The Most Hated Demon Slayer Characters

Demon Slayer: Kimetsu no Yaiba, created by Koyoharu Gotouge, has gained immense popularity since its release. The manga series, along with its anime adaptation, has captured the hearts of millions of fans worldwide. However, like any other fandom, there are characters that some fans just can’t stand. In this article, we will delve into the most hated characters in Demon Slayer, exploring the reasons behind their unpopularity. Let’s begin our journey into the world of the most despised characters in Demon Slayer.

1. Zenitsu Agatsuma: The Whiny Thunder Breathing User

One of the most polarizing characters in Demon Slayer is Zenitsu Agatsuma. Zenitsu is introduced as a cowardly and whiny character who possesses the Thunder Breathing technique. While some fans find his comedic outbursts and exaggerated reactions amusing, others find his constant screaming and panic attacks annoying.

Furthermore, Zenitsu’s lack of self-confidence and tendency to doubt his abilities can frustrate viewers. His constant reliance on others, particularly his mentor, Jigoro Kuwajima, and his love interest, Nezuko Kamado, can make him appear weak and dependent.

Despite these criticisms, Zenitsu does have his redeeming qualities. As the series progresses, viewers witness glimpses of his bravery and determination, proving that he is more than just a one-dimensional character. Nevertheless, Zenitsu’s initial portrayal and ongoing behavior have made him one of the most disliked characters in Demon Slayer.

2. Inosuke Hashibira: The Wild Boar Masked Warrior

Another character who receives mixed reactions from fans is Inosuke Hashibira. Inosuke is introduced as a wild and aggressive warrior who wears a boar mask. His impulsive and reckless nature, combined with his lack of social skills, can make him difficult to connect with for some viewers.

One of the main reasons for Inosuke’s unpopularity is his tendency to start fights without considering the consequences. His constant need to prove himself and establish dominance often leads to unnecessary conflicts, endangering not only himself but also his allies.

Furthermore, Inosuke’s abrasive and confrontational attitude can be off-putting to some fans. His lack of respect for personal boundaries and his habit of insulting others without provocation can make it challenging to sympathize with his character.

Despite his flaws, Inosuke’s loyalty and fierce determination to protect his friends cannot be denied. Over time, his character develops and becomes more nuanced, allowing fans to appreciate his growth. However, Inosuke’s initial portrayal and ongoing behavior have contributed to his status as one of the most disliked characters in Demon Slayer.

3. Shinobu Kocho: The Poisonous Butterfly

Shinobu Kocho, the Insect Hashira, is a character who divides the Demon Slayer fandom. Known for her sweet demeanor and gentle appearance, Shinobu initially seems like a likable character. However, some fans criticize her for her deceptive nature and manipulative tendencies.

Shinobu’s use of poison as a weapon is a point of contention for many viewers. While she claims to kill demons without causing unnecessary suffering, her methods can be seen as cruel and inhumane. Some fans argue that her poison-infused attacks do not align with the values of compassion and mercy that Demon Slayer promotes.

In addition, Shinobu’s manipulative behavior towards Nezuko Kamado can be off-putting to some fans. She uses Nezuko’s emotions and vulnerability to further her own agenda, which can be seen as exploitative and morally questionable.

Despite the criticisms, Shinobu’s tragic backstory and her dedication to eradicating demons have garnered sympathy from other fans. Her complex personality and conflicting actions make her a character that sparks intense discussions within the Demon Slayer community.

4. Kyojuro Rengoku: The Overzealous Flame Hashira

Kyojuro Rengoku, the Flame Hashira, is a character who elicits mixed feelings among fans. Known for his unwavering determination and passionate nature, Kyojuro’s overzealous behavior can rub some viewers the wrong way.

Some fans find Kyojuro’s constant preaching about the importance of protecting the weak and upholding justice to be preachy and repetitive. His unwavering commitment to his duties as a Demon Slayer can come across as self-righteous and fanatical to certain viewers.

Furthermore, Kyojuro’s lack of depth and character development, compared to other prominent characters in the series, has been a point of criticism. Some fans argue that his story arc and personality remain relatively stagnant throughout the series, making it difficult to fully connect with his character.

Despite these criticisms, Kyojuro’s heroic sacrifice and his unwavering dedication to his beliefs have earned him the respect and admiration of many fans. His role as a mentor figure to Tanjiro Kamado further adds to his popularity within the series.

5. Muzan Kibutsuji: The Vicious Demon King

Muzan Kibutsuji, the main antagonist of Demon Slayer, is a character despised by fans for all the right reasons. As the leader of the demons and the one responsible for Tanjiro’s family’s demise, Muzan embodies cruelty and evil.

Muzan’s ruthless and merciless nature, coupled with his disregard for human life, make him the embodiment of pure malevolence. His actions throughout the series, such as killing innocent people and manipulating others for his own gain, leave no room for sympathy or redemption in the eyes of fans.

Furthermore, Muzan’s lack of complexity and depth as a character has been a point of criticism. Some fans argue that his motivations and backstory are not explored in enough detail, resulting in a one-dimensional villain.

Despite his unpopularity, Muzan’s role as the primary antagonist contributes significantly to the intensity and suspense of the series. His presence drives the narrative forward and provides the necessary conflict for the growth and development of the main characters.

6. Mitsuri Kanroji: The Love-Struck Hashira

Mitsuri Kanroji, the Love Hashira, is a character who has received mixed reactions from fans. Known for her bubbly personality and obsession with finding true love, Mitsuri’s portrayal as a lovestruck individual can be polarizing.

Some fans find Mitsuri’s constant focus on love and relationships to be shallow and detracting from her potential as a strong female character. Her actions and dialogue often revolve around her infatuation with others, which can overshadow her skills as a Demon Slayer.

Furthermore, Mitsuri’s exaggerated physical appearance, particularly her large breasts, has been a point of criticism. Some fans argue that her design perpetuates unrealistic beauty standards and objectifies her character.

Despite these criticisms, Mitsuri’s unwavering loyalty to her friends and her determination to protect others cannot be denied. Her kindness and compassion towards both humans and demons have endeared her to many fans, making her a character worthy of appreciation.

7. Kanao Tsuyuri: The Emotionless Demon Slayer

Kanao Tsuyuri, a former member of the Demon Slayer Corps, is a character who has garnered mixed reactions from fans. Initially portrayed as emotionless and devoid of personality, Kanao’s lack of development and limited screen time have contributed to her unpopularity.

Some fans argue that Kanao’s lack of emotions makes it difficult to connect with her character on a deeper level. Her stoic and reserved nature often leaves viewers wanting more insight into her thoughts and motivations.

Furthermore, Kanao’s role as a secondary character, with minimal involvement in the main plot, has been a point of criticism. Some fans believe that her potential as a compelling character has been undermined by her limited screen time and lack of character progression.

Despite these criticisms, Kanao’s impressive combat skills and her dedication to the Demon Slayer Corps have earned her admiration from some fans. Her mysterious aura and enigmatic backstory add an element of intrigue to her character.
