He comes

appearance:

Akaza appears as a young man with an athletic build. After his transformation into a demon, his skin turned white and he gained many blue stripes 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 light blue belt.

Personality:

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

safety features:

As the holder of the title of "Upper Moon Third", Akaza possessed immense power, being able to defeat Kyojuro Rengoku, the Flame Pillar, as well as several former Pillars, according to him. He was later able to fight on equal terms with Tanjiro and Giyu, even when they were both using their Demon Slayer Marks and Tanjiro was using the Dance of the Fire God. If he had not lost the will to continue fighting, he would have likely killed both of them. Another testament to his power is that he is the fourth most powerful Demon in the series to not have killed or eaten any women, which drastically hindered his growth as a Demon. It is safe to assume that Akaza would have been much stronger and likely of a higher rank within the ranks of the Twelve Moons Demons if he had not limited himself to killing only male humans.

Demonic abilities:

Demonic abilities Master Hand-to-Hand Combatant: Akaza is an extremely powerful and skilled unarmed fighter, using close combat as his primary fighting style. Immense Speed: Akaza is extremely fast, as shown during his fight with Kyojuro, when Tanjiro states that they were moving so fast that he could not follow their movements. Despite this, Akaza did not fight Kyojuro with a serious attitude. Immense Strength: Akaza possessed immense physical strength, as shown when he easily split Giyu's sword in half with a single side kick, despite the latter swinging his sword downwards. He could easily destroy the head of Upper Rank 2 Doma. With his Blood Demon Technique, he is capable of creating a crater on the ground by punching it. Enhanced Regeneration: Akaza had incredible regeneration. He was able to regenerate from wounds inflicted by Tanjiro and Rengoku, as well as limb loss inflicted by Giyu, without much effort. During his battle against Giyu and Tanjiro, his regeneration was further enhanced. He was able to survive even after his head was cut off, and then grow a new one. Blood Demon Technique (Kekkijutsu): Akaza has a unique ability called the "Deployment Technique" (Jutsushiki Tenkai).[2] By deploying the technique, he can use shockwave-like attacks and sense the location of his opponents by sensing their killing intent.
