Akaza

Akaza appears as a young man with an athletic build. After transforming into a demon, his skin turned white, and numerous blue stripes appeared on his body, reminiscent of the tattoos he had as a human. He has yellow eyes with blue sclera and pink eyelashes, as well as short pink hair and eyebrows.

He wears a short, light purple, sleeveless haori and wide white pants tied with a blue belt.

When Akaza was human, he had black hair and light blue eyes, along with unusual purple eyelashes. He had three stripes tattooed on his arms.

He wore a dark gray yukata, and in the Keizo dojo, he often wore a keikogi. He stands about 173 centimeters tall, making Akaza just over 200 years old.

Akaza is a strong, stubborn, and impulsive demon who loves to fight, especially hunting down powerful demons or Pillars. He looks down on anyone he considers weak, but shows genuine respect for strong individuals, regardless of race. He also easily angers and becomes irritated, especially by the whims of Doma and weak humans. Despite his passion for combat and stubbornness, Akaza knows when to retire.

As a human, Hakuji possessed a stubborn personality, a big heart, and resilience. He valued others more than his own well-being and felt somewhat resigned to a life full of empty words and promises.

Hakuji (Akaza, as a human) cared for his ailing father for a long time. To pay for his medicine, he went out into town to rob pickpockets. This could have led to beatings from the magistrate, but he nevertheless continued to steal until his father died. In a letter he left, he stated that he wanted Hakuji to live a full life and that he did not want to take any medicine if it was the result of stealing.

With numerous tattoos, Hakuji was eventually exiled from Edo, and it was then that he met Keizo, the owner of a dojo with no students. Keizo decided to take Hakuji under his wing so he could care for Koyuki, Keizo's ailing daughter, after her previous caretaker (her mother) drowned due to stress. Hakuji eventually cared for Koyuki until, three years later, she was well enough to stand and perform housework. He also trained as Keizo's apprentice in the Soryu style, which healed his soul.

Eventually, Keizo asked Hakuji to take over the dojo's duties and become Koyuki's husband, to which he agreed. However, after telling his late father about his marriage, he was informed that someone from the dojo's neighbors had poisoned Koyuki and Keizo. Enraged, Hakuji cold-bloodedly entered the dojo and killed everyone present with his bare hands. This incident attracted Muzan's attention, and it was then that he transformed Hakuji into a demon in an attempt to create twelve of the most powerful demons, namely the Twelve Twelve Moons.

A master of hand-to-hand combat, Akaza is a strong and skilled unarmed fighter, using close combat as his primary fighting style.

Speed. During his fight with Kyojuro Rengoku, the Flame Hashira, and in his clashes with the fighters, Akaza moved so quickly that his opponents sometimes had trouble following his every move.

Strength. Akaza can easily break an opponent's weapons, and he can also deliver blows that create craters in the ground.

Regeneration. Akaza recovered from Rengoku's wounds, survived severed limbs, and could even survive having his head severed by growing a new one.

"Deployment Technique." Allows Akaza to create shockwaves and attack from a distance while maintaining a close-combat profile. These waves ripple across space and can cause area-of-effect damage.

A sense of "killing intent." Akaza is able to pinpoint opponents based on their desire to kill—this gives him a numerical advantage in detecting those willing to fight and allows him to counter even stealthy attacks.
