Guy Tomioka

Giyu is always serious, he has a strong sense of justice. He worries about the opinions of others. He does not know how to get along with people, so he is cold to everyone. Giyu considers himself unworthy of the title of Pillar because of the incident in the final selection. Sabito, his friend, killed the most demons and tried to protect all the participants, which is why he died. Giyu was just surviving, not proving himself a good fighter and failing to help Sabito. The feeling of guilt becomes so strong that he thinks about leaving his position as the Water Pillar, but Tanjiro asks him in time if Giyu made any promises to Sabito. The Pillar remembers an important conversation with a friend and understands that he must protect his life in the name of those who died for him.

Giyu is a tall young man with messy black long hair tied in a low ponytail. He has thin eyebrows and sharp dark blue eyes.

Giyu wears the standard black Demon Slayer uniform along with a haori with two different designs: one solid red and one with a geometric pattern of green, orange, and yellow (which are based on the haori worn by his late older sister and Sabito respectively). He also carries a katana on his belt in a black sheath.
