Nezuko is at least stronger than Daki, meaning that if Muzan could bring her back under his control, she would certainly qualify for the most prestigious title a demon can hold: a member of the Twelve Kizuki. Thanks to Nezuko's remarkable strength, she would have to be an Upper-Moon.
In the grand scheme of things, Daki is far more formidable and experienced than Nezuko, with plentiful specific abilities at her disposal.
Nezuko Obliterated Daki with Blind Rage.
Nezuko is easily one of the most powerful demons in the Demon Slayer series, possibly due to the large quantity of blood she was given by Muzan. But what makes her a truly terrifying opponent is her willpower, being the only other demon after Tamayo to escape Muzan's control.
In conclusion, Nezuko cannot beat Akaza in Demon Slayer. In terms of power, physical abilities, regeneration rate and overall combat ability, Akaza is far superior compared to Nezuko.
Nezuko beheads Daki. Before Daki can decapitate Tanjiro in retaliation, Nezuko appears behind her and destroys her head with a powerful kick.
As a member of the Upper-Rank Six, Daki was extremely powerful. She was much more powerful than the regular demons. Her physical abilities were on a completely different level in comparison to some demons that Tanjiro and co. had faced. Daki was immune to decapitation when her brother was attached to her core.
Nezuko's rankings in the popularity polls are as follows: Nezuko ranked 3rd place in the first popularity poll with 3,319 votes. Nezuko ranked 11th place in the second popularity poll with 5,000 votes.
Apart from Tanjiro, the show centers on his younger sister Nezuko Kamado, turned into a demon by Muzan Kibutsuji. Demons are incapable of walking out in broad daylight because the sunlight will burn them into the ashes. However, Nezuko has immunity against the sun, so she was given the name “The Chosen Demon”.
5 Blood Manipulation – Gyutaro
The strongest technique facilitated by the Blood Demon Art is Gyutaro's Rotating Circular Slashes: Flying Blood Sickles. It is nigh-unavoidable and can spread over a wide area, also capable of destroying multiple structures and houses.
1. Gyomei Himejima. Gyomei Himejima, the Stone Hashira, is the strongest Hashira in the Demon Slayer corps in terms of strength and swordsmanship. He is the only person who uses spiked flails and an axe instead of standard swords to kill demons.
With this in mind, if Nezuko had also been murdered by Muzan, Tanjiro would have no reason to be empathetic toward demons. Her transformation gave him a perspective of both demons and humans, but without Nezuko becoming a demon he would have no reason to take their feelings into account.
Abnormal Demon Physiology: As the "chosen demon", Nezuko has several unique demonic traits that set her apart from all other demons. Most notably, Nezuko can continuously restore her power without consuming any human blood like any other demon would need to do.
She Is Over 100 Years Old
Even though Daki has a youthful appearance, she is actually over 100 years old. Many of Muzan's demons look young, but it is especially surprising to learn that Daki is one of the oldest demons.
Daki is highly sexualized despite being biologically thirteen years old. While it could be argued that her sexualization is part of her story, as she is a courtesan, it still can leave more mature fans feeling a little weird.
Though now he's on his way. Daki too has reached new heights of power. She absorbs the remains of the belt demon, her hair turns white and green, and she gets uh, more veiny. But she is shocked when Tanjiro's Sun Breathing not only cuts through her belts, but actually burns her.
Akaza was also one of Muzan's favorite demons out of all his subordinates. The reason behind this is Akaza's extreme loyalty to his master. The Upper Rank Three demon was always sent away on special missions, something the Upper Rank 1 and 2 were often denied of.
At some point, Daki fought, killed and ate seven Hashira. Two days before Tanjiro Kamado and company infiltrated the Entertainment District, Daki was confronted by Omitsu, the manager of the Kyogoku House, over her mistreatment of the staff.
Upper-Rank Five: Gyokko
As a fellow artist, Gyokko became distracted by Haganezuka's dedication to sword-polishing and opted to hold off on finishing off a wounded Muichiro. Tokito then manifested his Mark and effortlessly decapitated Gyokko with Mist-Breathing, Seventh Form: Obscuring Clouds.
Hearing the response, the young protagonist resumed the fight and was able to outclass the Upper Moon demon. Tanjiro's sun-breathing technique, Hinokami Kagura, allowed him to cut through Daki's obi sashes with ease.
Nezuko's most significant trait, however, is her immense growth, which is likely due to a combination of the amount of blood she received from Muzan and her willpower. To conclude, Nezuko is a formidable powerhouse within the anime and is probably one of the strongest main characters in the series.
The warrior Muzan feared was a swordsman named Yoriichi Tsugikuni. Yoriichi was the only slayer before Tanjiro who came close to killing Muzan, and the flashback of their fight occurred in Chapter 187.
1. Nezuko. Nezuko, also a part of our strongest characters in the Demon Slayer list, is one of the most powerful female characters in the anime. Just by being a demon, she is more powerful than all the human characters in the series.
However, in later volumes, the muzzle is removed and she gains the power of speech in volume 22 then remembers everything and gets her human thoughts again and remembers her name, albeit very broken due to not speaking for more than two years.
