1. Nezuko
It would be a huge oversight to exclude Kamado Nezuko from this list. Nezuko is Tanjiro’s younger sister and one of the two surviving members of the Kamado family after the devastating attack by the demon lord Muzan. However, Nezuko herself was turned into a demon.
Nezuko’s appearance is absolutely adorable, featuring long, curly black hair, a distinctive kimono, and a bamboo tube held in her mouth. With such a cute and endearing look, it’s no surprise that the villagers she lived with saw her as a beauty, according to Tanjiro. Additionally, Nezuko has become one of the major fan attractions in Kimetsu no Yaiba, with many viewers deciding to watch the series after seeing her incredibly cute design.
Nezuko is known for her kind-hearted, sincere, and caring nature, always looking out for those around her. She is willing to sacrifice herself to protect her friends, companions, and loved ones. Even after becoming a demon and losing most of her memories, she still holds onto the precious recollections of her family and the happy times spent with them.
As a demon, Nezuko possesses the ability to alter her body size, regenerate her energy while sleeping without needing blood or human flesh, enhance her strength, and wield extraordinary physical abilities. She can regenerate rapidly, has immense physical strength, and even resists sunlight.


2. Tanjiro
The main protagonist of Demon Slayer, Tanjiro, is a Kanoe-ranked swordsman in the Demon Slayer Corps. Before joining the Corps, Tanjiro’s family was slaughtered by the demon lord Muzan, and while his younger sister survived, she was turned into a demon. This tragedy drove Tanjiro to join the Demon Slayer Corps with the sole mission of saving his sister: "I will definitely save you, Nezuko."
Tanjiro is characterized by his tanned skin, athletic build, dark red-brown hair, and a scar across his forehead. His personality is often described as "kind-hearted, with a gentle gaze." Tanjiro never wavers in the face of challenges, always showing a strong determination to overcome them. One of the clearest examples of this is his unwavering commitment to turning his sister Nezuko back into a human. Tanjiro is also a true protector, always ready to defend his friends from danger.
Tanjiro is one of the most powerful swordsmen in Demon Slayer, known for his unique techniques, including the "Water Breathing" and "Hinokami Kagura" (Dance of the Fire God). At one point in the series, Tanjiro was transformed into a demon himself, but even under Muzan’s control, he never harmed his sister Nezuko. The strong bond between Tanjiro and Nezuko, along with his unyielding spirit to fight and restore her humanity, has made Tanjiro a beloved character among fans.


3. Rengoku
Rengoku (also known as the Flame Hashira) is renowned for his famous quote: "Growing old and dying – that's the beauty of a fleeting existence known as humanity. Because they grow old, because they die, they are beautiful, extraordinary, and precious." He is considered one of the most powerful swordsmen in the Demon Slayer Corps.
Rengoku is tall and imposing, with bright golden hair tinged with red highlights, dark eyebrows, and golden eyes. As a Hashira, he takes his responsibilities seriously and always approaches his missions with unwavering commitment. His kind, cheerful, and generous nature has earned him the love and admiration of both his fellow Demon Slayers and fans of the series.
Rengoku is a respected and formidable warrior, who abides by a strict moral code instilled in him by his mother: The most important duty of those born with strength is to use that power to protect the weak.


4. Kokushibo
Kokushibo (known as Upper Rank One Kokushibo of the Twelve Kizuki) is the twin brother of the strongest swordsman in Demon Slayer, with power second only to the demon lord Muzan. Kokushibo is depicted as a tall man with long black hair and bright red eyes. He is usually seen wearing black armor and a wide-brimmed hat that obscures his face. In his human life, Kokushibo was a demon slayer named Tsukiguni Michikatsu.
Kokushibo has a reserved, humble personality with a hint of coldness, and he is not afraid to acknowledge his own failures. As the Upper Rank One Kokushibo, he is an ancient demon who has won countless battles against demon slayers and has accumulated vast combat experience. This allows Kokushibo to easily identify his enemy's weaknesses and ensures his victory. Additionally, Kokushibo is capable of analyzing his opponent's techniques through their movements and can even sense the presence of an enemy from great distances.
"Moon Breathing" is considered Kokushibo's signature swordsmanship technique, one of the deadliest and most powerful styles that evolved from Sun Breathing.
In a survey conducted by AnimeNewsNetwork to determine the most popular characters from the Twelve Kizuki in Demon Slayer, Kokushibo earned the second-highest number of votes, only behind Upper Rank Three Akaza.


5. Zenitsu
Zenitsu is a member of the Demon Slayer Corps and a companion to Tanjirou, the protagonist of Demon Slayer. Zenitsu has pale skin and eyes that shift from brown to yellow, with short hair and a somewhat sickly complexion. Before becoming a demon slayer, Zenitsu had black hair, but after being struck by lightning, it turned yellow.
Zenitsu is known for his timid nature and extremely low self-esteem. He is often overwhelmed by fear, convinced that his life will be cut short due to the dangerous and demanding nature of his work as a demon slayer. Despite his childish and anxious personality, Zenitsu becomes incredibly serious during battle. In fact, his strength and fighting spirit have allowed him to defeat an Upper Rank demon, even though he is not a Hashira.
Although Zenitsu may appear childish and constantly fearful, he remains a loyal and invaluable companion to Tanjirou, supporting him in the mission to defeat demons and restore Nezuko (Tanjirou's sister) to human form. Fans also appreciate Zenitsu's unique humor, which provides lighthearted moments in a series often filled with intense battle scenes like Demon Slayer.

Muichiro has a distinctive appearance with long black hair that gradually shifts to a mint green color at the tips, and his lifeless, vacant mint green eyes. He is often perceived as indifferent and cold, seemingly detached from the world around him. However, beneath this aloof exterior lies a brilliant Demon Slayer, possessing a small but incredibly powerful physique.
