Hantengu is a very powerful demon and should be avoided. He is able to clone or split himself into multiple bodies through his Blood Demon Art. Doing this confuses and overwhelms his opponents, they just don’t know which of his clones is the real Hantengu making it really difficult for them to fight back effectively.

Hantengu can also change his size at will. He can become incredibly small allowing him to hide if the battle is not really going his way.

Gyutaro is Daki’s elder brother and the true holder of Upper-Rank Six.

He is the main demon of the Red Light District Story Arc

He possesses the ability to create a strong psychic connection with Daki by removing and merging one of his own eyes into his sister’s forehead allowing him a way to fight while manipulating her, enhancing her abilities and powers in battle.

Gyutaro can also detach flesh and blood from his body and form them into weapons. When he uses these weapons they become even more powerful when combined with his Blood Demon Arts.

Daki is the sister of Gyutaro and a very powerful demon with more than 100 years of fighting experience. She is responsible for killing and devouring seven high-ranking Hashira.

She is a very sadistic demon, taking huge enjoyment in playing with her victims before killing them. She never showed any guilt or remorse for her murderous actions and the devastation they caused.

Gyokko’s Blood Demon Art and powers give allow him all that he needs to defeat and kill even the Demon Slayer Corp’s most talented Hashira. He is more powerful than both Daki and Gyutaro and has displayed many impressive feats of strength with a great example being when he fought Muichiro Tokito.

He was able to overpower and hold the Hashira back for the majority of their fight. It was Gyokko’s egotistical nature that was to be his downfall and Muichiro’s use of his Demon Slayer Mark.

We see the extent of the powers that Enmu possesses during the Mungen Train Arc. We learn that he is able to enter her victim’s dreams and manipulate them to his will. The powerful mind games trap his opponents in their own nightmares, making them unable to fight back and effectively disarming them.

He is a Demon that is cunning and manipulative and loves nothing more than to psychologically torment his opponents.




Rui really is one of the strongest demons to have ever appeared in Demon Slayer.  His strength and abilities were superior to most other demons. This was seen when Rui was easily able to conquer and control numerous demons of Mount Natagumo. He was able to force them to work for him and referred to them as members of his family.

Demons empowered with his blood were strong enough to kill many of Demon Slayers easily.

Nakime doesn’t possess much in the way of fighting skills but she is still an extremely powerful demon. With her Blood Demon Art, she was able to kill Obanai and Mitsuri with her skilled opponents not being able to harm a hair on her head.

She was also able to create several eyes and then detach them allowing her to spy on others from a long range. This ability allowed her to successfully find and locate the positions of the Demon Slayer Corps gaining huge advantages.




Kyogai is a very powerful demon and one of the most powerful that Tanjiro has faced to date. He is known as the “Drum or Drumming Demon” due to his strange ability to control people through a hypnotic drumbeat.

With Tsuzumi Drums embedded in different parts of his body, he only had to hit them to enact a certain effect on his surroundings. The downside to his drumming power was that the range the drums effected was limited to the interior of his mansion

During his epic battle with Tanjiro, he is able to demonstrate incredible strength and speed and his mastery of martial arts.
