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.
Overall Abilities: As the secondary holder of Upper Rank Six, Daki was an extremely powerful demon with over a century of fighting experience, having killed and devoured seven Hashira in the past.
Shinobu Kocho is a capable Demon Slayer whose worthy of being the Insect Hashira. That being said, she's arguably the weakest Hashira when it comes to pure strength.
The number engraved in their eyes represents how strong each Demon is. Upper Moon One is the strongest while Lower Moon Six is the weakest.
In the grand scheme of things, Daki is far more formidable and experienced than Nezuko, with plentiful specific abilities at her disposal.
Given that she survived the Final Selection, she has excellent combat abilities. But Nezuko single-handedly overwhelmed Daki, showing just how strong she is as a demon. Therefore, it can be assumed that Nezuko would be able to beat Aoi if the two engaged in combat.
On the contrary, Tengen was able to sneak up behind and decapitate Daki with no problem during the Entertainment District arc. Tengen also has immense strength, stamina, and endurance, accredited to both his Shinobi and Demon Slayer training.
Tengen Uzui
He is the fastest Hashira, and the second physically strongest. Obviously, then, Tengen Uzui is rather proud. He is demanding, fussy, boastful, and prone to selfishness. But he is also ultimately kind and caring, with great love for his three wives as well as the other Hashira.
Kokushibo was the final Upper-Rank to die during Demon Slayer's "Infinity Castle" arc. Muichiro, Genya, Sanemi Shinazugawa and Gyomei Himejima fought together against Kokushibo, though Muichiro and Genya were no match for him and were killed.
After becoming a Demon Daki grew strong enough to kill and eat seven Pillars and gained the attention of Muzan Kibutsuji who allowed them to join the Twelve Demon Moons. She later dies after being beheaded by Zenitsu Agatsuma and Inosuke Hashibira.
Demon Slayers are known for their strength and bravery in battle, but not Zenitsu. Despite his cowardice, he's one of the strongest in the series. The life of a demon slayer is one of hardship.
3 Nezuko Is The Friendliest Demon In The Series
A few demons have proven that they're capable of coexisting with humans in the series, such as Tamayo and Yushiro. However, Nezuko is the friendliest demon anyone will ever meet.
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.
Daki was obsessed with beauty and if she saw a beautiful human, she immediately grew the need to eat them. With the help of her Obi, Daki would trap her prey and store them inside the Obi. This allowed Daki to consume the trapped people at her leisure.
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.
In the end, Tanjiro lands a finishing blow to Hantengu's real body. When Hantengu pushes Nezuko into the sunlight, Tanjiro uses Sun Breathing Technique in a moment of desperation and swiftly defeats the Upper Moon.
Fortunately, Zenitsu was able to single handedly beat the Upper Moon 6. Not only did he defeat the demon, he also created a seventh form called the Flaming Thunder God. These are the demons who have been given the title of Upper Moon 6 in Demon Slayer.
Upper-Rank Two: Doma
Kanao Tsuyuri and Inosuke then teamed up to fight, but were no match for him until the 37 kilograms of Wisteria poison he'd inadvertently ingested by consuming Shinobu began to melt his body.
But, comparing the two characters in their best forms, Zenitsu might be just a tad bit faster owing to his Godspeed move.
Sanemi is clearly the least popular Hashira among Demon Slayer fans.
Rengoku's fight in the Mugen Train arc showed his incredible speed and reflexes. He was able to match Akaza's speed, and his movements were so fast that it was almost impossible for the naked eye to keep up. Tengen, meanwhile, is the fastest runner out of all the Hashira.
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.
Akaza's rank is far superior to that of the Gyutaro and Daki, and an upper-rank demon is more powerful than the demons with a lower rank. That said, this fight will be two against one. In order to mark his victory, Akaza has to defeat both the sibling demons which can be a bit hard.
Though Inosuke has run into a number of battles in which he was unable to claim victory, he has grown much stronger and was able to decapitate Daki for a second time, to disastrous results.
