Sanemi Shinazugawa

Sanemi Shinazugawa is a Demon Slayer and the Wind Pillar of the Demon Slayer Corps. He is also the older brother of Genya Shinazugawa.

Appearance
Sanemi is a tall, muscular, and slender man with spiky white hair and large eyes. His face and body are covered with scars, accrued over his many years of fighting demons. He cuts his hair short somewhere in between the Functional Recovery Training Arc and the Demon Train Arc.

Personality
Sanemi is abrasive, hot-blooded, and stubborn, often times impulsive and quick to lash out. The only person he displayed reverence towards was Kagaya Ubuyashiki, and only after realizing the man was much more than his outward appearance suggested.

Sanemi's cold, rude, dismissive behavior is the result of losing too many people he cared about in the past. When Genya joins the Demon Slayers in search of Sanemi, Sanemi hurls verbal abuses at him, but Tanjiro Kamado is able to tell Sanemi didn't truly hate him; and in fact still bore the same brotherly love he had for him in childhood. This was however never expressed outwardly as he tried to push Genya away from him and the Demon Slayers so he wouldn't be exposed to danger.

Because of all those he lost to demons, he harbors a deep hatred towards demons and is convinced that humans and demons can never coexist. When Sanemi makes up his mind about something, it is extremely difficult to dissuade him&mdash; he doesn't believe Tanjiro's insistence that Nezuko Kamado doesn't eat humans, and moves to prove his own point by stabbing through the box with Nezuko inside. After riling her up, he slashes his own arm to try and bait her into attacking him due to his rare blood's effect. Even after she doesn't, and Kagaya uses this as proof Nezuko won't attack humans, Sanemi doesn't truly accept the Kamado siblings.

History
Sanemi was the eldest son of seven children and lived with both of his parents. Their father was abusive, constantly lashing out at the children and their mother until one day, he was stabbed and killed by someone with a grudge against him. Afterwards, Sanemi and Genya resolved to support their mother and family.

One day, Sanemi's mother failed to return home, so Sanemi left to search for her. At some point, he found her and realized she became a demon, but couldn't stop her from returning home and killing five of his siblings. Just before she could kill Genya, however, Sanemi tackles her through the window to the street below with a knife in hand. In the ensuing fight, she gave him the two large scars across his face, and his marechi blood&mdash;which disorients demons and makes them act intoxicated&mdash;gave him an opening to cut her down.

When Genya runs into the street to find a doctor for his grievously-injured siblings, he finds Sanemi with their mother lying dead at his feet. Panicking, and not knowing that the "wolf" that attacked them was their demonified mother, Genya screams and accuses Sanemi of murdering her. Sanemi, still in shock, became partially colorblind as their mother dissolved in the sunlight.

After that, Sanemi abandoned Genya and began to hunt demons on his own with suicidal devotion. Without knowledge of Demon Slayers or Nichirin Blades, Sanemi instead armed himself with a multitude of weapons and fought demons at night, incapacitating and capturing them until daybreak, then stringing them up to let the morning sun killed them. Despite this crude and reckless battle style, he managed to survive thanks to sheer luck and the unique aroma of his blood.

While wandering the land hunting demons, he eventually met a legitimate Demon Slayer, Masachika Kumeno, who helped him and introduced him to a proper trainer. Upon completing his training, the two of them teamed up to defeat the then-Lower Moon One of the Twelve Demon Moons. However, Kumeno lost his life in the battle, and only Sanemi was promoted to the rank of Wind Pillar. At the time of his promotion, Gyomei Himejima, Kanae Kocho, Tengen Uzui, and Giyu Tomioka were already Pillars.

Bitter over Kumeno's death, Sanemi takes his anger out on Kagaya, accusing him of happily giving orders from above while the Demon Slayers bleed and die for his cause. To his surprise, Kagaya takes the criticism gracefully before mentioning Kumeno by name; Kanae then informs him that Kagaya has memorized the names and backgrounds of every single Demon Slayer who has died since he became leader. This discovery, and reading Kumeno's will given to him by Kagaya, gives Sanemi a newfound respect for the leader of the Demon Slayer Corps. Afterwards, he is scolded by his fellow pillars Kanae, Gyomei and Tengen with Giyu just watching them from a distance.

Pillar Training Arc
Sanemi is present at the Pillar Meeting held at the Ubuyashiki Estate in the aftermath of the attack on the Swordsmith Village alongside the other remaining Pillars. When Mitsuri Kanroji attempts to explain how she got the mark he looks on at her in annoyance as she cannot properly explain the phenomenon but when Muichiro Tokito describes how he felt when the mark appeared on him Sanemi scoffs and says it is quite simple to achieve, though Giyu Tomioka rebuffs him. After it is decided that there will be a giant training session amongst all the members of the Demon Slayer Corps to help as many Demon Slayers to manifest their Demon Slayer Marks as possible, Sanemi is excited at the prospect. However, he gets into an argument with Giyu who refuses to engage with the other Pillars due to his long-standing belief that he was unworthy of his position. Sanemi is unable to read Giyu's feelings and assumes that the Water Pillar is being arrogant.

Sanemi's training session was a simple combat session where all the trainees would fight with the Wind Pillar until they were unable to continue. He conducted these sessions with great strictness and terrified Zenitsu Agatsuma to the point where the young Demon Slayer ran away from the training, only to be stopped by Tanjiro Kamado's arrival. Sanemi attempts to intimidate Tanjiro and says that he hasn't accepted the young Demon Slayer yet to which Tanjiro responds by saying that he has not accepted Sanemi either since he was the one who stabbed Nezuko Kamado and the Pillar is left impressed at Tanjiro's guts. This does not stop him from beating Tanjiro so hard that the boy receives several bruises on his face. During one of the few breaks, Tanjiro walks in on Genya Shinazugawa attempting to speak with his brother but Sanemi angrily rebukes him by saying he has no brother and to stop bothering him or else he would shred him to pieces.

He continues and says that Genya should leave the Corps as he is unable to use Breathing techniques and walks off. Genya is devastated at his brother's words and calls out to him, saying he had always wanted to apologize to him but Sanemi brushes his words aside, telling him to leave. Revealing that he overcame his lack of Breathing techniques by eating demons to fight, Sanemi is shocked and turns around, attempting to plunge his fingers into his brother's eyes but Genya is saved by intervention from Tanjiro who tackles him out of harm's way in the nick of time. Yelling at the Pillar's unseemly behaviour towards his brother and a fellow member of the Corps, Tanjiro asks if he is trying to kill Genya to which Sanemi responds that would be against the code of the Corps and hence he was aiming to leave his brother incapable of regenerating, so that he would be forced to leave the Corps. Tanjiro objects to this, saying Sanemi had no rights to do such things to his brother and gets into a fight with the Pillar which devolved into a large brawl of all the trainees attempting to stop Sanemi's rampage. This continued until the evening and Tanjiro received a scolding from the higher ups, in addition to being banned from approaching Sanemi, having to progress to Gyomei Himejima's training session instead.

Abilities and Powers
As a Pillar of the Demon Slayer Corps, Sanemi is a very powerful swordsman. According to Kokushibo, Sanemi's physical abilities and techniques have reached their peak.

Natural Abilities

 * Master Swordsman: Being a Pillar of the Demon Slayer Corps, Sanemi is one of the most powerful and skilled swordsmen in the entire organization. Sanemi's skills and sword techniques are incredibly powerful and refined, impressing even Upper Moon One Kokushibo, a Demon with hundreds of years of skill and experience behind him.


 * Intoxicant Blood (Marechi): Sanemi's blood was revealed to be one of the rarest blood types, making it incredibly intoxicating and mouth watering to demons. It is also unique due to its intense potency that the smallest whiff of his blood immediately causes demons to salivate and lose focus, as his blood was able to affect the strongest of the Upper Moon Demons, Kokushibo. So far, the only Demon who is immune to Sanemi's blood is Nezuko, due to her own strong conviction and will not to eat humans that was even further cemented and strengthen by the hypnosis planted in her brain by Sakonji Urokodaki.


 * Muscle Control: Sanemi has also shown the ability to manipulate his own muscles to close up and prevent fatal and mortal wounds from opening up and bleeding out during mid battle, as seen when he was fatally slashed and cut up across his abdomen by Kokushibo, he was still able to fight on by manipulating his own muscles to close up his wounds.


 * Crimson Red Nichirin Blade: During the battle against Kokushibo, Sanemi strikes Gyomei's spiked flail with his sword, turning both of them briefly red. Later in the fight against Muzan, Sanemi, learning from his previous encounter, forcefully clashes his sword together with Giyu's turning both of their blades temporarily red. Turning your blade red grants you the the ability to hamper the enhanced regeneration of Demons.




 * Demon Slayer Mark: Later during battle against Upper Moon One, Kokushibo, Sanemi awakened his own Mark that takes on the appearance of a single Paper Oragami Windmill with two dots on both sides on his right cheek. The mark dramatically increases his power and abilities, as seen when Sanemi was still able to fight and contend with Kokushibo on even ground, despite being grievously injured and slashed across his abdomen. This shows that his physical endurance, strength, and tolerance to pain have been dramatically increased. However, he couldn't land a significant hit on Kokushibo without assistance from Gyomei and Muichiro. In addition, he would have been put into a near-death state twice by Kokushibo if it weren't for Muichiro and Gyomei's intervention.

Quotes

 * (To Genya Shinazugawa) "You should've gotten married, had some goddamn kids, and lived until you became a goddamn old geezer. For all the times we couldn't do a thing for mom, and for all the times we couldn't do a thing for our little siblings, you should've made your goddamn wife and kids happy as they would have been. Because I would've made sure that no demon would be heading your way..."
