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.
When Gyutaro and Ume were found by the former Upper-Rank Six and turned into demons, their lives became permanently intertwined. Daki can't be killed when Gyutaro is inside her body, and when he leaves it, neither one of them can be killed unless they are decapitated simultaneously.
Nezuko beheads Daki. Before Daki can decapitate Tanjiro in retaliation, Nezuko appears behind her and destroys her head with a powerful kick.
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.
Additionally, the only person she adores in a romantic way is Muzan, so its highly improbable that she would admire Douma over Muzan. So no, Daki merely thought of Douma as the demon who saved her and Gyuutaro. Hope this helps. Muzan claimed that Gyūtarō could have won if he fought without Daki.
3 Muzan Mainly Liked Daki Because Of Her Potential To Earn Money.
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.
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.
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 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.
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.
Zenitsu then is slashed by Kaigaku with the Thunder Breathing, Second Form: Rice Spirit.
The explosion, which was enhanced by spike traps, manages to injure Muzan. Before he is able to regenerate fully, Tamayo appears and uses her Blood Demon Art to keep him in place, while using a drug that can turn him into human. Using this opportunity, Gyomei Himejima appears and destroys Muzan's head.
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.
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 most prominent trait Muzan possesses is extreme narcissism, pettiness and an obsession with becoming the perfect being. As he has had over 1000 years to live and observe, along with hardly any real challenges, his extreme egocentrism is almost expected.
Tanjiro decapitates Akaza with the Hinokami Kagura: Setting Sun Transformation. Akaza was bewildered, wondering how Tanjiro did not have any fighting spirit, comparing this feeling to fighting against a plant. He acknowledges that Tanjiro surpassed his speed.
Daki was a demon appearing as a beautiful young woman with a slender and tall yet curvaceous build. Her skin is very pale and has cracks in it. She had two pink flower crescents on her face, with her lime green eyes having the kanjis for "upper" and "six" in them, signifying her rank among the Twelve Kizuki.
At the age of 12 her success all came to an end when she stabbed the eye of a samurai while her brother was away working. Since her brother wasn't present to protect her, she was then tied up and burned alive and left to die in a ditch. Her brother then carried her burnt body around town searching for help.
One can even consider Daki as the more evil between her and Gyutaro since she didn't have as many excuses as her brother. She was raised to be selfish and to only care for herself like a spoiled brat. As a result, she notably caused more trouble for humans than Gyutaro did.
Yet an official Demon Slayer "fanbook," written by the manga's creator, Koyoharu Gotouge, revealed Muzan doesn't really like Upper Rank Two demon, Doma. As Lower Ranks Six, Four, Three and Two can attest, Muzan is not averse to eliminating demons he doesn't care for, even if they're Kizuki.
Technically, the elder of the two Sakuras` was actually Muzan`s child, by way of his mistress (Lady Jade Wong), who had one of her eggs inserted into Anne`s body.
Muzan himself never thought highly of Daki and didn't reciprocate her devotion whatsoever, only ever talking to her to sweetly manipulate her into defeating Demon Slayers on his behalf.
