Muzan Kibutsuji stands out as an irredeemable villain in the popular anime series, Demon Slayer. From the show’s inception, he is depicted as entirely self-serving and abusive, even toward those who ally with him. His ability to instill fear and exert control over even the formidable Upper Kizuki is a testament to his sinister nature, as his oppressive grip on their autonomy remains largely unchallenged. Despite appearing infrequently among his demons, his presence looms large, demonstrating a profound manipulation of power and influence.
In Demon Slayer, one demon appears to be an exception to Muzan’s authoritarian rule: Rui. Featured prominently as an antagonist in the first season, Rui may not be the most powerful demon, yet he was allowed to bend one of Muzan’s major decrees—turning humans into demons. This unique privilege, typically reserved for only the strongest within the Twelve Kizuki, suggests a complex relationship between the two characters.
The allowance for Rui to create and lead his own “family”of demons hints at a deeper understanding shared between him and Muzan. Both characters share tragic backstories as humans, and this connection may reveal a sliver of humanity beneath Muzan’s otherwise malevolent façade. His decision to permit Rui this familial bond indicates a glimpse of emotional complexity in the demon lord’s character.

Exploring Muzan’s Humanity through Rui’s Character
Muzan is frequently celebrated as one of the most intricately crafted villains in anime, and his unwavering alignment with malevolence reinforces this notion. Every action he undertakes, whether it involves verbally abusing his demon subordinates or committing atrocities against humans, amplifies his villainous reputation.
Yet, moments within Demon Slayer offer viewers glimpses of Muzan’s humanity. A pivotal instance occurs when he learns that Nezuko, a key character, can withstand sunlight. In this scene, Miyzan’s demeanor shifts, exhibiting an unexpected tranquility that contrasts sharply with his otherwise tyrannical nature.
Muzan’s relationship with Rui further illustrates this humanity. Unlike his typical interactions, Muzan treats Rui with compassion, almost as a paternal figure. While some might interpret this as mere manipulation, a closer analysis reveals a genuine connection. Rui, not known for his strength compared to the Hashira, seems to receive special treatment rooted in empathy rather than domination.
Both Rui and Muzan share parallel origins marked by suffering—sickly children driven to become demons to escape their ailments. Nevertheless, their paths diverge, as Muzan transitioned into a demon as an adult while Rui did so as a child. This nuanced difference could explain why Muzan perceives Rui as a familial figure, fostering a bond of understanding and shared experience.
Ultimately, Rui’s characteristics reflect Muzan’s influence, as he adopts violent tendencies to maintain control over his family. However, a significant distinction arises: Rui’s capacity for care contrasts starkly with Muzan’s self-interested disposition. Despite his attempts to appear empathetic, Muzan’s inherent selfishness indicates that he would prioritize his survival over Rui’s well-being.
Conclusion
The intricate relationship between Muzan and Rui provides a profound exploration of underlying humanity amidst the overwhelming darkness in Demon Slayer. Their shared backgrounds create a compelling narrative, illuminating the complexities of villainy and empathy in the realm of anime storytelling.
