Demon Slayer: Top 10 Most Underrated Side Characters That Deserve Spotlight

10 Sabito

Sabito is a former student of the Water Hashira Sakonji Urokodaki. He appears as a pivotal character in Tanjiro Kamado’s journey. Initially portrayed as harsh and demanding during Tanjiro’s training for the Final Selection, Sabito’s tragic backstory as an orphan raised by Urokodaki reveals his profound dedication to eradicating demons. 

Despite being killed by the hands of the Hand Demon, Sabito’s spirit continues to guide Tanjiro, notably in mastering the art of slicing a massive boulder. His posthumous influence and the revelation of his kinder nature underscore his critical role in shaping Tanjiro’s path and the series’ narrative.

Sabito is considered underrated because, despite his significant impact on Tanjiro’s development and the plot, he has a relatively brief appearance in Demon Slayer. His character is less explored than other main characters, leading to his being overlooked despite his crucial role and compelling backstory.

09 Yushiro

Yushiro was once a human under the care of Tamayo, who worked as a medical practitioner. He was transformed into a demon by her to survive a grave illness. Ever since his transformation, he has served as Tamayo’s advisor and protector, showcasing his undying loyalty and willingness to do anything to protect her, even to the point of attacking or insulting anyone threatening their bond.

Yushiro’s abilities are a mix of enhanced demon traits and his knowledge as a medical expert. He is skilled in using Blood Demon Art: Blindfold, which allows him to mask or reveal the presence of things using a paper talisman. This ability is crucial in assisting Tanjiro and others in recognizing otherwise invisible threats.

Yushiro is considered underrated among fans. Despite his crucial contributions and unique abilities, such as his Blood Demon Art and medical knowledge, his character is less deeply explored or highlighted than others.

08 Tamayo 

Tamayo is a demon and an exceptionally skilled doctor. Once a human with a family, Tamayo’s life took a tragic turn when Muzan Kibutsuji deceitfully transformed her into a demon. This led to a rampage where she killed her own family, sinking her into grief and sorrow. 

However, her indomitable spirit prevailed, and she dedicated centuries to studying demon cures and eventually became a vital ally to Tanjiro Kamado and the Demon Slayer Corps. Tamayo is often underrated despite her intelligence, gentle nature, and essential role in researching demon transformations and developing the anti-Kibutsuji drug. 

Her nuanced character and kindness, rare for a demon, and her hate for Muzan due to his monstrous deeds make her a complex figure. Yet, she does not receive enough spotlight due to the series’ focus on more dynamic battles and frontline characters, leading to her significant contributions being overshadowed.

07 Sakonji Urokodaki

Sakonji Urokodaki is known as a former Water Hashira and a respected trainer of demon slayers. With his iconic tengu mask and calm, wise manners, Urokodaki plays a crucial role in the development of the main character, Tanjiro Kamado, teaching him the Water Breathing techniques

Urokodaki’s past is marked by tragedy and loss, adding depth to his character as he guides the new generation with a blend of strict discipline and deep compassion. His influence on Tanjiro and other characters profoundly shapes their paths as demon slayers.

Despite his critical role in Demon Slayer as Tanjiro’s mentor and a former Water Pillar, Sakonji Urotodaki is considered underrated primarily because his fundamental contributions occur mostly off-screen or in the background. Additionally, his willingness to commit seppuku, displaying his deep sense of responsibility and honour, adds layers to his character that might not be fully appreciated amidst the story’s more immediate and flashy elements.

06 Hotaru Haganezuka

Hotaru Haganezuka is the eccentric and passionate swordsmith known for his obsessive dedication to crafting and repairing the Nichirin Swords used by demon slayers. His intense and comedic anger towards those who damage these swords and his unpredictable personality provide a unique and humorous element to the series.

Haganezuka’s skill and commitment are crucial despite his quirks, equipping the demon slayers with the tools they need to fight. His character adds depth and colour to the series, highlighting the importance of every role in the battle against demons.

His fierce passion for the Nichirin Blades he crafts overshadows his concern for the demon slayers who wield them. The comical intensity of his character, highlighted by moments like chasing Tanjiro with knives upon learning a sword was lost, adds a unique flavour to the series. However, his behind-the-scenes contribution and brief appearances led to him being overshadowed by more central characters despite his crucial role in their battles.​

05 Kagaya Ubuyashiki

Kagaya Ubuyashiki is known respectfully as “Oyakata-sama” by his subordinates. He is the 97th Demon Slayer Corps leader and the head of the Ubuyashiki family. Kagaya is a direct descendant of the first leader of the Demon Slayer Corps and has a distant familial connection to Muzan Kibutsuji.

Kagaya doesn’t possess any fighting abilities. Instead, his strength lies in his wisdom, leadership, and strategic mind. His decisions and strategies significantly impact the direction of the Demon Slayer Corps and the battle against demons. He is deeply involved in critical events and discussions that shape the future of the demon slayers and their fight for humanity’s survival.

He is often underrated due to his serene, behind-the-scenes presence and lack of combat abilities. His significant contributions, including his strategic mind, profound wisdom, and deep understanding of the enemy, Muzan Kibutsuji, are overshadowed by more prominent, action-oriented characters. Despite his curse and deteriorating health, Ubuyashiki’s guidance and dedication remain vital to the Corps, making his understated yet crucial role in the series often underappreciated​.

04 Genya Shinazugawa

Genya Shinazugawa is a unique character in Demon Slayer due to his inability to use any Breathing technique. Instead, he compensates for this with a unique absorption ability, allowing him to battle demons effectively.
Genya comes from a tragic family background. He and his brother, Sanemi Shinazugawa (the Wind Hashira), were the only survivors after their family was slaughtered by a demon. 

This traumatic experience profoundly impacted Genya, fueling his intense hatred for demons and driving his desire to become stronger. His development from a solitary, foul-mouthed individual to someone more open to cooperation and friendly, especially during the battle against Hantengu, reflects his complex character arc. 

Genya’s initial rough and aggressive behaviour in the series and his absence of traditional Breathing Techniques might lead viewers to overlook his complexity and growth. His unapproachable attitude and lack of visually striking abilities, compared to his peers, mask the emotional depth and struggles he faces. However, as the series progresses, it becomes clear that these unique aspects contribute to underestimating his skills and the significant contributions he brings to the Demon Slayer Corps.

03 Tengen Uzui

Tengen Uzui, the Sound Hashira, is known for his flamboyant nature. He carries an impressive combination of physical attributes and unique abilities. Raised in a shinobi clan, he underwent a brutal upbringing. He later developed into one of the most talented swordsmen in the empire, wielding Nichirin Cleavers with a unique dual-wielding technique and Sound Breathing. 

His fighting techniques are powerful and tactical, like the First Form: Roar and Fifth Form: String Performance. Despite the hardships he faced, including severe injuries from battles, Tengen remains a dedicated protector against demons, often devising complex strategies and risking his life for others.​

Tengen is often underrated despite his remarkable skills and significant contributions. His creation of the Sound Breathing technique and his Shinobi training make him a formidable fighter against demons. His extravagant style and flashy behaviour might overshadow his strategic brilliance and immense physical strength, leading some to underestimate his abilities. Moreover, his profound care for his wives and the younger demon slayers under his wing adds layers to his character that are often overshadowed by his larger-than-life personality.​

02 Shinobu Kocho

Shinobu Kocho, the insect Hashira, is known for her calm and kind nature. She has mastered the insect breathing technique and has deep medical knowledge, effectively using poisons to combat demons. Her desire for a peaceful coexistence between humans and demons, alongside her personal vendetta against the Upper Moon demons, drives her actions.
Shinobu confronts the Upper Moon Two demon, Doma, in one of her significant battles. This encounter is particularly personal for Shinobu as Doma is responsible for the death of her sister, Kanae Kocho, the former Flower Hashira. Shinobu uses her unique Insect Breathing techniques, which incorporate poisons and precise movements, in her attempt to defeat Doma. The fight showcases her determination and the depth of her resolve to avenge her sister and protect others from demons. 

Shinobu Kocho is often underrated despite her critical role. She is often overlooked due to her less aggressive approach and the series’ focus on more physically powerful characters.​ Also, her significant character development and fights are in manga, which many fans have not read and are waiting for it to get animated.

01 Kanao Tsuyuri

Kanao Tsuyuri is a demon slayer and the Tsuguko, or successor, to Shinobu Kocho, the Insect Hashira. She often appears detached or emotionless due to her traumatic past. She was adopted by the Kocho sisters, Shinobu and Kanae after being found in a dire situation. Kanao uses the “Flower Breathing” technique, a derivative of the Water Breathing style

She is highly skilled and possesses incredible strength and agility. Throughout the series, Kanao undergoes significant development, growing from a passive and indecisive girl to a more assertive and emotionally open individual, mainly influenced by her interactions with the main protagonist, Tanjiro Kamado, and other characters.

Kanao Tsuyuri is often underrated despite her compelling journey and exceptional abilities. Emerging from a traumatic and abusive past, Kanao’s resilience and combat prowess, especially her mastery of the Flower Breathing technique, make her a formidable warrior. Her reserved nature and unique decision-making method of flipping a coin add depth to her character. However, her quiet nature and the series’ focus on more prominent characters led to her being overshadowed despite her significant growth and contributions.​
