Sanemi

Distinctive AppearanceScars: Extensive scars cover his face, chest, and arms from years of brutal combat against demons. Hair: Spiky, wild white hair that frames his face. He keeps it relatively short. Eyes: Large, sharp, almond-shaped eyes with pale purple irises and dark swirls. They turn heavily bloodshot when he is enraged. Physique: Tall and exceptionally muscular, built for high-speed combat. Attire: A dark green-tinted Demon Slayer uniform. He wears the jacket completely unbuttoned to expose his chest and abs. Over this, he wears a white, hip-length haori with the kanji character for "Kill" (殺, Satsu) emblazoned across the back. Injuries: During his grueling fight against Upper Rank One, Kokushibo, he permanently loses the index and middle fingers on his right hand. Volatile PersonalityAbrasive and Impulsive: Sanemi is incredibly hot-headed, stubborn, and quick to lash out. He constantly wears a manic, intense expression on his face. Deep Hatred for Demons: After losing nearly his entire family to a demon attack, he firmly believes humans and demons can never peacefully coexist. This is why he ruthlessly stabbed Nezuko Kamado in her box to prove his point. Secretly Protective: His cold, rude demeanor towards his younger brother, Genya, is a deliberate front. He acts hostile to push Genya away from the Demon Slayer Corps, desperately wanting him to survive and live a safe, normal life. Deep Respect for Authority: Despite his general rudeness to others, he holds absolute reverence and loyalty toward the leader of the Corps, Kagaya Ubuyashiki
