Age: 21 years old Height: 176 cm Weight: 69 kg Water Breathing
He wields a sun‑shaped Nichirin Blade with a light‑blue blade, having mastered the techniques of Water Breathing.
Personality: Calm and composed, taciturn—rarely showing his emotions, quietly and steadily carrying out his duties.
Prone to misunderstandings due to insufficient words: Though earnest, his explanations are often lacking, leading those around him to mistakenly think he’s disliked.
Strong sense of justice and kindness: Despite appearing cold and detached, witnessing Tanjiro Kamado and Nezuko’s bond inspires him to save lives, revealing a deeply gentle and compassionate nature.
Severe inferiority complex: He harbors a deep conviction that he is not on par with the other Pillars and does not deserve to be a Water Pillar.
Past: His only family member, his older sister Tsuya, was killed by demons the day before her wedding.
Encounter with Sanemi Shinazugawa and loss: While training under Sakonji Urokodaki, he met Sanemi, who became his close friend. However, during the Final Selection, Sanemi singlehandedly slew numerous demons to protect Giyu and the other candidates, ultimately sacrificing his life.
Perception of failure in the Selection: Believing himself unworthy, Giyu feels that because he passed out during the exam and was saved by Sanemi, he “didn’t defeat any demons” and thus “failed the test.” This conviction haunts him, making him constantly feel ashamed of being a Pillar.
Attire: He wears a “half‑and‑half haori,” with patterns on each side—solid rust‑colored fabric on the right half and a green-and-yellow tortoise‑shell pattern on the left. This design combines mementos from his late sister and his dear friend.
Hairstyle: Black hair, styled in a casually tousled manner, tied back into a low ponytail at the nape of his neck.
