list.
8. Hantegu ( Upper Moon 4) –
Hantengu is one of the Upper Moons and also the only demon who could split himself into 6 different demons possessing different abilities of their own. He can manipulate lighting, wind, sound waves, wood, and also spear at his will.
He can even combine his demons into a stronger demon giving him enchanted abilities and offensive power. Hantengu was defeat by Tanjiro after Nezuko sacrificed herself exposing both of them to sunlight, and so he is ranked 8 on the list.
7. Nakime ( Upper Moon 4 ) –
After Hantengu’s death, the mysterious biwas demon, or Nakime became the new Upper Moon 4 as seen in the Infinity castle arc. She was the dweller in the infinity castle who could manipulate and create rooms in the infinity castle by just playing her biwa.
Using her blood demon art, she can manipulate space to a certain extent and also create portals in the form of doors and use them for assisting other demons and herself during battles.
She can also create and detach several eyeballs which can be used as a mode to spy on other people from a long distance. She was killed by Muzan after Yushiro takes control of Nakime’s vision.
Although she isn’t that strong as compared to the other Upper Moons in power and combat, she still managed to fend off two Hashira’s that is the reason we ranked her 7 on the list.

She also possessed immense regenerative abilities like that of an Upper Moon and could even alter her body size by shrinking. She also developed blood demon art and had a pryokinesis likeability which could deal a significant amount of damage to the Upper moons.
Nezuko is the first and only demon to have resistance to sunlight, that is the reason why she ranks 6 on the list.
