A member of the race known as 'Numa,' he looks like a stick figure with flesh added. Because of this, he has no hair or facial features. Instead, the kanji character '亜' is written large across his face—he was born that way. The character can distort when he is extremely embarrassed or crying.

He is an alcoholic who loves booze so much he can't live without it. He works as a local DJ and is constantly chased by track deadlines. He has a 'tofu mentality' and gets discouraged easily. About twice a week, his friends blow the roof off his house. He uses a heavy hammer-type weapon and looks cool during combat. Probably. The house where Axiz lives is called the Agu House.

He's the one who caught the cold! He pulled repeated all-nighters to meet a deadline. His immune system dropped due to fatigue, and he fell asleep in the middle of composing with his stomach exposed and no blanket.
