Tomioka Giyu

He is an introvert

Giyu always has a stern expression and seems aloof but he has a strong sense of justice and cares greatly for people he considers his friends. This can be seen when he and Sakonji both put their lives on the line and agree to cut open their stomachs if Nezuko ever eats a human. Even though it is seen that Giyu is strong enough to single handedly kill a Lower Moon, he is awkward and keeps a distance from his fellow Demon Slayers because of an inferiority complex caused during the Final Selection. He develops survivor's guilt due to his older sister Tsutako and his dear friend Sabito who sacrificed their lives to protect Giyu and believes he doesn’t deserve to be a Pillar. Tanjiro Kamado helps him realise it’s better to cherish his life instead of wallow in grief which allows Giyu to open up to the other Demon Slayers.Giyu is an orphan whose family was killed by Demons. Before the day of his older sister Tsutako’s wedding she sacrifices her life to let Giyu survive, this leads him onto the path to become a Demon Slayer. He becomes Sakonji Urokodaki’s disciple and later holds the position of the Water Pillar. He is one of Tanjiro Kamado’s mentors and a major supporting character of Kimetsu no Yaiba (Demon Slayer). Giyu first appears to save Tanjiro Kamado from his sister Nezuko who had turned into a Demon and was on the verge of eating him. When Nezuko moves to protect his brother from Giyu rather than eating him, Giyu realises that these siblings are unique. Instead of completing his job as a Demon Slayer he decides to guide them to his former mentor Sakonji to show Tanjiro Kamado the path of a Demon Slayer.He doesn't talk much and he is a silent person. He mostly avoid people because he thinks he doesn't belong to be a hashira.Giyu and Mitsuri don't share a relationship. However, she occasionally calls him adorable.Giyu and Shinobu are both Hashira of the Demon Slayer Corps. They have opposing outward personalities and initially seem to be at odds with each other.
