Asa Mitaka

Аса Митака

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

Asa Mitaka (アサ) is the main female 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 (の), 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.

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 she wears it in two low twin tails. When possessed by the War Devil, her appearance changes somewhat. Her hair is usually worn loose, multiple scars appear across her left cheek and nose, and 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 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 killed 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. After she becomes the host of the War Devil, gets a second chance at life, and is saved by Chainsaw Man, she is not as negative towards other humans or towards all Devils. She appreciates Chainsaw Man saving her life, but is still willing to work with Yoru in order to defeat him. Despite wanting to live more selfishly, Asa is fairly altruistic, putting herself in harm's way to save others even when she is afraid. She believes that as long as her heart is in the right place, it's okay to make mistakes.

Asa wants to help Yoru defeat Chainsaw Man as quickly as possible, since Yoru makes her and the people around her miserable. Asa would be willing to endure her situation if only she were to suffer, but refuses to drag others with her. However, she is also willing to kill a human by turning them into one of Yoru's weapons. At first she tries to compromise and suggests killing someone who "deserves it", like a criminal. But when Yoru makes it clear that Asa has to feel guilt over the person she kills, she still considers sacrificing someone whom she doesn't like, even if she doesn't think they deserve to die. Asa doesn't think of herself as a good person.

Though she considers it, Asa can't murder a person in cold blood, as she is obsessed with following the rules and doing the right thing. However, Fami believes that, like most humans, Asa can throw away her morals under the right circumstances, like starvation.

Asa suffers from low self-esteem and considers herself a clumsy individual, shown at several important points during her lifetime when she would trip and fall, most importantly when her home was destroyed by the Typhoon Devil and her mother sacrificed herself after Asa fell trying to save a cat. Asa feels guilt and incredible pain of her mother's death and the circumstances surrounding it, and greatly cherishes her memory. She can also be prone to embarrassment and becomes flustered when dealing with awkward situations, such as when she and Yoshida were partnered up together shortly after Yoru, whilst possessing her, tried to hit on him.

When Yoru is in control of her body, Yoru's personality takes over. Still, Asa can observe Yoru's actions and is usually against her more violent and head-on methods. Asa is very attached to cats, shown by her trying to save one while being attacked by the Typhoon Devil, and later saying she'd rather kill a human than a cat.

Asa can be extremely socially inept in novel situations for her, such as romance and going on a date. She believed that going to the library to learn everything about ocean facts, so she could recite them to Denji while on their date at an aquarium, would make him easily fall in love with her. Asa also believed that boys can fall for a girl easily as long as they are shown a fraction of a good time. This also shows how Asa can be falsely self-assured and overconfident in situations. When Denji showed no inclinations torwards her and ditched her to look at penguins, she was confused, believing he should have fallen for her by that point because of her plan, and refused to admit that the reason the date wasn't working was because she was boring.

Yoru
Yoru resurrected and inhabits Asa's body, turning her into the War fiend, but left half of Asa's brain intact, keeping Asa alive. With the two now sharing one body, Asa was initially overwhelmed with her situation and needed time to accept reality; she eventually agrees to help Yoru defeat Chainsaw Man under threat of permanent death and so long as she gets her body back after they defeat Chainsaw Man.

Because of Yoru's personality, Asa often gets put in awkward social situations, like asking Yoshida to be her boyfriend in an attempt to make him into a weapon. Despite her situation, Asa shows little to no fear towards Yoru. After being briefly intimidated by Yoru, Asa acts very casual towards the War Devil and isn't afraid to talk back or defy the devil if it demands something that she isn't willing to do. Because of her more passive and talk-oriented approach to conflicts, Asa commonly clashes with Yoru's methods regarding the problems they face.

Yuko
Yuko and Asa first met in their school's Devil Hunter Club tryout, when they were assigned to the same group. Asa was originally hesitant to befriend Yuko, mistaking her kindness for pity. However, Yuko explained her belief that she cares more about her heart being in the right place than whether or not her actions are a mistake. Asa quickly grew to like Yuko and said that spending time with Yuko was the most fun she had in a long time. Yuko's belief would have a heavy impact on Asa, who resolved to live her life the same and later refused to kill Yuko and turn her into a weapon for the War Devil. Even though turning Yuko into a weapon would have increased her own survival against the Bat Devil's assault, Asa instead risked her own life to save Yuko. After Yuko revealed her true colors to Asa, she felt into an almost catatonic state and refused to accept the issue, even blaming herself for Yuko's actions. Even after Yuko transformed into a monster via the Justice Devil and killed many students, Asa was still reluctant to fight her and chose to bring her back to life after killing her.

Denji
Asa and Denji are heavily intertwined, though neither fully knows it yet. Yoru, the War Devil who has taken Asa's body as a fiend, is extremely desperate to kill the Chainsaw Man in order to ignite the seeds of war in the world again, and shows an aggressive and deep loathing of him. Asa, while once holding strong negative feelings to the Chainsaw Man believing him to be a fraud and lumping him with the devil that killed her family, has become more neutral to him. After Hirofumi Yoshida introduced Asa to Denji, they immediately have conflicting attitudes and when Denji reveals himself to be the Chainsaw Man, she disbelieves him and calls him a loser. The next time they meet Denji is aggressive to her, but still accepts her offer to take him on a date.

On that date, she barrages Denji with talk of sea anemones, believing lecturing him for long periods of time will make their date interesting and make him fall in love with her. however due to her lack of dating experience and social skills with boys, Denji found her extremely boring and was willing to ditch the date to go see penguins instead of listen to her.

Supernatural Abilities
War Devil Possession: After having her body and half her brain taken over by the War Devil, while still retaining her consciousness, Asa is able to tap into the powers of the War Devil. These Powers include:

Physical Prowess:

 * 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 is able 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.
 * Enhanced Durability: After becoming host of the War Devil, Asa's durability has enhanced to the point that she survived a building collapsing on top of her with no outward injuries, though she was temporarily knocked out.

Weapons Creation:
As a host of the War Devil, Asa is able to use the abilities of the War Devil to turn anything that belongs to her into a weapon. This includes both objects and living things. She can 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. This seems to only happen when the body or body part is considered a belonging of the War Devil, either after being taken by force via being cut off and stolen, or if someone is devoted enough to the War Devil to make them its belonging.
 * Object Weapons Creation: Asa is able to turn any object that belongs to her into a weapon. An object that belongs to her can either be something she bought or took.  The guiltier Asa feels about creating the weapon, the stronger the weapon will be.  Object weapons created by Asa thus far are:
 * Super-Strong Uniform Sword: A rectangular shaped sword made from Asa’s uniform. Due to the sentimental value of it, as it was given to Asa by her late mother, the sword is extremely powerful. It was able to slice and dice Yuko in her devil form into dozens of small pieces in an instant despite the sword being knocked away. Despite its power, the sword is extremely brittle and was destroyed in the school's collapse.

Skill Set
Swordsmanship: Asa carries a katana as her weapon of choice, suggesting that she is capable of handling it.

Trivia

 * Asa's debut heavily parallels that of Denji as both her parents are deceased and she is killed in a betrayal by someone close to her, the class president, and in Denji's case the yakuza handler. She is then revived by a Devil who inhabits her body, and uses the newfound powers she gained to kill her murderer. This was likely intentional, especially since the chapter titles for Chapter 1 and Chapter 98 parallel one another.

Etymology

 * Asa's surname Mitaka means "three" (三) (mi) and "hawk/falcon" (鷹) (taka).
 * Her name, of course, alludes to the previous bird form of the devil that would eventually possess her.
