Shinazugawa Sanemi

Sanemi loves his wife very much and is ready to sacrifice his life for her, no matter what it takes, he is always affectionate and caring with her.

Sanyami is a tall, muscular, and slender man. He has silver hair and dark purple eyes. Due to his frequent encounters with demons and the use of his special blood on them, his entire body is covered in jagged scars and ridges.
He wears a black version of the standard Demon Slayer uniform, unbuttoned to reveal his chest and abs, with a white long-sleeved cape over it, kanji for murder engraved on the back, white shin buckles, and tabi socks with a pair of white zori with green straps. Sanemi is sharp, hot-tempered, extroverted, and stubborn, often impulsive and quick to snap. He is often indifferent to others and can go mad very easily. The only person Sanyami showed respect to was Kakaia Ubuyashiki, and only after Sanyami realized that this man was much more than his appearance suggested. Sanyami's cold, rude, and dismissive behavior is a result of losing too many people he cared about in the past. Later, when he sees those people who have died, such as his mother, he can't help but smile at her to see her again. When Gyoza joins the Demon Slayers in search of Sanemi, Sanemi verbally abuses him, but Tanjiro can tell that Sanemi doesn't really hate him; he still has the same brotherly love for him as he did when they were kids. However, it's never expressed outwardly, as he tries to push Gyoza away from himself and the Demon Slayers to keep him safe. Sanemi's dismissive attitude towards demons.

Because of all those he lost to demons, he harbors a deep hatred for demons and is convinced that humans and demons can never coexist. When Sanemi makes a decision, it is extremely difficult to dissuade him.
