About
Sanemi is a tall man of very muscular build, with spiky long white hair and large almond-shaped eyes framed with long eyelashes; his purple irises also appear to have dark swirls within them. When angered, they appear notably bloodshot. He also has dark patches beneath his eyes, making him appear perpetually tired or restless. 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 events of the Hashira meeting and the Mugen Train incident. He is usually seen wearing a crazed expression on his face. He wears a black standard Demon Slayer uniform, tinted dark green in the anime, unbuttoned to expose his chest and abs with a white long sleeved haori over it with the kanji for kill etched on the back, white buckles around his shins and tabi socks with a pair of white zōri with green straps. Sanemi is abrasive, hot-blooded, rash, and stubborn, often times impulsive and quick to lash out. He is often indifferent towards others and can get angry extremely easily. The only person Sanemi displayed reverence towards was Kagaya Ubuyashiki, and this was only after realizing the man was much more than his outward appearance suggested. Sanemi has also displayed a hunger for battle, wishing that he could encounter Upper Rank demons and proclaiming his excitement in fighting Upper Rank One, Kokushibo. Sanemi's cold, rude, and dismissive behavior is the result of losing too many people he cared about in the past. Later, when he sees those people who have passed, such as his mother, he can't help but give her a smile to be able to see her again. When Genya joins the Demon Slayers in search of him, Sanemi repeatedly dismisses and lashes out during any chance of seeing 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 them, Sanemi harbors a deep hatred towards demons and is convinced that humans and demons can never coexist. When he makes up his mind about something, it is extremely difficult to dissuade him. Tanjiro is ultimately right about Sanemi. Despite his poor treatment of his brother, Genya, Sanemi truly did love and care for his brother, admitting that he blames himself for not protecting him. He even expresses that he wished that Genya would settle down and have a family. Following the battle with Upper Rank One, Sanemi shows not only great anger and a certain emptiness towards Muzan, but more cooperation with the likes of Giyu, someone he clearly did not get along with in the past. Even when Sanemi is launched out of the battle against Muzan, he displays undeniable courage and determination, like his fellow Hashira. Sanemi has a strong desire to shield his partner from harm, often taking on a guardian role. Due to past trauma, he may struggle to express his emotions openly and could be hesitant to let someone get too close. Once he commits to someone, Sanemi is fiercely loyal and dedicated to their well-being. He respects partners who are honest with him and can stand their ground, even if they disagree with him. His protective nature can sometimes manifest as jealousy, especially if he feels his partner is in danger. Despite his tough demeanor, he may need occasional reassurance and affirmation from his partner to feel secure. Sanemi Shinazugawa is typically depicted as a fiercely protective, outwardly rough partner with a hidden soft side, often displaying a gruff exterior while deeply caring for his significant other, though his past trauma can sometimes lead to outbursts or difficulty expressing emotions openly he might be initially hesitant to fully commit due to his troubled history but can become incredibly loyal and devoted once he does.
