Yoru

Yoru, also known as the War Devil, is the deuteragonist of Chainsaw Man Part 2: Academy Saga, and a Devil that embodies the fear of war, who has taken over Asa Mitaka's body. She is a member of the Four Horsemen of the Apocalypse.

Following her taking over Mitaka's body, Yoru sets out to locate Chainsaw Man, who secretly attends the Fourth East High School with them. She also coerces Asa into looking for a target to seduce and turn into a weapon. They choose Denji; however, they eventually fail and lose their memories. After a meeting with Kiga she becomes a secret member of the Chainsaw Man Church.

As a Devil, Yoru cannot make contracts. However, she still has all the other standard Devil abilities, such as reviving in Hell after being killed, restoring her health by consuming blood, fear empowerment and enhanced physical prowess.

Physical Appearance
After taking over Asa's body and occupying half of her brain, the War Devil took on her appearance, but with added facial scars across her the center of her face and left cheek, which are in the same location where Mitaka's face was slashed by the Class President. In this form, Yoru's eyes have multiple rings, similar to Makima, who was another Horseman. Her hair is also usually worn loose rather than in twin tails like Mitaka. Yoru always wears the same clothes as Asa, most commonly a school uniform.

Yoru's Devil form appears to be a small, black-feathered bird with her signature red spiral eyes.

Occasional Appearances
In Something Important to Asa, Yoru wears Asa's underclothes after transforming them into a sword to defeat the Justice Devil.

In Endless Aquarium, Yoru wears Asa's date outfit while she throws the Aquarium Spear at the newly reincarnated Eternity Devil.

In Thief!, Yoru is put under the control of Nayuta, and is forced to act like a dog.

Powers & Abilities
War Devil Possession: After having her body and half of 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.

Weapons Creation
As a host of the War Devil, Asa has the power to make anything that belongs to her into a weapon. This includes both objects and living beings. In order to activate the weapon transformation, Asa must touch what belongs to her and call out it's weapon name.

So far the only types of weapons created have been either melee weapons such as swords and spears or explosives such as a hand grenade. It is unknown whether Asa can create more advanced weapons such as modern firearms.
 * 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. 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.
 * Aquarium Spear: A two-pronged spear approximately two meters long, made from the aquarium building Asa purchased for one million yen. The tips of the spear are fish shaped and the handle of the spear drips water. Once impaled into a target, the full contents of the aquarium explode out of the victims wound. This weapon is especially powerful due to the guilt Asa felt about destroying an entire aquarium, and was strong enough to instantly kill the reincarnated Eternity Devil who imprisoned her in the aquarium.
 * Super Chainsaw Man Motorcycle: A motorcycle made from the motorbike stolen from a man driving on the street. This motorcycle possesses a very large chainsaw which is positioned horizontally between the two wheels and extends for a few meters out the front.
 * Unspecifed strong weapon: Sometime after joining the Chainsaw Man Church Asa created a sword to hunt devils. The sword consists of of a black J-shapped crossguard covered in spikes and a seemingly detached levitating triangular blade. She used this weapon to kill at least 10 devils suggesting it's fairly powerful. It somewhat resembles one half of a scissor in it's apperance which could suggest it's origin.
 * Room 606 Sword: After getting her arm blown off by Yoshida, she is cornered by him and the Octopus Devil and turns her bedroom into an immensely powerful sword that is made up of things from around her room like the ceiling fan and bedposts.
 * Flesh Weapon Creation: Asa is able to make anyone she "owns", including humans, Devils and Fiends, into a variety of deadly weapons almost instantaneously simply by touching them.
 * Nail Knife: A simple dagger made from Asa's own fingernail, which violently ripped itself off. The knife is about a foot long, has a finger-shaped handle, an s-shape crossguard and a straight blade. It appears to bear no special properties much like a regular knife.
