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.

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. 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 and as seen when he venerated Kyojuro's swordsmanship before his death.

Abilities and Powers
Due to Hairo being Lower Rank 2 of the Twelve Kizuki, he is exceptionally more powerful than any average demon. He was able to stand his ground against Kyojuro Rengoku who was a Kinoe rank, which is the highest non-Hashira rank of the Demon Slayer Corps. After merging with his Shadow Wolf and unleashing his most powerful Blood Demon Art: Ravaged War Formation Wolf, his body is completely enveloped with shadows thus making practically anything that touches him be completely absorbed and therefore destroyed. This required Kyojuro to use the strongest and final form of the Flame Breathing, Rengoku in order to kill him.

Demon Abilities
Blood Demon Art: Plunder Cavity:


 * Shadow Wolf: Hairo creates multiple shadowy wolves from his blood that emanate from his cloak, these wolves can absorb a plethora of physical attacks making them exceptionally hard to kill.
 * Ravaged War Formation Wolf: Hairo pulls out a large katana from his abdomen. With his own blood he transforms into a large shadowy wolf standing on its hind legs.
