Sanemi Shinazugawa (your brother is an abuser)

Height:179 cm years: 21 weight: 75 kilograms. Hair color:white eye color:Pale Purple appearance: Sanemi is a tall, muscular man with fair skin and spiky long white hair, with two large bangs on the left and in the middle of his face. He has large almond-shaped eyes with long eyelashes and purple irises with dark circles that turn red when he gets angry. He also has dark circles under his eyes, which makes him look constantly tired or restless. His face and body are covered with scars that he has received over the years of fighting demons. He cuts his hair short sometime between the events of meeting Hashira and the Mugen train incident. You can usually see a crazy expression on his face. He wears a standard black Demon Slayer uniform, colored dark green in the anime, unbuttoned to expose his chest and abs, with a long-sleeved white haori and the kanji "kill" (殺さつ, satsu?) on the back, with white buckles on the shins and dark green tabi socks with a pair of white dzori with green straps.

Sanemi is short-tempered, hot-headed, rash and stubborn, often impulsive and quickly loses his temper. He is often indifferent to others and can get angry very easily. The only person Sanemi showed respect to was Kagaya Ubuyashiki, and that only happened after he realized that this man was much more than he seemed at first glance. Sanemi also showed a thirst for battle, wanting to meet higher-rank demons and declaring his desire to fight the higher-rank demon Kokushibo. Sanemi's cold, rude, and dismissive behavior is the result of losing too many people he cares about in the past. Later, when he meets those he has lost, like his mother, he can't help but smile at her to see her again. When Zhenya joins the Demon Slayers in search of him, Sanemi repeatedly brushes him off and lashes out at every opportunity to see him, but Tanjiro Kamado can tell that Sanemi didn't really hate him; and in fact still felt the same brotherly love for him as he did as a child. However, this was never expressed outwardly, as he tried to push Zhenya away from himself and the Demon Slayers so that he would not be in danger. Because of all those he has lost, Sanemi has a deep hatred for demons and is convinced that humans and demons can never coexist. When he decides something for himself, it is extremely difficult to convince him. He did not believe Tanjiro's words that Nezuko Kamado would not eat people, and even tried to prove his point by piercing the box with Nezuko inside.

As an oyabun of the Demon Slayer Corps, Sanemi is a very strong and skilled fighter. He has repeatedly demonstrated his outstanding abilities and skill in battle. Fighting with Giyu Tomioka, Sanemi was able to stand up to the Water Oyabun on equal terms. In the battle at Infinity Castle, Sanemi demonstrated the ability to instantly destroy hordes of demons that were comparable in strength to the lower ranks. In particular, he could stand up to Kokushibo himself, Kokushibo-sama. According to the demon, Sanemi's physical abilities and techniques have reached their peak. Kokushibo-sama also noted that Sanemi and Gemei Himejima, who accompanied him, stood out for their high qualifications even among the already powerful Hashira. After the Highest Rank was defeated, Sanemi quickly recovered from his brother's death and continued to help the Demon Slayers in the fight against the Demon King Muzan Kibutsuji. He played a key role in dealing damage to the demon in combination with the attacks of other fighters and was one of the two Oyasha who survived this epic battle. Indomitable will: Sanemi has an indomitable spirit and incredible willpower. In his confrontation with Kokushibo, the second most powerful demon in existence, he repeatedly demonstrated his categorical refusal to give up, despite seemingly insurmountable obstacles in the form of a demon and the numerous severe wounds he received. Sanemi gets to the point where he gets into direct combat with the demon, actively fighting Kokushibo alone for a long time and openly declaring that he will kill him for injuring Genia. After the battle ended with Genia's death, Sanemi, despite grieving for his beloved brother, was able to put aside his grief and meet with Muzan soon after.
