The following article contains spoilers for the final arc ofDemon Slayer(Infinity Castle and Sunrise Countdown).
This year will be huge forDemon Slayerfans, as the first movie of the Infinity Castle trilogy will be released soon. Every fan is eagerly awaiting to see the final battle ofDemon Slayerand learn what will happen to each of the remaining characters.
The Infinity Castle arc is the penultimate arc of the story, and it is not yet clear if the movies will also cover the final arc (Sunrise Countdown) or if it will be adapted in another format (like a final season). Either way, Nezuko fans may be disappointed with the first movie, and maybe with the whole trilogy.
Nezuko’s Role in The Infinity Castle Arc Is Disappointing
In the Infinity Castle arc, the Demon Slayers Corps invade the Infinity Castle, Muzan’s true lair. Although itincludes thrilling battles and action-packed segments, Nezuko doesn’t really play a major role in this part of the story.
In fact,she’s mostly absent from the action— many might expect Nezuko to jump into the castle with the Demon Slayers, asshe seems to be able to back them in battle, but that’s not what happens in this arc.
Since Muzan has learned that Nezuko has evolved, he’s been quite disturbed that she has resistance to the sun, a power that even he hasn’t been able to develop after all these centuries. Thus, the Demon Slayers fear thatNezuko could be captured and devoured by Muzanif she joins the team. Instead of invading the castle with them, Nezuko stays behind, protected from Muzan — they alsoexpect her to return to her human form once she takes the Tamayo’s antidote.
There May Be Some Surprises
The anime adaptation is very faithful to the manga, but they may add scenes that are not in the original manga. While it is unlikely that they will change Nezuko’s role in the story, they might add a few scenes with her to please the audience and give her some spotlight in this arc.
However, it probably wouldn’t be anything major, and fans might still feel disappointed that Nezuko, despite being a strong ally, isn’t on the spotlight in this epic part of the story. It would be cool to see her standing at Tanjiro’s side to defeat Muzan, but it would also be too risky.
The Final Arc Has A Major Plot Twist
While Nezukodoesn’t play a major role in the Infinity Castle arc, she is important in the final arc, the Sunrise Countdown arc. Muzan manages to escape the Infinity Castle before it completely collapses, and Tanjiro goes after him.
Their final battle is intense, but when Muzan realizes he is about to lose, he makes his final move andturns Tanjiro into a demon, hoping that Tanjiro will become the strongest demon ever and carry out his wish. Now all the Demon Slayers who fought alongside Tanjiro must now defeat him.
Nezuko Is Important in the Sunrise Countdown Arc
Nezuko senses that something is wrong, and she runs to the place where Tanjiro and Muzan are. While Tanjiro has turned into a demon, she is completely human again — they change places for a short while.
Nezuko then asks Tanjiro to not give up and to resist Muzan’s will — which helps him a lot to resist Muzan’s temptations. Fortunately, the Demon Slayers are able to inject Tanjiro with the antidote while he still resists becoming a demon in his mental/spiritual reality.
Humans are to be protected and saved… I will never hurt them.
— Nezuko Kamado
While those who were expecting Nezuko to play a major role in the battles may be disappointed, she is present in the story in a different way, mainly through her connection to the other characters, and she playsan important role in preventingTanjiro from becoming a demon. Ifthe trilogy fully adapts the Final Arc, she will probably get more screen time in the third movie.
Since the movie will be out in Japan a few months before the international release, spoilers will likely emerge in Japanese circles before the movie hits theaters internationally. Those who want to avoid spoilers should be careful in order not to accidentally stumble upon unwanted information.
