Background / History

Training and Survivor’s Guilt

Giyu studied Water Breathing alongside Sabito under Sakonji Urokodaki. During their Final Selection on Mount Fujikasane, Giyu was injured and lost consciousness shortly after encountering a demon. Sabito saved the other candidates but died when his sword broke against the Hand Demon 28.

Although Giyu passed by surviving the required seven days, he regarded his survival as undeserved. He believed Sabito would have become a stronger swordsman and that he himself did not qualify to be a demon slayer, much less the Water Hashira. His repeated statement, “I’m different from you,” expressed this sense of inadequacy rather than superiority 20 28.

Meeting Lin Yoriichi

Giyu reaches the Kamado home after hearing Muzan Kibutsuji’s scream echo across Mount Kumotori. Before arriving, he sends a report through his Kasugai Crow, alerting both nearby support personnel and Headquarters. He finds blood, discarded clothing, and moving scraps of demon flesh outside the house, where Lin Yoriichi is sheltering the unconscious Kamado family 3 4.

While escorting Lin to Headquarters, Giyu responds to a distress call and rescues Murata from a slit-mouthed demon. He subsequently witnesses Lin instantly kill another demon using an unfamiliar, flame-like Breathing Style. Asked to describe Lin’s strength at the Hashira meeting, his entire assessment is simply, “Very strong” 6 7 8 10.

Kagaya Ubuyashiki later assigns Giyu and Murata to continue patrolling an area where demons have gathered. Their investigations bring them to Kyogai’s mansion and subsequently to a train associated with unexplained disappearances. They find no remaining demon traces aboard the train 12 19 20 27 30.

Returning to Final Selection

To address Giyu’s longstanding guilt, Lin brings him back to Mount Fujikasane and gives him a Disaster-Averting Mask. He reveals that the Hand Demon deliberately hunts Urokodaki’s masked students and killed Sabito 28.

Giyu confronts and kills the demon, avenging Urokodaki’s disciples. Afterward, he asks Lin to conceal the circumstances from Urokodaki, recognizing how deeply his teacher would be hurt by learning that the protective masks had identified his students to their killer 29 30.

At Headquarters, Hinaki and Kiriya Ubuyashiki formally congratulate Giyu on passing Final Selection. They repeat the induction process with a uniform, sword ore, and renewed recognition from his crow. This acknowledgment finally resolves his belief that he never deserved to join the Corps 31.

Later Campaigns

Appearance

Giyu is a black-haired swordsman with handsome, refined features and a usually wooden expression 3 6.

• Clothing: Wears a two-toned haori over his Demon Slayer Corps uniform 3 7.
• Expression: His persistent composure makes his face appear stiff or emotionless 6 27.
• Rare changes: His face twists with rage during the Hand Demon confrontation; his later attempt to smile is described as looking worse than crying 29 57.

Personality

Giyu is earnest but exceptionally blunt. His calm delivery can make ordinary questions sound commanding or dismissive, and attempts to follow communication advice often worsen the problem. Shinobu eventually concludes that his difficulty lies less in knowing how to speak than in understanding how his words affect others 3 4 27.

His apparent aloofness conceals deep insecurity and concern for others. He becomes visibly angry when a demon boasts about killing Corps swordsmen, protects Urokodaki from a painful revelation, and moves without hesitation to shield civilians from Gyutaro’s attack 7 30 60.

After his return to Mount Fujikasane, Giyu becomes less gloomy and more comfortable training beside the other Hashira. He still worries about being disliked, interpreting Tengen’s invitation as reassurance and the reaction to his awkward smile as evidence to the contrary 57.

Abilities & Skills

Water Breathing

Giyu combines rapid swordsmanship with both defensive and offensive Water Breathing techniques, including two forms of his own creation 7 29.

• Third Form: Flowing Dance — Severs Gyokko’s arms and is later used against Muzan 43 101.
• Seventh Form: Drop Ripple Thrust — A high-speed thrust used against the slit-mouthed demon, Rui, and Kokushibo. Against Kokushibo, Giyu uses it to immobilize the sword arm rather than target the neck 6 50 85.
• Eleventh Form: Dead Calm — Establishes a defensive domain intended to neutralize an opponent’s Blood Demon Art. Against the Hand Demon, Giyu advances while maintaining that domain, withering the demon’s extended arms 29.
• Twelfth Form: Torrent — A surging offensive slash developed in anger. Its debut cuts through the arms protecting the Hand Demon’s neck and completes the beheading 29 30.

Demon Slayer Mark

By the final battle, Giyu has awakened the Demon Slayer Mark 102.

• Boosts physical abilities and helps him keep pace with the fleeing, weakened Muzan 101 102.

Transparent World

Giyu learns the Transparent World through the techniques taught to the Hashira 101 102.

• Provides perception capable of seeing through an opponent’s body 101.
• Helps track Muzan despite his reduced size and use of dust clouds for concealment 102.

Bright Red Nichirin Sword

Giyu masters the heated Nichirin Blade technique before the final confrontation 101 102.

• Bright red blades hinder demon regeneration, a property Lin explains during the Hashira’s training 47.
• His precise individual awakening method is not specified in the supplied passages.

Photography

Giyu studies Kagaya’s Kodak Pocket Camera for several days until he understands its operation 107.

• Hires a professional photographer so he can also appear in the group photograph 107.
• Explains that his personal reason for learning photography is to take pictures of Shinobu 107.

Equipment / Items

• Nichirin Blade — Bears the inscription “Destroyer of Demons,” which alerts the Hand Demon to Giyu’s Hashira rank 29.
• Two-toned haori and Corps uniform — His usual clothing. He receives another uniform during his repeated induction ceremony 7 31.
• Disaster-Averting Mask — A fox-shaped mask supplied by Lin for the return to Mount Fujikasane; it draws the Hand Demon’s attention 28 29.
• Kasugai Crow — Relays emergency reports and Headquarters orders. It repeats its recognition of Giyu as its master during the renewed induction 4 30 31.
• Nichirin sword ore — Selects fresh ore during the ceremony recognizing his completed Final Selection 31.

Relationships

• Lin Yoriichi — Adviser and combat ally. Challenges Giyu’s self-doubt, encourages him to keep improving, and arranges the confrontation and ceremony that resolve his guilt 6 20 28 31.
• Sakonji Urokodaki — Water Breathing teacher. Giyu maintains contact through letters and deliberately shields him from learning why his students’ masks attracted the Hand Demon 28 29 30.
• Sabito — Fellow student whose death shapes Giyu’s survivor’s guilt. Giyu believes Sabito deserved to live and would have surpassed him 28.
• Shinobu Kocho — Fellow Hashira who regularly initiates conversations with him and tries to improve his communication. He later brings her pickled ginger on Gyomei’s advice; his declaration that he wants to photograph her makes her blush 27 56 107.
• Sanemi Shinazugawa and Obanai Iguro — Fellow Hashira frequently irritated by his remarks. Giyu’s sincere advice to Sanemi—“If you suck, practice more!”—further aggravates their difficulties 4 6 20 27.
• Murata — Fellow Corps swordsman whom Giyu rescues and later accompanies on patrol and investigation assignments 6 7 12 19 27.
• Tengen Uzui — Fellow Hashira who notices Giyu’s improved mood and invites him to the Entertainment District investigation, while continuing to tease his expressionless demeanor 57.
