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.
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.
Overall Abilities: As the true Upper Rank Six, Gyutaro was an extremely powerful demon with over a century's worth of combat experience under his belt, having killed and devoured 15 Hashira in the past.
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.
Daki was stronger than most demons, but she was not strong enough to be a member of the Upper-Rank Six. As the arc progressed, it became clear that Daki did not have enough strength to fight against a Hashira, and Muzan's comments about her killing seven Hashira were untrue.
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.
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.
Muzan is shown to have a positive master-servant relationship with Daki, as the young Demoness seemingly worships and admires the Demon Progenitor immensely, fervently hanging on each and every one one of his words and doing her absolute best to accomplish the tasks he gives her.
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.
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.
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.
The Upper Moon 6, a cruel demoness named Daki, may have lost to Tanjiro and Tengen in the end, but she could defeat a wide variety of heroes from other anime if they tried to slay her.
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.
The Upper Moon Five has a record of killing 15 Hashira in the past, solidifying his position in the Twelve Kizuki.
Shinobu Kocho was the former insect Hashira who played a big role in defeating Doma, the Upper Moon 2, during the Infinity Castle arc. Doma overwhelmed her with his power and Blood Demon Art. However, she decided to let him consume her since she had enough poison in her that would make him vulnerable.
In the eighth episode of the "Entertainment District" arc, Upper Six Gyutaro couldn't stop gushing over his man-crush on Tengen.
Trivia. Anne was originally planned to be Muzan`s older sister, who died by the hand of a Demon Slayer but that idea was scrapped, as the author knew practically nothing about Muzan`s early life. Instead, Anne became his wife, by which he had two children.
The only Demon he despises the most is the Upper Rank Two: Doma. It is quite a shocker that the second most potent Demon in the Demon Slayer is not Muzan's favorite.
Daki received a third eye that Gyutaro had implanted on her forehead. Her reflexes were quicker, her movements were sharper and her strength improved quite drastically. If we take a closer look, it was Gyutaro's left eye that was implanted on her forehead.
3 Muzan Mainly Liked Daki Because Of Her Potential To Earn Money. Given how easily Muzan would destroy any demon who didn't have any use for him, people have to wonder how he managed to be so tolerant for Daki's sake even though he already held the notion that she wasn't the brightest of the lot.
Now since we know Daki's human age is 13 and both she and Gyutaro have been demons for only 100 years, we now know that Daki is officially 113. Everyone understands that she is 113 but the confusion is when Gyutaro's overall age was stated to be 126.
1. Gyomei Himejima – The Stone Hashira.
Shinobu Kocho Is the Weakest Hashira
Of the three Hashira who were killed by Upper-Ranks -- Rengoku, Shinobu and Tokito -- Shinobu was the only one who was killed almost instantly when she encountered Doma, Upper-Rank Two.
