Despite being hundreds of years old and losing all of his human memories, Gyutaro has a strong attachment to his younger sister, Daki. Gyutaro promising Daki that they will always be together.
The only two people she really cares for are Muzan Kibutsuji and her older brother. She shows deep respect for Muzan Kibutsuji immediately falling into a bow when he appears. Although she cares and loves her brother she is seen insulting and blaming him at times when things aren't going well.
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.
The following episode introduces Gyutaro, the elder brother of Daki, who surprisingly holds the same position as her. Gyutaro's emergence out of his sister's body left viewers perplexed about them sharing the position of Upper-Rank Six Demons.
Gyutaro's ability to exist inside Daki's body apparently isn't just so they never have to be apart, but it's also the safest state of being for her. Keeping his sister safe is Gyutaro's only goal in life, so he seemed content to just stay inside her body and let her do as she pleased until she needed him.
In the eighth episode of the "Entertainment District" arc, Upper Six Gyutaro couldn't stop gushing over his man-crush on Tengen.
She Is Over 100 Years Old
Even though Daki has a youthful appearance, she is actually over 100 years old.
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.
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.
DakiTan is the ship between Daki and Tanjiro Kamado.
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.
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.
In fanon they usually portray Douma being comically in love with Shinobu while she despises him, or they both falling in love with each other and developing a romantic relationship despite Shinobu's initial reluctance.
Despite losing his memories, Akaza was noted to have subconsciously retained his strong feelings for Koyuki, this is seen where Doma noted that Akaza absolutely refused to kill and eat women during his hundreds of years as a Demon, despite his obsessive desire for more strength and power.
Demon Life
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.
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.
First of all daki is already shown as a prostitute in the entertainment district arc. She wears these clothes because she has to look seducing.
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.
6) Daki. Given that she is the only demon on this list, it is quite obvious that the Demon Slayer fan base considers her to be a waifu merely for her appearances.
Demon Slayer fans across the web are protesting the series' portrayal of Nezuko, who transforms from a cute young girl to a large-breasted woman. The Demon Slayer fanbase is in a heated debate over Nezuko's adult form - and whether it's appropriate.
Daki disguised as an Oiran named Warabihime.
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.
1 Gyomei Himejima - The Stone Hashira
The oldest of the bunch, the Stone Hashira, Gyomei Himejima is 27 years old. He is a giant with a soft heart who cries over insignificant things, but despite all that, he is easily one of the most powerful Hashiras.
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.
