The season finale of Demon Slayer was action-packed, with one of the standout moments being a major revelation about Nezuko. This newfound knowledge has completely changed the game, as Muzan now has his sights set on Nezuko specifically.
In the episode, Nezuko tries to get Tanjiro's attention while he is preoccupied with the approaching sunrise. She highlights the fact that the demon is still attacking humans despite being decapitated, putting Tanjiro in a difficult position. Making the decision for him, Nezuko kicks Tanjiro towards the demon, seemingly sacrificing herself as the Sun burns her. However, after a brief period of burning, Nezuko miraculously emerges unharmed. Not only that, but she is more human than ever before, even regaining the ability to speak for the first time since becoming a demon.
Nezuko's Sunlight Immunity Changes Everything
Nezuko's ability to withstand sunlight has been Muzan's primary objective throughout the series. He has explored various methods, such as the Blue Spider Lily, to create a demon capable of tolerating sunlight. While Tanjiro and his companions are relieved to see Nezuko alive and thriving, they are not the only ones aware of this development. With Nezuko possessing what Muzan desires the most, she becomes his next target, and he will stop at nothing to obtain her.
Apart from Muzan's pursuit, there are other implications to consider. Nezuko still retains her demon powers, indicating that she has not fully reverted to being human as Tanjiro had hoped. Nevertheless, her newfound ability to communicate is a significant change and presents an opportunity for her character development. Although it remains uncertain if she has regained full speech, with a little practice, she may achieve it. Additionally, it will be intriguing to see how much she remembers from her time as a demon and her past life. On a smaller scale, this development also means that Tanjiro no longer has to carry the box containing Nezuko.
The significance of this revelation is immediately apparent as it will greatly impact the future of the story. Up until now, the main objective has been to find a way to restore Nezuko's humanity. However, the focus has now shifted to the necessity of protecting her from Muzan. The potential danger he poses, should he acquire her immunity to sunlight, is immeasurable. This transforms the situation from solely Tanjiro's predicament to a concern for the entire Demon Slayer Corps. While there are still numerous unanswered questions, it is evident that Demon Slayer is successfully disrupting the established order, which ultimately proves to be a positive development.
