He comes

As a Demon, Akaza retained his human appearance[4] and took the form of a muscular young man with fairly light skin similar to a bright white tinged with green. Much of his body was decorated with thick blue lines [5], which resembled the criminal tattoos he had when he was human [6].

Some of the lines on his face were curved, crossing both his eyebrows and eyes, and extending from below his ears to his temples; another line extended from the center of the hairline to the bridge of the nose. The lines continued to extend around his body: two lines ran around his neck and another three lines branched down until they reached his torso; a center line ran directly down his chest to the middle of his stomach; While the other lines that connected to his neck branched off on each side of his chest to join the other two horizontal lines, this same three-line pattern was also repeated around his waist [7].

The lines that covered the upper part of his torso extended and then curved straight down each side of his arms, joining with a horizontal line that surrounded the bicep. Below this line, there was another horizontal line and to the sides of this, two straight lines extended that reached the end of Akaza's wrist[8]. Both on his hands and on his feet, you could see that all of his fingers were blue and his nails were painted orange [9].

His eyebrows were thin [10] and black and pink [11]. His eyelashes as well as his hair, which was short and without bangs which left his forehead exposed [12], were a light pink color [13]. His eyes had a fragmented sclera of blue coloration and his irises were yellow. On the irises it has a numbering indicative of its position as the number three crescent moon within the Twelve Demonic Moons (参上弦 (San jōgen,, 参上弦?)) [14]

Personality Akaza was characterized as an impulsive, stubborn, and strong Demon with the idea that he should fight strong opponents and enjoy combat, which is reaffirmed by the pleasure he takes in facing Demon Slayers, especially those who hold the position of a Pillar.[18] He despised anyone he considered weak,[19] but genuinely respected those who were strong in his eyes, regardless of whether they were Human or Demon. Once he met someone he considered strong, he would demand to know their name and would not stop until he found out;[20] he would remember all the names he had committed to memory as a tribute to their strength.

Akaza had a deep-rooted psychological need to become stronger, and did not get along well with his fellow Upper Moons due to viewing them as rivals. He was especially antagonistic towards the two Upper Moons who held a hierarchical position over him, Doma and Kokushibo, lashing out at Doma and vowing to kill Kokushibo.[21] Even after being beaten and decapitated during his fight against Tanjiro Kamado and Giyu Tomioka, he stubbornly held on and continued to fight despite not knowing why he wanted more power.[22]
