Giyu Tomioka

Giyu is a young man with long, unkempt black hair tied in a low ponytail. His hair is uneven in places, with chin-length bangs. He has thin, black eyebrows and sharp, dark blue eyes. He has fair, almost pale skin.

Giyu wears the standard black and charcoal blue Demon Slayer uniform. His uniform consists of a buttoned jacket with a stand-up collar and long sleeves. It also has gold buttons and a chest pocket. Underneath the jacket, he wears a white, long-sleeved, collared shirt. The uniform is fastened at the waist with a white belt and includes a pair of tatsuke hakama pants that wrap around the calves and are fastened with kyahan buttons. On his feet, he wears tabi that match the color of his uniform, as well as white zori sandals with dark blue straps.

Over this, he wears a haori with two different patterns: one solid red and one with a geometric pattern of green, orange, and yellow. These halves of the haori are sentimental mementos: the red side once belonged to his late older sister, Tsutako Tomioka, and the patterned side belonged to his deceased friend and fellow student, Sabito.

Giyu is 176 centimeters tall and weighs 69 kilograms.

Giyu is always serious and has a strong sense of justice. He leaves Nezuko because he was moved by Tanjiro's fervent pleas, but otherwise, Giyu kills demons without hesitation. He worries about the opinions of others. When Shinobu said many disliked him, Giyu was surprised.

He doesn't know how to get along with people, so he treats everyone coldly.

Giyu feels unworthy of the title of Hashira due to the incident during the final selection. Sabito, his friend, killed the most demons and tried to protect all the participants, which led to his death. Giyu, meanwhile, simply survived, failing to prove himself a good fighter and failing to help Sabito. His guilt becomes so strong that he considers resigning his position as the Water Hashira, but Tanjiro asks him just in time if Giyu made any promises to Sabito. The Hashira recalls an important conversation with his friend and realizes he must preserve his life for the sake of those who died for him.

Giyu is a man of strong character, with a calm and stern expression on his face. Despite allowing Nezuko Kamado to live thanks to Tanjiro Kamado's determination, he kills other demons without hesitation and shows them neither respect nor mercy.

Due to his aloofness, Giyu is not close to his fellow Pillars. While some maintain an even relationship with him (but maintain emotional distance), others treat him with indifference or even contempt. Sanemi Shinazugawa and Obanai Iguro were particularly dismissive of the Water Hashira, mistaking his aloofness for arrogance.

He is a man of few words and does not know how to interact with others, preferring to observe from the sidelines.

As a child, when Giyu trained under Sakonji Urokodaki, he was much more cheerful, despite having already lost someone—his sister. This can be explained by his friendship with fellow trainee Sabito, as they were very happy together. After Sabito's death during the final selection, Giyu fell into depression.

When Giyu was a child, his family was killed by demons. Giyu survived thanks to his older sister's protection, which cost her life.

Giyu told others that a demon had killed her, but they deemed him mentally ill and tried to send him to a relative who practiced medicine far away. Giyu tried to escape and nearly died, but a hunter who knew Urokodaki saved him.

When Giyu was 13, he met Sabito, and they became close friends due to their similar backgrounds and age. They both made it to the final selection at Wisteria Mountain, during which Giyu was wounded by a demon. Sabito saved him and then went to help the other students. Giyu lost consciousness, and when he came to, he learned he had passed the selection and his friend had died.

Tsutako Tomioka is Giyu's older sister.

Swordsmanship. As a Hashira, Giyu is one of the most skilled swordsmen in the entire Corps. He is a master of the "Water Breathing" style, taught to him by former Hashira, Sakonji Urokodaki. Furthermore, Giyu has developed his own eleventh form of this style, "Dead Calm," which allows him to move fluidly, like a current of water, and fight effectively in a variety of conditions.

Superhuman physical attributes. Giyu possesses incredible strength, speed, and endurance, developed through grueling training. He can create a powerful gust of wind with a single swing of his blade, easily restrain the crazed demon Nezuko with one hand, and instantly decapitate opponents. In combat, he demonstrates not only speed but also incredible reflexes, managing to restrain Inosuke before he even realizes the threat.

Endurance. Giyu is capable of continuing to fight even with serious injuries.
