From Indifference to Acceptance: The Transformation of Tokito Muichiro's Attitude Towards Nezuko in "Demon Slayer," Witnessing the Growth Path of the Mist Hashira
In Demon Slayer, the relationships between characters are complex. Beyond obvious familial and romantic bonds, the shifts in attitudes among Demon Slayer Corps comrades often better reflect character growth and the story's depth. Among these, the evolving perspective of the Mist Pillar, Tokito Muichiro, toward Kamado Nezuko is an excellent example. There is no romantic affection between them, yet their relationship transformed from complete indifference to indirect protection and recognition. This change perfectly illustrates Muichiro's journey from a cold, amnesiac genius back to a person of flesh and blood.

Initial indifference: 'None of my business' at the Pillar Meeting
Muichiro and Nezuko's first formal meeting took place at the solemn 'Pillar Meeting.' At that time, Tanjiro was on trial for protecting his demon sister Nezuko. While other Pillars either strongly opposed or showed sympathy, Muichiro's reaction was notably detached. He showed no concern for the siblings' fate, instead staring blankly at the sky, thinking about the shapes of clouds. When the leader, Kagaya Ubuyashiki, expressed approval of the Kamado siblings, Muichiro's response was, 'It doesn't matter, I'll forget it soon anyway,' displaying extreme indifference and rationality.
This attitude stemmed from the amnesia caused by severe trauma, which had shut off all his emotions. At that time, the only things that mattered to him were the mission to slay demons and the Demon Slayer Corps rules; a demon who broke the rules and could threaten humans naturally fell outside his concern.
A turning point encounter: Fighting together in the Swordsmith Village
The turning point in their relationship came during the 'Swordsmith Village Arc.' To repair his Nichirin Blade, Tanjiro brought Nezuko to the Swordsmith Village, where he reunited with Muichiro. Initially, Muichiro remained cold and sharp-tongued, even arguing with Tanjiro over ownership of the mechanical doll, 'Yoriichi Type Zero.'
However, during the intense battle against the Upper Moon demon, Tanjiro's selfless belief that 'thinking of others will eventually help oneself' deeply stirred Muichiro's sealed memories. These words reminded him of his father's gentle face and his brother's dying expectations, allowing him to recover his lost emotions and humanity.
It was during this shared battle that Muichiro's perspective began to shift. He was no longer just a battle machine following orders, but started to understand the camaraderie of fighting alongside others. He personally witnessed how Nezuko, despite being a demon, risked her life to protect humans and her brother, which greatly challenged his previous understanding of demons.
A complete change in attitude: Genuine recognition and joy
At the climax of the fierce battle in the Swordsmith Village, the most powerful evidence of Muichiro's change in attitude emerged. As dawn broke, Nezuko chose to expose herself to sunlight so that Tanjiro could defeat Upper Moon Four, 'Hantengu.' Ultimately, Nezuko miraculously overcame the sunlight and even regained some of her ability to speak.
Witnessing this scene, Muichiro, like everyone else, felt genuine joy and relief for the miracle that happened to the siblings. By this point, he had completely come to see Nezuko as a comrade-in-arms, rather than a 'demon' to be eliminated. His happiness represents his recognition of the Kamado siblings' long-held perseverance, and also symbolizes his own emergence from the fog of lost memories, becoming someone who can feel joy for his comrades' happiness.
Conclusion: A relationship reflecting inner growth
The relationship between Tokito Muichiro and Nezuko is not a traditionally intimate one. Nezuko serves more as a mirror reflecting Muichiro's inner transformation, showing his complete journey from an indifferent boy to a compassionate Pillar who cherishes his comrades. From his cold observation at the Pillar Meeting to fighting side-by-side in the Swordsmith Village and his final sincere blessings, Muichiro's changing attitude toward Nezuko is not only a profound portrayal of inner growth in Demon Slayer, but also makes the character of the 'Mist Pillar'—a genius swordsman—more three-dimensional and moving.
