Demon Slayer is one of the most popular and beloved anime series out right now, with Ufotable's stellar animation elevating this series to a whole new level. The first season was one of the biggest and most beloved anime around, with each episode being absolutely memorable in its own right. The latest few episodes of Demon Slayer episodes have been pretty notable in their own right, introducing the duo of Daki and Gyutaro that would terrorize Tanjiro and his comrades.
The joint Upper Rank 6 demons are quite intriguing, and it's only a given that most people would want to know everything possible about these creatures. Daki herself is quite an enigma, with this character having several facts that most people simply aren't aware of. Here are some unique things about this character that fits perfectly within this context.
6 Daki's Name Contains The Japanese Characters For Degenerate And Princess
Daki has one of the saddest backstories in the entire series. She never even wanted to turn into a demon but was forced into becoming one after being burnt alive at the hands of a pushy client, leading to a desperate Gyutaro accepting the notion of becoming a demon so that her sister could remain alive.
Given how beautiful Daki is, it's a shame that the background she was born in was filled with tragedy to the point that it led to her becoming a villain as well. Her name is reflective of her situation, with Daki containing the Japanese kanji for both 'degenerate' (da) and 'princess' (ki). In a way, her identity of being a fallen princess is apt given the struggles she's faced.
5 It's Possible That Her Mother Died Because Of Syphilis
Daki was never the name given to the demon at birth. As a human, Daki was known by the name 'Ume' instead. This was a rather peculiar choice for a name, especially since Ume was the disease that killed Daki's mother! While the death of Daki's mother was anything but tragic — given how abusive she was — his name does hint towards the manner of her demise.
Since Daki and Gyutaro's mother was also a prostitute, it wouldn't be a stretch to say that an STD was what led to her demise. Most people believe that the nature of this disease was syphilis, known as 'baidoku' in Japanese. This is because the words for 'Ume' and 'Bai' are interchangeable in Japanese.
4 Both Gyutaro And Muzan Didn't Find Daki To be All That Smart
Daki might be one of the most powerful women around, but that in no way indicates that she was smart by any course of the imagination. After all, she was an extremely impressionable child and preferred to jump into things headfirst instead of actually strategizing and taking the smarter course of action instead.
This is a sentiment echoed by both Gyutaro and Muzan as well, who don't really find Daki to be all that intelligent. Of course, Gyutaro deserves to shoulder the blame for this since he never really helped develop Daki's intellect and took advantage of her impressionable nature to force her into a career instead of letting her think for herself.
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. However, demons have other uses than just being smart, and Muzan recognized this in Daki as well.
Any organization, whether run by humans or demons, requires a reliable source of income to manage itself. Muzan's organization is no exception to this rule, and the demon decided to keep Daki enrolled because of her potential to earn money. Her background as a courtesan coupled with her beauty meant that she would serve as a great and reliable source of income for Muzan, which is why the Demon King decided to be tolerant of her apparent stupidity.
2 Daki Was Never The True Holder Of The Upper Rank 6
While Daki is definitely a powerful demon that deserves to be held in high regard, there's no denying the fact that she didn't really have the power required to become a part of the Upper Rank demons. The fact that she teamed up with Gyutaro meant that she could break into these ranks, with the sibling duo establishing themselves as one of the most powerful demonic pairings around.
However, Daki was never the true holder of the Upper Rank 6 in any way. As discussed before, her headstrong nature in battle meant that she was bound to leave herself open at some point or the other. The true holder of this rank was always Gyutaro, whose level-headed nature meant that he could be both the brains and brawn of the operation if need be.
1 Her Ability To Extend Her Neck Is Inspired From The Legend Of The Rokurokubi
Daki's Blood Demon Art is pretty intriguing, with her ability to extend her neck being one of the most intriguing parts of her character. This ability is pretty unique and actually takes inspiration from a legendary Japanese yokai.
The Rokurokubi is a demon who could either extent or split its head from its body. This horrific tale has inspired Daki's powers in Demon Slayer, making this particular demon a force to be reckoned with.
