Akaza

3rd upper moon Akaza looks like

As a demon, Akaza was a muscular young man with skin so light that it appeared bright greenish-white, adorned with a pattern of thick blue lines that resembled the criminal tattoos he had when he was human. The lines on his face curved across each eye from under his ears to his temples, another blue line ran from the center of his hairline to the bridge of his nose, two more lines ran down his neck, and three more branched out from his lower back to his torso. The center line went straight down from his chest to the middle of his stomach, and the other two branched out from his chest and connected to the other two lines, forming the same three-line pattern around his waist. On his arms were lines running from his shoulders to his wrists, which turned into two more lines that went around his biceps and then down to his wrists, under which you could see that each of his fingers was also dark blue with an orange nail, and his toes also had that unusual look. Akaza had short, bright pink hair that stuck out in all directions, and yellow eyes that slanted inward, with pink eyelashes and blue sclera that looked like cracked glass. The irises were engraved with the characters meaning "Third Rank". He wore little clothing, only a short, sleeveless, dark purple-pink haori, cut off at the waist, left open to reveal his chest, which was adorned with a square pattern on the back. Underneath this, he sported a pair of baggy white pants, which he rolled up just below the knee and secured with a blue rope belt at his waist. Akaza prefers to go barefoot, but wears a chain of large, round pearls on each ankle. When he was human and called Hakuji, he had the same hair, only black instead of pink, and pale blue eyes with unusual pink eyelashes. He was a very muscular man, and had three black tattoos on each of his forearms. He was wearing a dark blue-gray yukata.
