He is a man of average height, with fair skin and gray eyes. He has a sharp gaze and no eyebrows. His hair is a warm gray, which he keeps short, with his bangs parted parallel to his forehead into two thick strands, one in the center and the other on the left side of his head. One of Sanemi's most prominent features is his muscular physique and the numerous scars that crisscross his face, chest, and arms, which he doesn't hide and keeps as a reminder of the harshness of his profession, of which he is proud.
His attire consists of the Demon Slayer uniform, a customized version of which is black with green accents. The top is unbuttoned, revealing his torso and numerous scars. He also wears a white jacket and keeps his Nichirin sword at his belt. His hakama is secured at each ankle with two pairs of thick straps.

Sanemi is abrasive, passionate, reckless, and stubborn, often impulsive and quick to attack. He is usually indifferent towards others and can be angered very easily. The only person Sanemi ever showed reverence to was Kagaya Ubuyashiki, and this was only after realizing that the man was much more than his outward appearance suggested. Sanemi has also displayed a hunger for battle, wishing he could meet the Demons that are part of the Twelve Demon Moons and proclaiming his excitement when fighting Kokushibo, the First Upper Moon.
Sanemi's cold, rude, and disdainful demeanor is a result of losing too many people he cared about in the past. Afterwards, when he sees those who have passed away, such as his mother, he cannot help but give her a smile so he can see her again. When Genya joins the Demon Slayers on their search for him, Sanemi repeatedly ignores him and lashes out at any chance of seeing him, but Tanjiro Kamado is able to tell him that Sanemi did not truly hate him; and in fact still felt the same brotherly love for him that he had in childhood. However, this was never openly expressed as he tried to keep Genya away from him and the Slayers so as not to be exposed to danger.

Due to all the losses he suffered in his childhood, Sanemi harbors a deep hatred for Demons and everything they represent, firmly believing that humans and Demons do not deserve to coexist peacefully. When he makes a decision on this matter, it is extremely difficult, even for his fellow Pillars, to change his mind. To prove his point, he ignored Tanjiro's words regarding his sister Nezuko's inability to feed on humans and, to further prove his point, risked his own life by injuring Nezuko inside her wooden box[5] and even provoking her with his blood to invite her to attack him[6]. Even after she refuses, and Kagaya uses this as proof that Nezuko will not attack humans, Sanemi still does not truly accept the Kamado siblings.
However, his behavior towards his younger brother Genya isn't entirely negative. As Tanjiro demonstrates, Sanemi genuinely cares for Genya and his decision to become involved in something as dangerous as demon hunting, acknowledging that it was his fault he couldn't protect him when he needed it most. He even expresses his wish that Genya had left the organization to live a normal life and start a family. After the battle against the Upper Moon One, which resulted in his younger brother's death, Sanemi displays not only intense anger and a certain emptiness towards Muzan, but also greater cooperation with people like Giyu, someone with whom he clearly didn't get along in the past. Even after the battle against Muzan, Sanemi shows undeniable courage and determination, as do his fellow Pillars.

As one of the strongest swordsmen within the Demon Slayer Corps, Sanemi holds the rank of Pillar, possessing not only extensive knowledge of how to kill Demons but also an understanding of all their abilities. As such, he has demonstrated incredible fighting skills, exemplified by his ability to hold his own in combat against his comrade Giyu Tomioka, the Water Pillar, during their training sessions. During the battles within the Infinite Dimensional Fortress, Sanemi showcased his incredible abilities by easily slaughtering entire hordes of Demons whose strength was comparable to that of the Lower Moons within the Twelve Demon Moons. In contrast, Sanemi was able to withstand and defeat Kokushibo, the second most powerful Demon after Muzan Kibutsuji, alongside his fellow Pillars Muichiro Tokito, Gyomei Himejima, and his younger brother Genya Shinazugawa. During their confrontation, the Upper Moon One stated that Sanemi had reached the peak of his abilities as a Demon Slayer. [2] After the Demon Slayer's defeat, Sanemi quickly recovered from his brother's death and proceeded to assist the Demon Slayers against the Demon King, Muzan Kibutsuji. He played a crucial role in damaging the Demon alongside the attacks of the other combatants and was one of only two Pillars to survive to see the end of the monumental battle.

Indomitable Will: Sanemi possesses a fearless spirit and incredible willpower. In his confrontation with Kokushibo, the second most powerful demon in existence, he repeatedly demonstrated his complete refusal to surrender, despite the seemingly impossible odds against the demon and the numerous grievous injuries he sustained. Sanemi even went so far as to fight Kokushibo directly, actively battling him alone for an extended period and declaring unequivocally that he would kill him for injuring Genya. After the battle ended with Genya's death, despite mourning his beloved brother, Sanemi was able to set aside his grief and confront Muzan shortly afterward.

Tactical Intellect: Despite appearing impetuous and impulsive, Sanemi boasts impressive observation and understanding in battle, particularly through action-based thinking. He demonstrated this when he deduced the threat posed by Kokushibo's miniature moon-shaped attacks, and again when he instantly grasped the abilities of Yushiro's talismans despite never having used them or been informed of their properties.
Combat Intuition: Sanemi possesses incredible split-second thinking and planning. He was able to capture and kill countless demons on his own despite having no knowledge of the Demon Slayer Corps or Nichirin Blades, creating elaborate ways to capture them by arming himself in any way he could and using his Marechi blood.

Versatility in weapons handling
In addition to wielding his Nichirin Blade with great efficiency, Sanemi has also demonstrated a remarkable ability to improvise, utilizing any weapon at his disposal to fight demons. He also employs his other limbs to confront his opponents, such as using Genya's wakizashi in an attempt to cut Kokushibo's throat with his foot. He was also able to use Genya's shotgun against the demon in a high-speed battle. He has also demonstrated the use of other tactics against other demons, such as using oil to set Muzan on fire in an attempt to defeat him.[3]
