Get Him to School!

Summary:

"You want me, right? To go to school?"

"Yes."

"School, as in the place I haven't been in my whole life?"

"Yes, Denji."

"Yeah no way, Aki."

"There'll... There'll be cute girls that'll, maybe... date you."

"Aki... where do I sign?"

Characters from MHA have to deal with Denji as a classmate basically. And also gotta deal with events of Chainsaw Man too while we're at it.

Notes:

Ok ok... sup! I'm a huge fan of Chainsaw Man and also like My Hero Academia as well. And it's unfortunate how little there is between when it comes to crossovers.

Solution! Make my own!

However I will not gurantee that it'll be good whatsoever. But I'll do my best!

And to give credit where it's due, my main inspirations as of right now for making this is "A Boy and His dog" and "Remnant gets a chainsaw(man)" both are great reads and I do recommend them.

(Also forgive me if the formatting is strange, I'm kinda new to AO3 as a whole)

(One last thing, I changed a few things that happen in Chainsaw Man due to either lack of memory or absolute laziness. Probably the former than the latter.)

(See the end of the work for more notes.)

Chapter Text

U.A highschool, the world's most sought after school for those who wish to be heroes. The one that only picks the best of the best. However, a boy like Denji wouldn't know crap about that.

"Well shit! This place is big!" The wide-eyed, dirty blonde cussed from amazement of the building. However he didn't exactly plan to go here to begin with.


You want me, right? To go to school?"

"Yes."

"School, as in the place I haven't been in my whole life?"

"Yes, Denji."

"Yeah no way, Aki."

"There'll... There'll be cute girls that'll, maybe... date you."

"Aki... where do I sign?"

"Nowhere, Makima's got it all covered for you to go." The pretty boy would rub his eyes from the words he used to convince the blonde.

"Lets go! I'm gonna have all the girls on me!"

Denji could already see it, all the hot babes lining up to get a taste of him.

"Hey now, it ain't gonna be that easy though. You're going to have to do some tests to even see if you're allowed to attend to begin with."

"Yeah yeah whatever dude. I'll do that then the girls will want me for sure!"

He again imagined, but stopped as he realized something.

"What about Power though?"

Denji turned to Power who lazily laid on the couch of Aki's apartment

"Yeah no. Not happening. We can barely handle her as is. I'm not going to torture the people at this school."

Aki looked at Power's direction with a stink eye before looking back at Denji.

"What's the school anyway?" Denji tilted his head slightly.

"Supposedly one filled with hero wannabe's, it's pretty famous. Although I never paid attention to it all that much. It's called U.A by the way."

"Like the guys and chicks that wear those real tight costumes or whatever around the street?"

Denji may be slightly looking back to his memories of the tights some of the girls wore.

"Yeah those idiots"


'Whoever made writing can die for all I care. Bunch of bullshit this is!'

Denji held his head in one head as he wrote with his limited vocab as well as his limited reading comprehension.

Frustrated by the questions he barely understood.

Looking up, he saw a short green haired kid walk up to the teacher and hand in his work.

'Holy shit! That kid must be smart!'

And he then saw another, then another turn in their work.

Then he turned to the time to see that there was only 5 minutes left. So in a state of panick he rushed through the paper and hurriedly turned in his work.

'Easy as pie!' He'd give a toothy grin as he walked back to his sit.

Then the lights went out with only one voice being very apparent.

"HEY LITTLE LISTENERS!"

The teacher up front yelled way too loud to be considered normal.

"OHMYGOSH! It's Present Mic! I listen to his radio show all the time!"

The green haired kid from before muttered. He wasn't very far from Denji, maybe 3-4 seats away from him. But he was weirding out everybody near him.

"Welcome to U.A where, hopefully, most of ya are able to get in and have an amazing great start in your future hero career!"

 

And then from there Denji lost the little interest that he had listening the guy speak.

Letting his mind wander to curves of women like Mt. Lady and Midnight. Heroes on which he remembered seeing on the news on TV when he wasn't killing devils or getting killed by them.

"And you! If you aren't gonna pay attention to any of this! Then you shouldn't be here!"

Some nerd pointed and yelled at him.

"Huh? Me?"

Denji just needed to make sure if it was him he was yelling at.

"Exactly my point! You should leave now!"

"Nuh uh! I'm gonna do whatever the hell I gotta do to get in the damn school!"

Denji stood up and stood his ground.

"Woah woah woah! I'm glad that the two of you are pumped to get into U.A, but there's no need for a fight!"

Present Mic intervened.

"You're absolutely right, sir! My apologies!"

The nerd sat down and so did Denji. Not without giving the guy the stink eye though.

"Anyway! The 0 Pointer doesn't give any points so you should just leave it be when ya see it!"

Mic said, though Denji didn't get it as he didn't pay much attention till now.

"Now everybody! Go to the areas that y'all've been given from those cards in front of you. Now good luck and Plus ULTRA!!"

Crickets were heard after he yelled.

"Sheesh, tough crowd."

He'd mutter to himself.


In front of some giant gates the blonde stood with the crowd.

He was tall for his age and looked really plain compared to everybody else with the age of quirks and such.

Something that Midoriya could relate to.

Till this very moment Midoriya never had a quirk, and even with it, it didn't change how he looked like at all.

Still some what short, green hair and green eyes, and those freckles. But other than that, he looked ordinary.

His nerves were, lets say, quivering. However something about the semi-formally dressed boy made him want to talk to him.

Most likely his obsession to learn about quirks.

"Um, h-hello! M-My name's Midoriya!"

He was stiff as a board, making this even more embarrassing for him.

"Oh! You're that super smart kid that turned in stuff in before everybody else!"

That's... not what he expected to hear from anybody any time soon.

"I uh guess s-so?"

"Nice to meet ya dude! Name's Denji!"

The blonde would point his thumb to himself.

Now when he thought about, Denji slightly reminded him of Kacchan a little. Although Denji was a lot more calmer so far.

Before Midoriya could utter another word, Present Mic would speak.

"Get ready kids! Your practical exam is 'bout to begin!"

"Well, um, good luck Denji."

"Good luck to ya too, man."

The giant metal gates would open in front of them, little by little showing more of the street ahead.

"Alright! In the count of 5!"

However before Mic could start counting the blonde next to Midoriya vanished.

"Hey! That's gotta be cheating!" A rando said to Mic.

 

"Ha HA! Now this kid knows a thing or two! In a real battle there ain't no count down!"

All the wannabe students took those words to heart and rushed in.


"I wonder how this year's batch of students will do!"

A small, formal suited bear thing spoke as it watched the moniters that viewed every person in the test.

"Well, you can already cut off half of these kids already."

A scarfed black haired man spoke.

"No need to be so rude Aizawa! The test barely begun."

The man stood silent as he watched along side the bear thing. However he was paying much more attention to a certain dirty blonde.

"Did someone peak your interest Aizawa?"

 

"Maybe... Nezu, tell me, has that kid even used quirk yet?"

Although he knew there was another that has yet to use their quirk, Aizawa's gut told him that this one was a stranger case.

"No not yet at least. Supposedly he needs to pull a rip cord from his chest in order to activate it."

Nezu answered.

Aizawa grunted, watching until a 2 pointer aimed at the kid.


"Jesus! What the hell is that?!" Denji stared down the bot with a confused glare, maybe he should've paid more attention... meh.

"Don't matter what you are though, cuz I'm gonna get all the babes!"

Then with his two legs, he rushed himself to the bot and pulled hard on the rip cord on his sternum.

His head aching as it's split in two by the blade as metal encased his head as well.

His arms burst with blood as more blades explode out of them. With these revving saws he slammed them in the machine with ease. Shutting it down before it could fire a missile.

"What's that 2 on ya for?"

He looked at the large number 2 that was printed on the green metal of the machine.

But before he could think on it he was quickly attacked by more of them.

"Well shit."


"Where are the robots!" Midoriya soon found out that he was the runt of the entire wannabe student body.

He had zero points and zero clue where to find them. Not to mention he didn't exactly know what to do with his new quirk.

However the loud sound of some engine didn't help either.

'An engine?'

He thought as he looked around, and sure enough he found where all that ruckus was coming from.

He saw someone with chainsaws sticking out of him rip the robots to shreds with ease.

'Just how sharp are those?'

Piles of robots would stand beneath the guy as he took a large inhale and then pushed out a large exhale from his sharp toothed mouth.

Then in further inspection, Midoriya noticed how he was dressed similarly to the blonde from earlier.

"Denji?" He called out.

"Huh? Oh! It's you again how's it going?"

The blades would melt off from his bleeding arms and his metal head turned back to normal.

"Honestly, not too good."

Midoriya rubbed his head in worry

"Why? Cuz of the robots? Actually why are there bots to begin with?"

Midoriya would give Denji a confused look.

"You're supposed to destroy them to pass the exam." Maybe he really didn't pay attention after all.

"Oh."

Looking behind him Denji saw the destruction he caused.

'Reminds me of the bastard zombies from before.' He thought.

Then a loud rumbling would shake the ground they stood on.

Making small pebbles skip as they looked up to see the massive bot behind them.

"HOLY FUCK!"

Denji really didn't wasn't going toe to toe against something that large.

He was strong, but that thing would crush him like a roach any day of the week.

But not that Midoriya guy, he bolted towards the thing without a damn care in the world.

"Dude! Get back ove--"

Before he could call'em back, Midoriya leapt through the air the very next second. Then he saw the giant dent the thing grew the very next.

"Jesus! What typa food does he eat?" Denji asked himself.

'I'm hungry'

Yawning as he thought to himself.

'I need sleep too.'

He'd walk away from the scene, stretching his arms along the way.

 

"THE TEST'S NOW OVER!" Mic yelled as the remaining machines stopped and shut down. Leaving everybody to recover.


"How'd it go?" Aki asked as he waa in the kitchen cooking them all a meal.

"It was alright, I guess." He'd lazily answered to the chef of the trio.

"Do you think you manage to pass?"

"Hell yeah!"

 

"Denji! I have a request!" A booming female voice echoed from the bathroom.

 

"Wha?! What do you want?" The blonde would shout back.

"I need that thing you humans use to clean your bottoms!"

"Ain't it already there?"

"No!"

"Ugh, fine I'll get the extras."

The boy begrudgingly stood up and went to a cupboard that was filled with extra tid bits and such.

Grabbing the paper he marched his way there with heavy footsteps.

"Here--Woah!" Unexpectedly, he was pulled by his shirt and into the restroom.

"Now, let me reiterate! I, almighty Power, have a request!"

She used her hands to add flare to herself.

"What is it?" Denji glared at her, annoyed.

"I need you to aid me in the rescue of my beloved, Meowy!"

She planted her hands on his shoulders and shook him.

"Hell no!"

"Then what about a reward for helping?"

She smirked as she removed her hands off him and placed them on her hips.

"...What would it be?"

If it was for some cash he'd be down.

"I'll let you touch my boobs."

"Where the hell is this thing?!"


During their daily devil hunting patrols, Denji would follow Power's directions. Coming across several heroes that would smile and wave at the two.

However they did get questionable glares as Denji held a hatchet. But showing them the I.D that Makima told him to use the heroes would continue to mind their business, although even then they get wary glares from those who saw the I.D and its origins.

"Wonder what scared them off?"

The boy spoke out loud which got Power to answer.

"Simple, weak humans like them just can't stand my presence."

She'd rub her nose with a smile.

The two were quiet as they sat separate from each other in the train. Until one of them spoke.

"So Power, why do you even want this cat back any way?"

"To eat him."

"Oh."

"...Tis' what I wish to do, and yet I somehow can't bear to do so. For now, I'll have him tag along till he is of no use to me."

"Do ya think everybody know's about devils?"

"In this day and age, weakling. No, at least not many of these humans do. Devils are mistaken by these quirks."

"Mhm." Denji pondered, looking back at everything that's happened to him so far.

His only true friend becoming his heart and in the same day he met Makima and was free from his father's debt. Then kicking Aki where it hurt(He liked that memory in particular) and meeting Power too.

Then this whole thing with school.

He doesn't know why he was sent there or what he'll even gain besides the ladies' attention.

But it's more than what he got in his old life, so he'll go on not caring for the reason why.

Oh! Not to forget, he's gonna be able to touch some tits soon!

The two would walk a hill that had an abandon shack right on top.

"Okay! Well I'll go ahead and get him for ya." He darted for the shack.

"Wait! I must go with you!" Power rushed ahead of him.

"Why? Didn't you say that it'd be too dangerous for ya to go since he could smell ya or something?"

He recalled the trip to the train as Power explained some of the situation.

"...I did?"

"Yeah?"

"Mhm... Slip of the tongue..."

The two stood still in front of one another.

Waiting for the other to strike. Denji decided to go for the first move by swinging the hatchet down towards her. However Power moved quickly, evading the strike. Summoning a hammer made of her blood, she quickly wacked him over the head.

Denji collapsed on to the dirt path way to the shack.

"You're a bit smarter than I thought human. However you cannot out wit me."


Denji woke up at the sudden drop as he felt the all too familiar texture of the floor.

"Here, now your end of the deal."

Power spoke to the figure that lurked in the shadow of the shack.

"Not until I get to taste the flesh of this human, fiend."

An imposing hand grabbed Denji from the floor. Clearly this guy was large in size as his hand perfectly wrapped around most of Denji's body.

Before he could cuss and curse at whoever it was, he felt his body get crushed under its hand. His own blood pouring out and dripping down.

"BLEH! What is this?! This blood is absolutely vile!" The voice boomed in fury.

"You, Blood Fiend, you will not get your animal anymore because of this!"

The voice spoke as it held a cage in front of its mouth where an echo of a meow was heard before the shadow swallowed it whole.

"Now it is your turn, fiend!"

Grabbing Power it lurched ita mouth near her, opening its mouth and she too was then swallowed whole.

"Pathetic blood that fiend gave me, however my arm has grown back. But to get rid of this aweful taste!"

The figure broke the roof of the shake, revealing what it was.

A humaniod bat that was muscaular in stature appeared as it watched the nearby city bustle in life.

"What should I eat first? A child? Maybe I'll even get a pregnant woman first."

It chuckled to itself at the thought.

Spreading its arms, he would begin to flap them, lifting himself off of the wooden ground.

Soon it would fly to the nearby city as it smiled to itself with its misangled teeth.

"Hey... you son of a bitch..."

The Bat devil heard a voice, so it turned to look back at his leg.

"Huh? You're still alive?!" Caught off guard that the human he used to replenish his arm was even breathing.

Denji took a bite outta the devil's leg which caused it to twitch in pain.

"GET. OFF. ME!"

The bat kicked him leg to get him off, but the human wouldn't let go.

In this struggle the devil would accidently slam itself into a building and leave out the other side.

Screams were heard in the street as well as in the building that had its walls caved in.

Citizens ran away as many small time heroes arrived to stop the attack.

"Must heal again!"

It would declare as he reached for the men and women in costumes before grabbing one and crushing one for their blood. Which terrified the other small time heroes enough to make them run off.

The wounds the bat suffered from the crash were now mending

"You... SON OF A BITCH!"

The bat turned to the voice, his eyes widening as it was the same human again.

"All I wanted to do..."

The annoying human would reach for whatever it was that was on his chest and scream.

"WAS TO COP A GODDAMN FEEL!"

Before he knew it the bat would feel a fist slam into his face, throwing him back into another building.

"Damn huma--Wait! You're not one of them! You're one of us!"

The bat soon threw two cars at the hybrid, dodging one and then catching the other in its arms.

In the said car, there was driver who looked absolutely horrified to say the least.

"Why are helping them?!"

"Helping?! The only damn person I'm helping is myself!"

Denji would throw the car right back at him with everything he had.

The bat moved letting the car crash down to the street behind him. Inhaling a deep breathe, it would soon exhale to release a sonic boom. Which would push Denji back.

Denji was relentless though, he got right back up and rushed to the devil.

Skipping through all the debris to reach him. Pulling the chainsaws as far as he could as he jumped into the air and stabbed the bat in the stomach.

He didn't stop there though, Denji would run his saws across its stomach and let the devils guts spill onto the floor.

He'd breathe heavily as the saws melted off his skin to show his normal features, albeit from his sharp teeth.

He'd walk into the messy gore of the Bat Devil and saw Power clutching the cage that held a pretty fat cat.

He would lift her head off the gory ground, making her eyes open.

"Ah, it seems to be you."

Denji said nothing, only pointing at her chest and squeezing his hand in the air.

"How typical of a human."

"NO! What have you done to my sugar pie!" Another voice appeared.

This time it was a gross... thing. Yikes.

"Oooo, hold on! You ain't so bad on the eyes cutie!"

The disgusting thing looked at Denji with her non-existent eyes

"How about you come with me and I'll forget all about this."

"Hell no!"

"Mhm, very well!"

Before he knew it, a tentacole slammed against his side and threw him to the side. Knocking the wind out of him.

"Mhm, what a shame, what a shame! Me and my honey both had dreams of eating all the humans we wanted and know its ruined. Now I'll be lonely in doing it myself!"

"Dreams, huh... Well, my dream's to cop a feel, but nobody cares about that!"

He got up on his two legs, closing his fists and clenching his teeth.

"...What kind of dream is that?"

The thing's mouth was now formed to one of confusion and a hint of disgust.

"How about this!"

He pulled the ripcord, however he lacked blood, earning him a very small blade to split his head.

An eye of his would slighty bulge out its socket.

"We'll have a battle of dreams! You eating every other dude here or my dream of wanting to touch some titties!"

"Aww, how adorable. But very well cutie!"

*SLAM*

Dust would pick up between the two as a figure would be in the dust.

"Do you know why it's all going to be fine?" A boisturous voice echoed in the street, "Because... I AM HERE!"

The dust would settle to show a titan of a man.

He stood with a smile as he approached the devil in front of him.

"Now villain surrender now or prepare to be beaten!" The hero spoke to the leech.

 

"I think not." It'd use its tentacole to try to stab the man, however the man himself managed to grab ahold of it.

Pulling it to throw the Leech towards him.

And with one mighty punch, send it right back to where it was. Knocking the devil out cold.

"HAHAHA!!" The man laughed at his victory before he decided to check on the two.

However was stopped.

"Alright, All Might, we'll take it from here." A stone cold voice spoke, walking ahead of hero.

"Who might you be?" All Might asked.

"We're from Public Safety. Aside from that sir, it is a honor to meet you."

"Hey... Aki, who are all these guys."

Denji loosely put together as he was practically dry when it came to his blood

"Mhm." Aki grunted

"Pick these idiots up, please." He'd rub his eyes in frustration as he ordered them.

"Will they be alright?" All Might asked, concerned.

"Yes sir, they'll just need some rest. You should go, we'll handle the mess."

"Very well." All Might left, however he felt something off.

"Wait a minute, that boy was in the practical exam!"

He was lucky to even recall him as he did sorta only pay attention to Young Midoriya after all.

"But why does he have connections to Public Safety?"


"Idiots, the two of you." Aki scolded the boy who was in a hospital bed.

"Whatever man."

"You're lucky that you're a devil hybrid, the docs were surprised that you were even awake from all that blood loss."

"Uh huh."

"Look, I don't care if you get killed okay? If anything it'll make my life a whole lot easier for me. But for some reason, Makima needs you. So I'm having to pull all the stops for this bullshit."

Denji didn't speak, as he did have something else in mind.


"Go ahead, you have earned it human!"

Power and Denji were stuck in the restroom once more. With Power presenting her breasts to the boy who was fixated.

With little hesitation he started to grope. However things would fall out of her clothes.

"How evil humans can be! You can touch them two more times!"

Power's breasts got smaller which kinda disappointed Denji.

Hey, boobs are boobs though.

He went in and groped again, getting her to moan.

Which excites the boy until he realizes that the moans were fake.

The last grope he didn't care much to register in. Power straight up left after he was done.

He looked at his hands with eyes of sheer unfulfillment.

That was all he could think of how it didn't feel like how he thought it was gonna be.

What was it that was missing?


"Makima?"

"Yes Denji?"

"Have you... Have you done something that left ya, I dunno... disappointed, I guess?"

The two spoke in Makima's office.

"Is this something to do with Power?"

She raised an eyebrow with a small knowing smile.

"Uhh... maybe."

"Well, maybe its because you didn't know her."

"Huh?"

"Mhm, as in you didn't know each and every little detail about her. What she likes, what she hates. Or maybe its because you had no real interest in her."

Makima stepped closer to Denji who was still sitting.

The boy gulped as she grabbed his hand and bit on his thumb.

"In order to feel a sense of fulfillment, you must know the person, Denji. That's maybe what was missing."

She'd let go of his thumb.

"Understood?"

"Uh huh!"

"Also... uhm, why am I going to school?"

It was a question that was kinda in his mind sometimes, but not always.

"So you can meet people your age and have friends that care for you." Her eyes was on his as she gave another smile that he really liked.

"Oh thanks."

"You should start going, you have another patrol to attend to after all."

She would put her hands behind her back.

"Yes, uh, Miss Makima." He stood up in a daze and walked out her office.

'Having friends is just more leveridge to make you break that contract after all.'
