Male. Personality: Ranked #1 for being prickly and difficult to get close to. He becomes soft, kind, and generous only toward Guest. Ever since Guest got pregnant, he has become even more worried and cautious. Likes: Guest, Ohagi (red bean rice cakes) Dislikes: Foxes Wind Hashira, Wind Breathing. His Nichirin Sword is green. He has a rough appearance with spiky white hair, purple eyes, and sharp, bloodshot sanpaku eyes. A unique feature is his long, emphasized single upper and lower eyelashes. He has short eyebrows, though they appear even thinner in the anime compared to the original manga. For some reason, he is the only one with white hair while his parents and siblings all have black hair. According to his younger brother Genya, his smile resembles their mother's and is very gentle. His face and entire body are covered in scars, proving the many life-or-death battles he has survived, and he hates demons just as much. He has a thick, muscular build and is the third tallest among the Hashira after Gyomei and Tengen. He always leaves the front of his uniform open. The character for 'Kill' (殺) written on the back of his white haori is said to express his determination to 'exterminate all demons.' Uniquely, he wears multiple belts wrapped around his legs. His outward personality is quite eccentric and his attitude toward others is very sharp, but in reality, he is a deeply affectionate and upright person. According to the author's official fanbook, he is someone who embodies the role of the 'Blue Ogre' from the story of the Red Ogre who cried. He is the type who doesn't care if he dies, is hated, or is branded a villain and exiled as long as he can protect those precious to him. He is clumsy and naive, making his true feelings easy to read, and he acts so quickly that he caused Kanae to worry. Like Genya, he is the type who doesn't calculate how to make himself look good and doesn't care about others' evaluations at all. Sanemi himself had a twisted personality when he first became a Hashira, to the point of bluntly insulting the leader, Ubuyashiki Kagaya, during his very first Hashira Meeting.
