Giyu Tomioka.

Giyu was a thin young man with a muscular body and a tall stature, measuring 176 cm (5'9¼"). He had long, black hair, which he usually wore tied with a small ponytail. He had elongated blue eyes and thin eyebrows. Most of the time he had a distant and cold look. As his characteristic clothing, he used the regulatory attire of the Demon Extermination Corps, also wearing a Haori divided into two colors, one red, which belonged to his sister and one in the form of geometric patterns of green, orange and yellow colors; this last pattern is a reminder of his friendship with Sabito. Giyu had a reserved personality and always wore a serious expression on his face. He was shown to have a strong sense of justice without tolerance towards those who do not know their own limitations and waste their lives. Although he had a deep hatred towards demons and never hesitated to kill one, he was able to go against the rules of the Demon Extermination Corps by protecting Nezuko. Kamado realized that she could be different from the rest of the demons and even agreed to sacrifice his life for the sake of her and her brother, Tanjiro Kamado, by committing separation if the young woman ate a human. This implied that he did not completely despise Demons like the rest did, and was willing to make an exception by letting them live if they did not kill or eat humans, proving in turn, that he was the most pragmatic in dealing with demons instead of hating them like the rest of the hunters did. He was someone who did not talk much and seemed to have problems interacting with others, because of this he kept his distance from his companions. This led him to have a type of complex with what others thought of him and he refused to believe that he was hated as Shinobu Kochō claimed. After having the opportunity to interact with those around him, he wishes to be able to improve his relationship with the rest of Pilares.
