The Demon Slayer Anime is explained in a Big Mystery that The Manga Hasn't

Demon Slayer: Kimetsu No Yaibaseason 3, may have been the perfect way to end by providing the biggest manga mystery, since it appears that the "Swordsmith Village" arc ends with the revelation that Nezuko cannot be destroyed in light. It makes her different from other demons. However, the series never really explained the reason Nezuko could not be killed by light, and it wasn't even mentioned found in any of the databooks, which makes one of the most remaining mysteries at the conclusion of the manga.

The Demon Slayer: Kimetsu no Yaibamanga has never clarified the reason for Nezuko's sensitivity to sunlight however, the show could have found a solution by displaying Tamayo's study of her blood during the Demon Slayer's season 3 conclusion.

The blood of Nezuko contains blue components as well, and considering that Blue Spider Lily is believed to be the reason for this, and since Blue Spider Lily has the power to rid Muzan of his vulnerability in the sun, the series may be suggesting that Nezuko's immunity stems from this Blue Spider Lily. An explanation for this may be found in the Demon Slayer databooks that could provide the explanation for one of the major plot twists in the show and also make Muzan's demise worse.

The Nezuko's Sunlight Immunity in Demon Slayer is linked with Blue Spider Lily Blue Spider Lily

Nezuko being a wolf who ate the Blue Spider Lily could explain her susceptibility to sunlight as well as the Demon Slayer: Kimetsu no Yaibahas previously justified the idea. In the second official databook The Blue Spider Lily bloomed near the home of the family Kamado, and Tanjiro was shown the place of residence by his mom. In the same book, it is stated the fact that Tanjiro was the sole child who saw them blossom however it doesn't mean that his brothers didn't see the flowers. It is possible that Nezuko might have observed and consumed this Blue Spider Lily, which could eventually lead to her being immune to the sun as the demon.

This could be the reason for one of the last developments in the Demon Slayer: Kimetsu does not Yaibamanga. Just before his demise, Muzan changes Tanjiro into a monster to attempt to keep his legacy in a state of perpetual existence. Similar to Nezuko, Tanjiro was immune to the sun, but with no justification other than Nezuko's younger brother. If Nezuko's immunity was derived through taking his Blue Spider Lily, Tanjiro's immunity may also have the same reason and adds some logic to an uninformed pair of plot surprises.

Nezuko's Sunlight Immunity Means for the Next Seasons of Demon Slayer

As Nezuko's resistance to sun becoming an open secret that is known to Muzan which creates a threat to Nezuko's back more than before. The task of protecting Nezuko against Muzan and his followers is now a major responsibility to ensure that the ultimate success for the Demon Slayers since Muzan could be able reproduce Nezuko's feat, in the event that he can get the hold of her or experiment on her, or perhaps even engulf his own body like he's accomplished with other monsters.

Nezuko is no longer an isolated incident to becoming one of the most important pieces of the chessboard which connects the Slayers and demons so valuable that it is impossible to let be taken over by the wrong people. It means taking any measure to safeguard her might be required and even if it implies that a lot of Demon Slayers in the human race must sacrifice their lives to defend her. Because she is the one Muzan has been seeking since a long time Muzan will have the courage to go the lengths of obtaining her. This means that the ultimate conflict is only in the near future.

Demon Slayer's final combat is certain to be a gruesome and bloody battle, considering that several of the strongest demons remain in the world and remain committed to Muzan. Due to the cost that's been made to take on certain of the earlier Upper Rank demons, there's most likely to be an enormous number of dead from both sides of the battle. The Hashira Training episode, which is the subject of the fourth season will revolve around getting ready for the battle.

What other mysteries should Demon Slayer's Animation address?

Demon Slayer is quite tense with its mystery that have been described in the manga series specifically. One of the most intriguing mysteries questions is why Nezuko managed to keep an element of humanity after being transformed into a demon and stop from attacking human beings, something even Lady Tamayo was unable to accomplish. There is a chance that the solution to this question is identical to that to her immunity to sunlight through exposure to Blue Spider Lily. But, this is likely to be proven by the upcoming series.

There are additional questions the anime might be able to address that the manga did not. The nature of Demon Slayer Marks, that were seen in the third season of the show, as an instance, what connection do they have with the demons? Do they have any prior knowledge of the advent of demons and weren't they just incredibly difficult to obtain? Unfortunately, they just have a few skewed rumors from the past as well as Muichiro's description of the conditions required for activation of the mark However, a more thorough explanation might be offered by someone such as Muzan and Lady Tamayo.

Another thing that is worth looking into could be Genya Shinazugawa's consumption and use of demon flesh in order to acquire the power of demonic beings. What is the way Genya initially learn about the ability? Do you know of anyone who has practiced it prior to Genya? This seems to be very beneficial to Demon Slayers however, the comic appears to suggest that the capability comes at a price. Did anyone before Genya that did this who's fate showed that it was a misstep?

Demon Slayer's Blue Spider Lily Makes Muzan's Refusal Even More Amazing

The Kamado family's knowledge of which area it was that the Blue Spider Lily bloomed can help explain why Nezuko was unable to take light, which provides more context to Muzan's misfortune. In the concluding section in the final chapter of Demon Slayer: Kimetsu no Yaiba the reader learns that the Blue Spider Lily only blooms only a handful of times per time during the daytime which means that Muzan was searching for something that was physically that was impossible to acquire. It's ironic that this is more pronounced in the event that Tanjiro and Nezuko obtained the strength Muzan desired through the human nature Muzan was averse to.

This irony reveals Muzan's most significant weakness: his total disdain towards humanity. Muzan could never appreciate the worth humanity and, unlike the other demons, Muzan carried his rage to the grave when his final plan of attack fell apart right in front of him. If Tanjiro and Nezuko have survived largely due to being able to survive because of the Blue Spider Lily, which was only available because of their humanity, the fact is promoted even more. This adds depth to the Demon Slayer series: Kimetsu No Yaiba the anime, and it goes even deeper to describe the powers of Nezuko remains a mystery that is not that is solved.
