Chainsaw Man: Bringing forth war. (Yoru x Denji Reader)

part 1: Thats no devil hunter..

(Yoru has 3 ''', asa has one ', denji has 2 ''. Nayuta was taken by kishibe in this AU)

A mix of 3rd and 1st person pov.

August 13th, 2024. Summer break is in the final stretch as the sky greys more often. You honestly have no clear direction in where you want to be in the future, as you've spent most of your life devil hunting for sport and a hobby. You know you could sign up for public safety, but seriously? You doesn't think they'd let a 16 year old kid in there, you'd probably get laughed at. Aww, you wanna be a devil hunter? How cute.

You're walking the path you usually take for school. Despite it still being summer break, you like to check if there's any devils around your high-school, just in case. You walk past the entrance to the school. nothing.
You walk past the field. Nothing.
You walk past the adjacent buildings. Nothing.
You do a double take of everything you walked past, maybe you just didn't see one? You dont know why you're hoping to spot a devil, as devils aren't really a good thing.

"Good. thats actually pretty good."

you turn around, walking back to the way you came. You could be more thorough and search the entire city using the transit, but would rather wait for a devil to show up on the news.
You round the corner to your apartment building, but somethings off. There's nothing wrong, but something is just inherently not right. Maybe not the building itself, but the air around it feels still. Too still, Like when all animals go silent since there's a predator nearby. Hell yeah, just what you were hoping for.

You stay silent, backing into an alley where you can transform without being seen. You wait just to make sure you aren't off your pills, maybe your brain is messing with you.

"I've been bored all day. Come on..don't tell me I'm crazy.."

A singular footstep echos throughout the empty streets. It's loud, very loud. Louder than a humans, obviously.

You put 2 fingers around the chainsaw cord, waiting. Make a move, I dare you.
You peek around the corner, looking for what's presumably a devil. You see exactly what your looking for, but its..ew. what the fuck is that?! I couldn't tell what devil that thing might be. It doesn't look strong, but..why so many arms, dude? The ripcord is pulled.

Blood spurts and stains the alley as chainsaw blades split your forearms apart down the middle, your head morphing into what appears like a chainsaw engine with jagged fangs. The sound of your body getting torn apart by your power activating also catches the attention of the devil. I mean, how wouldn't it?

Asa, fortunately and unfortunately, lives in the same apartment complex. She hears chainsaws ring and the concrete shatter below denji's feet from the weight of his sprint, the chainsaws catching Yoru's attention. Asa had given up on helping yoru find chainsaw man, as ever since she met that blonde weirdo who said he was him, she couldn't help but think that it was a lost cause due to all the fan boys claiming to be who they were idolizing. Yoru wasn't very happy about this, but it looks like she's gotten what she wanted after all.

'''Found him! Finally! Asa, get up.'''

'There's no way, right? Maybe its just people cutting down trees like yesterday.'

Asa can't even get up to look out her window before the devils blood is splattered across it, bits of bones and visceral plastered across the screen.

'..oh..'

Yoru can't contain her excitement as she hijacks Asa's body and jumps out of bed, turning one of her lamps into a spear. It'll be weak since she holds no sentimental value to yoru or asa, but it'll do.

Yoru charges and jumps, diving out the bloodied window as the glass shatters and falls onto the sidewalk. That was a good 50 foot fall, to. Yoru is met with a denji covered in the devils guts and blood, looming over and chopping the corpse up far after the devils death.

'''Waste of energy. It's already dead, idiot!'''

You turn to face the girl, all 3 chainsaw blades covered in blood, intestines draped over a shoulder like you were about to start dragging the body away.

"Wh-"
You can't get a word out before a spear is thrown at you, impaling you through the chest. The force of the throw lifts you off your feet, taking you a good 30 feet away before dipping down and pinning you to the concrete at a slanted angle.

"A devil hunter? Hey! I'm not a devil!!"

'''I'm no devil hunter, boy.'''

yoru walks over to the devils corpse, leaning foward and digging her hand into the carcass. The force of her spear throw not only sent denji a good bit away, but also caused the intestines to fall off of his shoulder. She grabs the entrails.

'''Intestinal tract whip!!'''

The intestines disconnect from the devils mutilated body, those said intestines growing serrates and becoming barbed. Yoru starts her march towards denji as he retracts a chainsaw, grabbing the spear and pulling it out of the floor with his body attached. You pull the spear out, bits of your ribs and sternum stuck to the weapon as you drop it to the sidewalk. You pull your chainsaw cord once more to extend the retracted chainsaw back out of your arm. You clashe both blades together and cause sparks to fly, yoru twirling her newly made whip.

They charge at eachother.

(Cliffhanger because I'm just like that. Also point out typos if there's any.)
