Asa Mitaka 3D model

Asa Mitaka (三み鷹たか アサ Mitaka Asa?) is the main protagonist of the Academy Saga. She is a high school student who became the host of the War Devil, Yoru, making her the inhabitance of the War Fiend (戦せん争そうの魔ま人じん Sensō no Majin?), though she still retains her human personality when the War Fiend allows her control, making her a rare case of a living fiend host. She attends Fourth East High School with Denji.

Asa is a high school girl of average build and height. She has brown eyes that are usually pitch dark, though the irises become much brighter when Asa is surprised or shocked. Her hair is black and is sometimes colored with a purple tint. Her hair reaches the middle of her back and she wears it in two low twin tails, making it appear shorter.

She wears the same school uniform as the rest of the girls in her class. The uniform consists of a long-sleeved button up shirt worn beneath a pinafore style dress with a pleated skirt that extends below the knee, a bow at the collar, a wide belt at the waist, and black, knee-high socks. She also wears sneakers.
