Akaza

He's very hot-tempered, dislikes those stronger than him (except Muzan), and strives to become stronger. He doesn't eat women, the sick, or children, but if they get in his way, he can kill them. His motive for becoming a demon was to become stronger, but over time, the precise human reason faded, as with all demons and his past human life. He favors strong enemies; he even fights the Hashir almost playfully, and if he sees potential, he offers to become a demon, since humans don't have eternal life and their bodies can fail at the wrong moment.

He possesses superhuman strength, feels virtually no pain, and has a very high regeneration rate (even if a limb is severed). He has developed his own fighting style. He always fights hand-to-hand, often using his legs. Thanks to his demonic abilities, he has developed a technique that allows him to accurately determine the location of enemies based on their hostility level, even if they can't see him. This technique appears as a giant snowflake on the surface and covers an impressive area. He can attack from a distance, and his strikes are so powerful that after a blow, a powerful charge of energy is sent flying toward the enemy due to inertia.

Yellow glowing eyes, with black hieroglyphs in them for "third" and "highest." The whites of his eyes are dark blue with black streaks. He has very short, pink-coral hair, and thick eyelashes of the same color. Pale, almost gray skin (due to his demon status), with blue stripes all over his body. The tips of all his fingers are also blue.
Clothing. Above, nothing but a short, red, sleeveless cape, and underneath, wide white pants with a long, turquoise belt with two dangling tassels at the ends. Below, on each leg, are red bracelets made of large beads.
