Demon Slayer Chapter 127

Demon Slayer Chapter 127, titled "The Rumble of Victory," brings the Swordsmith Village Arc to a dramatic close, celebrating the defeat of Upper Rank Four Hantengu and revealing a miraculous development that reshapes the future of the Demon Slayer Corps and Muzan Kibutsuji's plans. The chapter opens with a narration of Tamayo's letter to Tanjiro Kamado, expressing her gratitude for the blood samples from the Twelve Kizuki and Nezuko. Tamayo reveals she has developed an antidote allowing demons to regain consciousness, successfully testing it on one of Muzan's victims. She explains that Nezuko's blood components changed rapidly, and speculates that Nezuko hasn't regained her full consciousness because she has been prioritizing something else, hinting at her sister's impending ability to conquer the sun, a groundbreaking scientific discovery in the thrilling narrative of the Demon Slayer manga.

The scene shifts back to Nezuko and Tanjiro, with Tanjiro shaking and crying tears of pure joy as he asks Nezuko if she has finally become human again. Nezuko, still unable to speak clearly, merely echoes his words. Tanjiro realizes that despite standing unharmed in the sunlight, Nezuko still possesses her demonic fangs and eyes. Overwhelmed with disbelief and happiness, Tanjiro hugs Nezuko, tears streaming down his face, while Nezuko gently pats his head and smiles. Genya Shinazugawa, witnessing this tender moment, also smiles in relief. Tanjiro soon collapses from sheer exhaustion, and in the distance, Mitsuri Kanroji screams as the body of Hantengu, whom she was fighting, disintegrates into dust. Mitsuri falls to the ground, crying tears of joy, exclaiming that Hantengu's head must have finally been severed, celebrating their hard-won victory against the formidable Upper Rank demon.

In a chilling turn of events elsewhere, a maid and Muzan's disguised "mother" witness Muzan, in his child form, cackling gleefully before brutally obliterating his "mother's" head. The maid stares in horror as Muzan calmly declares that the Blue Spider Lily is no longer necessary. All he needs now is to find Nezuko and devour her to conquer the sun himself. As he reverts to his adult form, Muzan mercilessly murders the terrified maid as she attempts to flee. The narrative then provides a crucial flashback explaining Muzan's relentless pursuit of the Blue Spider Lily: a generous doctor had once turned him into a demon. Muzan, enraged that he would not live past twenty due to his worsening illness despite his efforts, killed the doctor. He later realized the medicine the doctor gave him had made him stronger, granting him an indestructible body but at the cost of being unable to walk in the sun. He desperately tried to recreate the medicine but lacked the Blue Spider Lily, the key ingredient, and the only person who knew its location was the doctor he had murdered. Muzan had always yearned for the perfect immortal body, and now that Nezuko has conquered the sun, all future battles will irrevocably center around her, becoming even bloodier and more desperate than before. The chapter concludes with a happy reunion hug initiated by Mitsuri, with Nezuko, Tanjiro, Muichiro, Genya, and Kotetsu grateful that no one had died, a moment of fleeting peace before the storm of the final battle against Muzan. Muichiro thanks Tanjiro for helping him recover something important, solidifying their renewed bonds of friendship and camaraderie, leaving a lasting impact on the thrilling narrative of the Demon Slayer manga.
