Who Is Muzan Scared Of?

by Hazel

In the anime and manga series “Demon Slayer: Kimetsu no Yaiba,” Muzan Kibutsuji stands as the primary antagonist, a powerful demon with the ability to create other demons and control them. Despite his immense strength and near-immortality, Muzan harbors deep-seated fears that influence his actions and decisions throughout the series. This article delves into the sources of Muzan’s fear, exploring the characters and circumstances that terrify the Demon King and shedding light on the psychological and thematic implications of these fears.

Understanding Muzan Kibutsuji’s Character

Origins and Powers

Muzan Kibutsuji is the progenitor of all demons in the “Demon Slayer” universe. Born during Japan’s Heian era, Muzan was a frail human with a terminal illness. In a desperate attempt to cure him, a doctor administered a prototype medicine made from the Blue Spider Lily. While the medicine saved Muzan’s life, it also transformed him into a demon, granting him immense physical power, regenerative abilities, and near-immortality. However, it also gave him a vulnerability to sunlight, which could destroy him.


Goals and Motivations

Muzan’s primary goal is to overcome his weakness to sunlight and achieve true immortality. This ambition drives him to create and manipulate other demons, using them as tools to locate the elusive Blue Spider Lily and eliminate threats to his existence. His fear of death and desire for absolute power are central to his character and actions.


The Fear of the Sun

Vulnerability to Sunlight

The most immediate and pressing fear for Muzan is his vulnerability to sunlight. Unlike most demons who can be killed by decapitation with a Nichirin Sword, Muzan’s only true weakness is exposure to sunlight. This fear is deeply ingrained in him, dictating his nocturnal lifestyle and relentless quest for the Blue Spider Lily, which he believes will grant him immunity to sunlight.


Implications for Survival

Muzan’s fear of the sun influences his strategies and actions. He operates primarily at night and avoids direct confrontations during the day. This fear also drives his urgency in creating powerful subordinates to execute his plans and protect him from demon slayers who might force him into the sunlight.


Yoriichi Tsugikuni: The Unmatched Demon Slayer

Historical Context

Yoriichi Tsugikuni, a legendary demon slayer from the Sengoku era, is arguably the character Muzan fears the most. Yoriichi was a prodigious swordsman who developed the Breath of the Sun, the original breathing technique from which all other breathing styles are derived. His immense power and skill made him a formidable opponent capable of confronting Muzan directly.

The Battle with Yoriichi

During their encounter, Yoriichi nearly killed Muzan, leaving him severely injured and forcing him to retreat. This battle instilled a profound fear in Muzan, as Yoriichi was the only warrior who ever came close to ending his life. The trauma of this near-death experience haunts Muzan, shaping his perception of the demon slayers and their potential to threaten his existence.

Yoriichi’s Legacy

Even after Yoriichi’s death, his legacy continues to terrify Muzan. The Breath of the Sun technique, passed down through generations, represents a direct threat to Muzan. The Demon King goes to great lengths to eradicate anyone who possesses or could learn this technique, demonstrating his lingering fear of Yoriichi’s enduring influence.

The Kamado Family: Inheritors of Yoriichi’s Will

Tanjiro Kamado

Tanjiro Kamado, the protagonist of “Demon Slayer,” becomes a significant source of fear for Muzan. As a user of the Breath of the Sun, Tanjiro embodies the legacy of Yoriichi Tsugikuni. Throughout the series, Tanjiro’s determination, growth, and mastery of the Hinokami Kagura (Dance of the Fire God) technique make him a formidable adversary. Muzan recognizes Tanjiro’s potential to wield the same power that nearly ended his life centuries ago.

Nezuko Kamado

Nezuko Kamado, Tanjiro’s sister who was transformed into a demon by Muzan, also represents a unique threat. Unlike other demons, Nezuko retains her humanity and exhibits an immunity to sunlight—a trait that Muzan desperately seeks for himself. Nezuko’s existence challenges Muzan’s understanding of demons and poses a potential solution to his greatest weakness, which he fears might slip beyond his control.

The Demon Slayer Corps

The Hashira

The Hashira, the elite warriors of the Demon Slayer Corps, are specifically trained to combat demons and protect humanity. Each Hashira possesses exceptional strength, skill, and mastery of unique breathing techniques. Their collective power and dedication to eradicating demons make them a significant threat to Muzan. Among them, Gyomei Himejima (the Stone Hashira), Sanemi Shinazugawa (the Wind Hashira), and Giyu Tomioka (the Water Hashira) stand out as particularly formidable opponents.

Organizational Strength

The Demon Slayer Corps’ organizational strength and resources enable them to conduct extensive operations against demons. Their ability to mobilize quickly, gather intelligence, and launch coordinated attacks poses a constant threat to Muzan’s plans. The Corps’ resilience and unwavering commitment to their cause further amplify Muzan’s fear of their potential to disrupt his schemes.

Fear of Betrayal and Insurrection

The Twelve Kizuki

Muzan’s inner circle of powerful demons, known as the Twelve Kizuki, serve as his enforcers and protectors. However, Muzan’s fear of betrayal within his ranks is palpable. He imposes strict control over the Twelve Kizuki, using fear and intimidation to ensure their loyalty. The potential for insurrection or betrayal within his own ranks is a constant source of anxiety for Muzan, as even his closest allies could turn against him if given the opportunity.

Demons Seeking Redemption

Demons who seek redemption or turn against Muzan further contribute to his fear of betrayal. Characters like Tamayo, a demon who opposes Muzan and works to find a cure for demonhood, exemplify this threat. Tamayo’s knowledge of Muzan’s weaknesses and her efforts to aid the Demon Slayer Corps represent a significant danger to his control and influence over the demon world.

Psychological Factors

Paranoia and Control

Muzan’s fears manifest as paranoia and an obsessive need for control. His actions are driven by a desire to eliminate any threats to his existence, whether they come from powerful adversaries, potential betrayers, or unknown variables. This paranoia shapes his relationships, strategies, and overall worldview, highlighting his deep-seated insecurities and vulnerabilities.

Fear of Mortality

Despite his near-immortality, Muzan’s fear of death remains a central psychological driver. His obsession with overcoming his vulnerability to sunlight and achieving true immortality reflects a profound fear of mortality. This fear influences his relentless pursuit of the Blue Spider Lily and his extreme measures to eliminate any potential threats to his life.

Thematic Implications

The Nature of Fear

Muzan’s fears highlight the broader theme of fear in “Demon Slayer.” The series explores how fear influences individuals’ actions and decisions, whether it be the fear of death, failure, or the unknown. Muzan’s fears, in particular, underscore the idea that even the most powerful beings are not immune to fear and its debilitating effects.

Power and Vulnerability

The contrast between Muzan’s immense power and his underlying vulnerabilities serves as a central theme. Despite his strength, Muzan’s fears reveal his fragility and the limits of his control. This theme emphasizes the idea that true power lies not in the absence of fear but in the ability to confront and overcome it.

Conclusion: The Paradox of Muzan’s Power and Fear

Muzan Kibutsuji, the Demon King of “Demon Slayer,” is a character defined by his paradoxical nature. Despite his immense power and near-immortality, he is plagued by deep-seated fears that drive his actions and shape his character. His fear of the sun, the legacy of Yoriichi Tsugikuni, the potential of the Kamado family, and the threat of betrayal all contribute to his psychological and thematic complexity.
