Hairo

Hairo, also known as the "Gun Demon" was a Demon exclusive to Kyojuro Rengoku's Gaiden. He also was a member of the Twelve Kizuki at his time, having held the position of Lower Rank 2 (の).

Appearance
Hairo appears as a young man with an athletic build. He has incredibly spiky black hair with two chin-length bangs framing his face. As a member of the Twelve Kizuki, he has the kanji for Lower and Two etched on his left eye.

He wears an western light suit with a black buckled belt with saggy pants and black boots. Over this, he wears a black cloak similar in appearance to a cape with protruding collars. Finally he wears a white sailor hat with a wolf emblem on its front center.

History
Not much is known about Hairo, but it is known that at some point of his life, he mastered the art of Busido but was killed by a group of marksman who insulted his swordsmanship. At some point when he became a Demon, he was nearly killed by Shinjuro Rengoku, but was either spared or escaped, and gained strength, becoming Lower Rank 2.

Personality
Hairo appears to have immense anger management issues, coming to the point of him being "suicidal": shooting himself in the head to contain it. The main cause is presumed due to mistreatment from his human life when being a samurai and/or imperial soldier. Despite his near constant anger, he has shown humbleness, seen when he venerated Kyojuro's swordsmanship before his death.

Abilities and Powers
Overall Abilities: Due to Hairo being Lower Rank 2 of the Twelve Kizuki, he is exceptionally more powerful than any average demon, his power exceeding that of the "lower" ranks Kamanue, Rui, Mukago, Wakuraba, and even rivaling Rokuro. However, due to his rank, his power should not even compare to the power of Lower Rank One, Enmu. He was able to stand his ground against Kyojuro Rengoku who was a Kinoe at the time, which is the highest non-Hashira rank of the Demon Slayer Corps.

Supernatural Abilities
Blood Demon Art:


 * Shadow Manipulation: From his blood he can create a vast number of shadows which can negate damage from physical attacks and increase his durability, absorb objects and people, and contain a suction effect that makes it difficult to escape from when in contact. Hairo can also manipulate these shadows and shape them into wolves using his Plunder Cavity technique or turn the shadows of people or objects into his Blood Demon Art, expanding the range of his attacks. His shadows also has a special property that seemingly gives even a dimensional pocket to store countless items and he can conjure these items from anywhere his shadows occupy.
 * Artillery Manipulation: Hairo's shadows also contain countless number of weapons, from pistols to bolt-rifles to shotguns and sub-machine guns, even containing a rotatory mini-gun, molotovs, dynamite and other explosives, and also a large katana. He can command these to fire at will, whether it be from his own body or from shadows he has sent out in the environment as traps, or even from the shadow wolves of his Blood Demon Art. However, these guns are real and not mystical, having a significant but limited amount of ammunition. Thus if he runs out of bullets, the guns become useless.

Miscellaneous Abilities

 * Skilled Torturer: As stated by Hairo himself, when he was human, he was extremely experienced in torturing people using a variety of methods. Hairo instinctively knew when someone was about to hit their breaking point as long as they are alive. He even has the mindset of someone who enjoys inflicting pain and suffering on others, shown when he expressed joy over wanting to torture Mitsuri Kanroji to indirectly affect Kyojuro Rengoku.

Fighting Style

 * Expert Marksman: With the nearly infinite supply of weapons at his disposal, Hairo has displayed the ability to be extremely proficient in a plethora of firearms.


 * Expert Swordsman: After depleting his supply of firearms, Hairo switches his combat stance and uses his Bushiso sword technique. His sword skill can even match the likes of Kyojuro, albeit that was when his skill wasn't as polished as when he became a Hashira.

Techniques
Plunder Cavity These techniques involve shaping his shadows into wolf-like entities and using his countless supply of weapons to attack:

 * Shadow Wolf - Hairo creates multiple shadowy wolves from his blood that emanate from his cloak, these wolves have the same suction effect as his regular shadows and thus can absorb a plethora of physical attacks and make them exceptionally hard to kill. These wolves can also conjure guns and other weapons.
 * Ravaged War Formation Wolf - With his own blood he gathers all his shadows to him and cloaks himself in them, which transforms him into a large shadowy wolf standing on its hind legs.
