Nezuko Kamado can walk in the sun because she's a unique demon whose physiology adapted after consuming the Blue Spider Lily, a rare flower Muzan sought, granting her sunlight immunity, combined with her strong will, family's Sun Breathing lineage, and never eating humans, allowing her to eventually transform into a human again, not just a sun-proof demon.
Nezuko's immunity to sunlight in Demon Slayer may come from eating the Blue Spider Lily, as shown in the anime's finale. The Blue Spider Lily's significance adds depth to Muzan's failure, highlighting his contempt for humanity in the series.
In Demon Slayer, only two demons are known to be immune to the sun: Tanjiro and Nezuko Kamado.
Also the reason why Nezuko was already so powerful is because Muzan injected tons of blood in her body and the others in hopes of creating a demon that could conquer the sun.
DK tanjiro is immune to sun: This would render yoriichis sun breathing useless because it wouldn't kill him 2. DK tanjiro has instantenous regeneration.
While the Demon Slayer Mark typically brings a short life, ending around age 25, manga evidence suggests Tanjiro did live past 25, marrying Kanao and having children, dying of old age, not the curse, after defeating Muzan and living in an era of peace, possibly due to his connection to Yoriichi and the curse being lifted.
The first possible reason is that Nezuko hails from a family that uses Sun Breathing as Hinokami Kagura. Being generationally connected to a community that dances as an offering to the sun gods may have resulted in Nezuko's immunity to the sun.
One of the most emotional and saddest backstories of all is that of Gyomei Himejima, the Stone Hashira. He's not just the most powerful fighter in the Demon Slayer Corps. He's a person who had everything taken from him, long before he wielded a katana.

The only canonically LGBTQ+ character in Demon Slayer is Suma, one of Tengen Uzui's wives, who is confirmed to be bisexual and polyamorous in the series' databooks, showing affection for both men and women, including Tengen and her fellow wives, Makio and Hinatsuru. While other characters like Mitsuri are speculated to be queer, Suma is the sole officially confirmed character, with her relationship dynamic highlighting both bisexuality and polyamory within the Demon Slayer Corps.
Unlike other demons, Nezuko is special—she doesn't injure humans and battles to protect them with her brother. Yet by the end of Season 3, all of that gets turned on its head. For Nezuko, she's able to survive in the sunlight. This is something that no other demon has been able to do.
Tanjiro stands out because he isn't some “chosen one” or descendant of greatness. He's just an ordinary boy who became extraordinary through sheer effort and willpower. Hard work > destiny 😊 His bloodline still inherits the Sun Breathing technique from Yoriichi.

Upon seeing her for the first time, Zenitsu falls in love with Nezuko at first sight.
As an Oiran, Daki was very mean and cruel. She yelled at any servant or helper in the Kyogoku House and got angry with anyone who touched her or got in her way. She also liked to eat only people she thought were pretty or strong.
One of the reasons people might consider Shinobu the "weakest" Hashira is because, unlike the others, she can't behead demons, which is usually the easiest way to kill them. Instead, she uses poison to defeat them.
✅Breathing technique Yoriichi created the breathing technique known as Sun Breathing, which he modified to teach to other Demon Slayers. The variations he created became the Water, Wind, Flame, Stone, and Thunder Breathing techniques.

Beneath Meliodas' frank and bawdy demeanor hides immense amounts of emotional pain from having witnessed Elizabeth die over 106 times.
While many Hashira died in the fight, some survived: Giyu Tomioka, the Water Hashira, and Sanemi Shinazugawa, the Wind Hashira, both survive the final fight, carrying on the memory of their fallen comrades. Tanjiro also survives, and after the war, the Demon Slayer Corps disbands because demons are gone for good.
