Nezuko Kamado is one of the most important characters from the Demon Slayer manga. Tanjiro’s little sister, Nezuko was the only survivor of Muzan’s brutal attack on the Kamado family (Tanjiro was not present, so he also survived). In turn, she was transformed into a demon. Being special, Nezuko retained a large portion of her initial humanity and never attacked humans, but she also has some other unique abilities as well, and one of them is her resistance to the Sun. In this article, we will explain how and when Nezuko Kamado managed to conquer the Sun in Demon Slayer: Kimetsu no Yaiba.
Nezuko Kamado managed to conquer the Sun during her battle with Hantengu, but no specific reason was given as to how she was able to do it. It is theorized that Nezuko was able to conquer the Sun because she comes from a lineage of Sun Breathing users and because she kept a big part of her own humanity, i.e., because she never ate human flesh.
The rest of this article will focus on Nezuko Kamado and her dual nature, that of a human and that of a Demon. You’ll find out how Nezuko managed to conquer the Sun and achieve immunity to it, a feat previously thought impossible for a demon.
How did Nezuko manage to conquer the Sun?
Now, we all know that a Demon’s main weakness is the Sun. That is why there are no Demons outside during the day because the Sun would burn and kill them. This is a very specific and innate weakness of theirs and an issue that Muzan had tried to remedy for ages; his search for the blue spider lily, the plant that saved his life, was in part because he thought that it would help him, as a demon, with his weakness to sunlight.
But, while Muzan kept going, other demons had to stay away from the sunlight, and Nezuko was included there. Because she had been transformed into a demon, Nezuko had to be carried in a basket by her brother, Tanjiro, to avoid contact with sunlight during the day because everyone feared the Sun would kill her or kill her injure her gravely.
But, Nezuko being Nezuko, she also had to be unique in this aspect. Namely, as the plot progresses, Nezuko becomes more important to the plot and is a powerful ally of the Demon Slayer Corps. During the Swordsmith Village Arc, Nezuko Kamado fought the Upper Moon 4, Hantengu, who was an exceptionally difficult opponent. At some point, the fight continued until sunrise, and it seemed like Nezuko would go down, sacrificing herself to allow her brother to strike Hantengu, which he could do.
As the sun rose, Nezuko started to burn, but after some initial pain – Nezuko regenerated, stood back up, and started talking! It was a miracle as everyone thought Nezuko would die at that point, but she managed to conquer the Sun; sadly, Muzan was informed about this by the dying Hantengu, which would prove pivotal later on, but that is not what interests us now. What we wanted to know now was how Nezuko could do it.
Well, sadly, an official reason has never been provided, and a lot of elements from Demon Slayer simply remained as facts we have to take for granted. Still, we could theorize about it, and two highly probable reasons could explain her feat. First of all, while Nezuko is not directly related to Yoriichi, she comes from a family of Sun Breathing users (her family knew it as the Hinokami Kagura dance), and that fact could have helped her develop immunity against sunlight.
On the other hand, Nezuko has always been special. Although she was a demon, she still kept a large portion of her humanity, she was rational and aware most of the time, and she even managed to fight off the urge to consume human flesh and blood. This fact definitely shaped her character and probably helped her fight off her demonic traits and conquer the Sun.
