Tomioka (Canon)

Giyu has a reserved personality and always wears a serious expression on his face. He is shown to have a strong sense of justice with no tolerance for those who do not know their own limitations and waste their lives. Although he held a deep hatred towards demons and never hesitated to kill one, he was able to go against the rules of the Demon Slayer Corps by protecting Nezuko Kamado upon realizing that she might be different from the rest of the demons and even agreed to sacrifice his life for the sake of her and her brother, Tanjiro Kamado by committing sepukku if the young girl ate a human. This implied that he did not completely despise demons like the rest did, and was willing to make an exception by letting them live if they did not kill or eat humans, proving in turn that he was the most pragmatic when dealing with demons instead of hating them like the rest of the hunters did.

He is someone who does not talk much and seemed to have trouble interacting with others, because of this he kept his distance from his companions [16]. This led him to have a kind of complex with what others think of him and he refused to believe that he was hated as Shinobu Kochō claimed [17]. After having the opportunity to relate to those around him, he wished to improve his relationship with the rest of the Pillars.

His distant attitude was due to the fact that he developed a strong inferiority complex since his participation in the Final Selection, which made him a more severe person; This affected him to the point of wanting to abandon his position as Water Pillar. He came to his senses after Tanjiro Kamado explained to him that he should not live with the guilt of being a survivor but that he should live for the people who sacrificed their lives for him.

Enhanced Speed: Giyu possesses a high level of speed. At times, it was imperceptible to humans and demons alike. This was demonstrated on several occasions; when he snatched Nezuko Kamado from his brother's arms, when he grabbed Inosuke Hashibira before he realized what happened, or when he cut off the head of the Lower Moon Five, Rui, in the blink of an eye. Superhuman Physical Strength: After years of training, he ended up developing superhuman physical strength. Demonstrations of his strength were shown when, for example, he managed to knock down Nezuko and Tanjiro after causing a strong gust of wind by brandishing his sword[3] or when he managed to turn his nichirin crimson red by colliding it with Sanemi's sword.

Master Swordsman: As a hunter and a pillar of the Extermination Corps, he is one of the most powerful and skilled swordsmen in the entire organization.[6] His skills as a swordsman were high enough for Akaza, the Upper Moon Three, to claim that Giyu possessed finely developed swordsmanship. Crimson Red Nichirin: During the battle against Muzan Kibutsuji, the Pillar of Wind, Sanemi Shinazugawa, had a strong clash with Giyu's Nichirin sword, causing both to temporarily turn a crimson red, granting them the ability to hinder the enhanced regeneration of demons.[8] Demon Slayer Mark (鬼き殺さつ痣あざ,, Kisatsu Aza?): During his confrontation with Akaza, he was able to awaken his Demon Slayer Mark which allowed him to enhance his physical abilities to much higher levels. His mark resembled streams of water and was located on the left side of his face.

Water Breathing (水みずの呼こ吸きゅう,, Mizu no kokyū?): This is the style he learned from his teacher, Sakonji Urokodaki. It allows him to control the oxygen in his blood, by controlling his breathing. In turn, he has the ability to increase his strength and resistance when fighting, even equaling or surpassing demons. He knew all the stances of this style, even developing his own technique, the 11th stance. Like all the pillars, Giyu was also able to maintain total concentration breathing. The stances he could perform were:

Eleventh Stance: Calm - The personal creation of the current Water Pillar, Giyu Tomioka. The user stops all bodily movement and enters a state of complete serenity, allowing them to deflect, block, and counter any incoming attacks with imperceptible speed.
