Asa Mitaka

Asa Mitaka (三み鷹たか アサ Mitaka Asa?) is the deuteragonist 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 Yoru allows her control, making her a rare case of a living Fiend host. Asa is a quiet and unsociable girl. She dislikes her classmates, frequently wishing they would drop dead and spurning any offers of friendship. She has a very negative outlook on the world, other humans, and Devils, and tends to assume the worst of others. She is, however, very fond of cats and would rather kill a human than a cat. Asa later admits to herself that her mean-spirited attitude towards her peers was a result of jealousy and a lack of belonging. After having her body and half of her brain taken over by the War Devil, Asa can tap into the powers of the War Devil.
