Asa Mitaka

"I wish... I'd tried living just a little more selfishly."

Аса Митака Asa Mitaka (アサ) is a high school student who became the host of the War Devil.

Appearance
Asa is a high school girl of average build and height. She has brown eyes and black hair that is sometimes colored with a purple tint. Her hair is just past shoulder length, and prior to her possession by the War Devil, she wore her hair in two twin tails. After becoming a fiend, her hair is worn loose. She also received multiple scars across her face, and on her left cheek, her eyes have a spiral pattern similar to Makima's.

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 just below the knee, a bow at the collar, a wide belt at the waist, and black, knee-high socks. She also wears sneakers.

Personality
Asa is initially a quiet and unsociable girl. She dislikes her classmates, frequently wishing they would drop dead and spurning any offers of friendship, and she would prefer to study over making friends. She dislikes all Devils as a result of her parents being eaten by one. Asa later realizes that she was truly jealous of her peers, and wanted to fit in with them as well. She wants to live more selfishly, and to have the things she desired, like friends and a boyfriend.

While possessed by the War Devil, Asa is much more loud, confident, and harsh, demanding that her targets die for her. She has no problems with executing the class president and her teacher Tanaka, and confidently declares her intent to defeat Chainsaw Man.

Abilities

 * Enhanced Speed: After becoming host of the War Devil, Asa`s speed is improved to the point that she is able to move very quickly, easily jumping around and dodging attacks from the contracted Class President.
 * Enhanced Strength: After becoming host of the War Devil, Asa`s strength is improved to the point that she isable to pull Tanaka's head off his shoulders and spinal cord out of his body, requiring a great deal of force, and is able to easily carry objects as big as herself with one arm over her head.
 * Flesh Weapons: As a host of the War Devil, Asa is able to use the abilities of the War Devil to manipulate the detached body parts of other people and form them into weapons. This does not appear to immediately kill the victim, as they can still scream in pain even after having their head detached from their body.
