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.

Personality
Hairo appears to have immense anger management issues, coming to the point of him shooting himself in the head to contain it. The main cause is 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.

Demon Abilities
Due to Hairo being Lower Rank 2 of the Twelve Kizuki, he is exceptionally more powerful than any average demon, his power rivaling Kamanue, Rui, Mukago, Wakuraba, and maybe even Rokuro. However, due to his rank, his power shouldn't even compare to the power of Lower Rank One, Enmu. He was able to stand his ground against Kyojuro Rengoku who was a Kinoe, which is the highest non-Hashira rank of the Demon Slayer Corps.


 * Enhanced Physical Prowess: As a member of the Lower Ranks, he possesses an above average amount of Muzan's blood present in him, augmenting his physical capabilities to a superhuman level.


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


 * Katana Proficiency: 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 Rengoku, albeit that was when his skill wasn't as polished as when he became a Hashira.

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.

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

Trivia
