This fanfic is rude and irreverent only with the intention of entertaining. The author took several liberties during its creation and you will see some rare fetishes throughout it. (Nijide)

If you don't like it, make your own version and send it to me because I want to read more fanfics of Bocchi x ChainsawMan.

Due to time constraints, the oneshot was ripped into several parts, enjoy the rock.

Obviously, I do not own Chainsawman or Bocchi the rock.

"Awawawawawawawaw."

There was she, that pink-haired girl and her chainsaw dog pet, fleeing from a horde of zombie yakuza.

As an introverted closet guitar enthusiast, ending up there was a story straight out of an anime or something similar.

Chainsaw Bocchi: The oneshot. - Part I

The world Hitori lived in was plagued by demons to the point where 7 out of 20 people died at an early age due to demons, but despite this, Hitori only had one goal in life: to be popular!

Since she was little, she was always the girl who was left out, the girl who ended up eating with the teacher on the school trip because no one wanted to be with her, the girl who most of her classmates didn't know and didn't even remember her name.

However, Hitori was proud of one thing, one thing that made her the happiest in the world and filled her with hope that one day she would be able to go out and make friends; when she was 7 years old and on a school trip near some mountains, she was forgotten by her classmates, the poor girl knew she was dead, that she had already died, she had cried a little and then accepted it; they had forgotten her to her fate and she would die of hunger sooner or later, so she decided to spare them the trouble of carrying her corpse (if anyone even noticed that she was forgotten and died abandoned in the middle of nowhere) and went straight to a nearby cemetery.

It was there that her life took a 360-degree turn, a somersault, a backflip, and also jumped from a plane, Hitori had the bad or good luck of meeting a boy and a dog that would change her life forever... (or not).

Hitori was under a tree, soaked, with her head between her legs crying when the sound of a chainsaw pulled her out of her stupor; there it was, in front of her: a dog with a chainsaw in its head. Hitori's mouth dropped to the ground as her body froze and stopped reacting. Then the pink-haired girl closed her eyes and accepted her fate, if she was going to die it was normal for a demon to come for her soul, she just hoped that a death by chainsaw wouldn't be too painful...

...

...

Who was she trying to decive?! That chainsaw was very scary! Hitori cried deeply until she realized that the poor dog was injured.

Suddenly, Hitori panicked not knowing what to do when she remembered that demons could heal themselves by taking human blood.

Hitori collapsed on the ground thinking that she would be the emergency medicine for that chainsaw demon. The demon only had to take a small bite and it was done.

The End...

Thank you for reading this little one-shot, I hope you enjoyed the story of how Pochita ate Boochi and became the true chainsaw man...

However, 7-year-old Hitori was not eaten. The poor demon collapsed on the ground beside her, almost out of strength. Hitori looked at the demon next to her, and her tender child's mind thought, "Huh? You're not going to eat me, puppy? You're also dying? I guess we're in this together..." Hitori started crying.

"I-I-I don't want to die here," she exclaimed while crying. A small "woof" came out of the chainsaw dog's mouth, and Hitori looked at it.

With tears in her eyes, Hitori hugged the little demon. "Y-y-you don't want to die either, right?" The words came out of the little girl's mouth with a mournful and sad tone. The little dog replied with a mournful woof as his eyes closed slowly. Noticing that the dog was starting to get cold due to the loss of blood, Hitori panicked and did the first thing that came to her mind: she put her entire arm in the dog's mouth. "AHHHH!" Hitori screamed and writhed in pain as blood flowed from her arm.

A few meters away, the Yakuza's car stopped for a second while the Yakuza peeked out wondering what that scream was, but he decided to ignore it. He had to meet with the son of the bastard who hung himself and left his son a terrible debt.

Meanwhile, Hitori writhed in pain with the chainsaw dog attached to her arm, but amidst this, she spoke out loud. "This is a contract, I mean, uh, sorry, but my mom told me never to give anything for free to a demon... She also told me that if I saw one, pretend to be dead... And I don't want to die either. I mean… Please save me! I want to see my mom and dad again! AH!"

The chainsaw dog lightened his bite a little while his wounds healed.

The unnamed dog looked with some pity at the collapsed girl with foam in her mouth and a small bite on her arm. There was some blood coming out of Hitori's forehead and she had bitten her lip until it bled.

The chainsaw demon started to worry, but the girl got up while still holding the chainsaw dog in her arms like a zombie, and started walking somewhere with a lost look while swaying from side to side.

Then the yakuza and the orange-haired boy turned to the zombie girl who had just appeared behind a tree with a chainsaw dog in her hands. Denji peed himself in front of the girl as pale as a dead person, and a chill ran through the yakuza in the car.

"F- find a way to get the money for tomorrow or..." Although the yakuza tried to ignore the girl and leave his ultimatum to Denji, Hitori's voice spoke.

"Eh? Debt? Yakuza? Am I dreaming? What's a chainsaw dog doing in my arms?" The girl's eyes seemed to be lost as if the impact from earlier had left her thinking she was in a fantasy.

The girl pulled on the chainsaw dog's tail and started walking towards them.

"Girl! This is none of your business!"

"Hehehe." Suddenly, Hitori started laughing softly. "Isn't this like the horror movie I shouldn't be watching? Does that mean I'm a serial killer?" Hitori approached the car and placed the chainsaw against the tire, causing it to explode.

Hitori took a wobbly step forward and cut the next tire in a few seconds. "Hehehe. Blood, yakuza, and chainsaws! Is today Friday the 13th?"

The yakuza got out of the car, looking alarmed, and pulled out a knife with an agitated expression. "She's a demon, she must be a demon!" The chainsaw dog barked and pulled Hitori's hands, swinging towards the yakuza and knocking the knife away.

"Eh? Who brings a knife to a chainsaw fight? Mu ha ha ha ha," Hitori swayed from side to side, swinging the chainsaw without aiming at anything in particular. The image disturbed the yakuza beyond words, and he ran away, leaving his driver behind, who also fled after getting out of the car.

"But wait, me, a serial killer? What will I do if the police come after me? I-I-I'll end up in jail, and they'll sentence me to death!" Hitori continued to babble nonsense while swinging the chainsaw before collapsing in the rain.

The rest of the day was complicated, but to summarize, Denji managed to save Hitori and gave her some of his blood, thinking that she was some kind of demon. He said they would make a contract to escape the yakuza somehow. Hitori didn't have the ability to contradict him and thought it was cool that he believed she was a demon or possessed. That night, they stole a car and ran away to who knows where until they ran out of gas and died hungry and desperate in the middle of nowhere.

Hitori woke up with a terrible headache that almost made her cry and a general body ache from not sleeping well. She rubbed her head, thinking about the horrible dream she had just had. Then she realized she wasn't at home and had a chainsaw dog sleeping next to her and a orange-haired boy resting in the other stolen car seat.

"What's the plan now, demon?" Denji asked.

"Woof," the pink ball with the chainsaw dog barked.

Denji raised an eyebrow at the sight of the dog and then covered his face. "The yakuza is going to tear me apart."

"Woof..."

"Demon girl, you're cool. I think I'll call you Pochita."

"Woof!"

"Eh? Are you happy with the name? I'm glad you like it! Although you couldn't talk before when you threatened the yakuza?"

"... woof..."

By pure luck, both managed to sneak onto a train in a luggage box that left them near Hitori's house, and like a dog that remembers where its home is (along with the help of Chainsaw Dog and Denji), the trio traveled 50 kilometers across Japan to reach Pochita's (Hitori's) house. But unfortunately, that is another story.

Hitori believed that this would be a change for the better or the beginning of a great story, but her parents turned out to be surprisingly understanding and seemed proud that their daughter had made a couple of friends. (Although they were a little worried that one of them was a demon.) However, they always wanted a dog, so they named the Chainsaw Dog Jimi Hen.

As for Denji's problem, Hitori's parents ended up in tears over his story, so they decided to adopt him, but to avoid problems with the Yakuza, they decided to dye his hair pink and cross-dress him, at least for the time being. With Hitori's pregnant mother, they couldn't afford to get into trouble with the Yakuza.

So "Nijide" (change the "j" to a "g," add an "i," and make an anagram) would have to put up with this for a while, and although he seemed to disagree with it, he didn't say anything because he was really desperate for some food.

So, nine years passed without anything happening... Until...

Six years later, Hitori was still waiting for her anime or manga story to begin.

Her "sister," "Pinkie," "Nijide," was having a great time. She always had a full breakfast with a toast full of a thousand things before going out in the mornings. In these five years, Denji had become a master of disguise, mastering both makeup and the art of padding, and it became quite evident that his tastes were not "out of the ordinary" when Hitori began to be careful about searching things in her "sister's" room.

If we ignore her sister's perverted gaze every time it was time to go to the locker room, Nijide's life was pretty good, and she had a lot of friends in high school, unlike Hitori, who locked herself in the house as soon as she arrived, spending a lot of time with Jimi Hen. It was at that moment that Hitori discovered rock music and started learning to play the guitar.

Another three years passed, and Hitori's high school ended. In the graduation photo, only her parents and sisters were there, while for Nijide's first year's end, there were at least 5 or 6 people. Oh, small detail, but Denji was actually a couple of years younger than Hitori, and like Futari (Hitori's other younger sister), was much more sociable than the older sister. However, maybe she should moderate her language a bit.

Over time, Hitori got used to Denji and started to get along with her, but Denji was such an airhead that she never realized that she was actually human and kept calling her Pochita and thanking her for saving her that time. And although Pochita was happy to have a nickname and someone to remind her of how she saved someone in the past, she felt like a piece of her was being ripped from her chest every time Nijide complained about rejecting a classmate who confessed to her or talked about her busty crush of the moment. Apparently, Denji had started to appreciate the fact that she could touch girls' breasts when she went to sleepovers while pretending to be a girl, but she complained about how they stopped inviting her and how they started calling her "the crazy of Yuri".

Hitori felt jealous of Denji's social life but even so she could only comfort him when he came crying when his "girlfriend" manipulated him and only wanted him like a piggy bank. Also since he only had a small amount of money from allowances Nijide always found himself without money and borrowed from Hitori.

However, it was when she met Nijika and Kesuku Band that her life truly took a turn for the better. Nijide was crying while watching her Pochita make friends, and Jimi Hen was jumping for joy as he saw Hitori make progress.

Then the school planned a field trip, and the nicknamed Bochita by Kesuku Band and Nijide, took Jimi Hen on the school trip in her backpack. She was too attached to Jimi Hen to separate from him even during their practices, concerts or school, in fact, she took him to school occasionally hoping someone would show interest and try to talk to her.

However, there was one little detail that she had not taken into account, she was once again forgotten by the rest of the people on the school trip, and even worse, it was in the same place where she had met Jimi Hen and Denji.

It wouldn't be long before the yakuza found Bochita, and the worst happened, Hitori Gotou was torn apart by zombies along with the chainsaw dog and thrown into a garbage dump in the middle of nowhere.

Chainsaw Bocchi: The Beginning.

Hitori woke up with a general body pain, thinking about the horrible nightmare she had just had. She could almost swear she had been torn apart by zombies, but luckily she had just fallen asleep in her closet with Jimi Hen on her chest...

Hitori looked at the chainsaw dog that lay on her chest and smiled as she lifted it into the air.

"Jimi Hen, you know I just had the worst dream, I was on a school trip when they left me behind and..." Hitori shuddered but shook her head as she smiled brightly at the chainsaw demon. "But never mind, the good thing is that I'm with you." Hitori hugged the chainsaw dog and noticed tears falling from the dog's eyes.

Hitori stroked the chainsaw dog's head. "You know, Jimi Hen, I think I've told you before, but I'm too clumsy and I'll probably get eaten by a demon someday. I think I mentioned that if I got eaten with you on top of me, I wanted you to take control of my body so you could get revenge for me. But you know, I'm living such an amazing life. Although I wish I could communicate properly with other people... Maybe get someone outside the family to hug me..."

Hitori shook her head and smiled at the chainsaw demon. "But everything will be okay as long as I'm with you."

The chainsaw dog's eyes were crying tears like a waterfall, then its precious dog mouth moved as it spoke. "I had a lot of fun watching you day by day, Pochita."

Hitori was petrified as she heard the dog speak, only then realizing that she was still inside that garbage container, and her brain crashed. However, something in the way her pet called her by her nickname filled her heart.

"Bochita, I'll become your heart, but this isn't free, this is a contract; show me many more of your dreams."

"Jimi Hen!" Hitori stood up from the trash can with a scream.

"Huh? You're still alive after I tore you apart? Disgusting. I hate devil hunters, but this is why I completely despise musicians, you just won't die after being torn apart. Killing you was the best thing I could have done. Seriously, your last album was terrible! My zombies! Feed her to the pigs!"

Hitori placed her hand on her chest and found Jimi Hen's tail coming out of her chest. Tears welled up in her eyes as she began to panic. "Idiot! I'm too useless to take revenge on my own, that's why I wanted you to do it for me! Come on! Get out of there and help me!"

Hitori pulled on the rope in a panic with tears in her eyes, but by the time she realized it, she was surrounded by zombies.

Hitori was devoured.

The en-

Brrrrrrr!

"Get the hell off, you shitty bastards! My fucking pet just became my heart, and I'm having a mental breakdown right now!"

Chainsaw Bocchi rose from the bodies of the zombies, her head completely transformed into a chainsaw with a pink handel, and a pair of chainsaws on each arm, with a disgusting tongue coming out of her mouth.

"Damn it! This hurts like hell, but it's so damn rock 'n' roll!"

Chainsaw Bocchi writhed in pain but didn't become lazy as she killed zombies left and right.

"Damn it! It hurts like a fucking lot! Fucking zombies! Can't you see I'm having a bad time right now? Wait! Does talking to zombies count as taking a step forward in my dream?" Chainsaw Bocchi pierced another zombie's head while thinking.

"There's no fucking way that will happen! But the demon should count! HEY! MR. ZOMBIE DEMON, I'M SELLING TICKETS TO MY NEXT CONCERT!"

"What? I've been looking for tickets to your concerts for a while, but after your last album, no! I hate musicians!"

"THEN DIE!"

(Note: Bocchi's personality changes when she becomes a chainsaw because it's so damn rock , and because let's be honest, between the pain of transforming and the illusion of power, Bocchi would commit genocide. (In another note, Bocchi can't kill a fly, but Chainsaw Bocchi can at least stand up to demons.) (In another note, if you don't take care of your Bocchi in a world like Chainsaw Man, she'll die.))

Makima and the muscle demon.

The sun had risen and a car parked next to an abandoned factory, three people in suits got out of the black car, two men with hats and a red-haired woman with yellow eyes and a braided ponytail.

They all walked into a room where they found a messy hell of chopped zombies and in the darkness stood a humanoid figure with a large chest, a torn sports hoodie that only covered enough to be able to show the show on children's television (because showing disembowelment is quite childish) and several chainsaws on its body, one big one on its head and a couple more on each arm.

"Miss Makima, there is still one alive," commented one of the men.

Makima stepped forward and looked him in the eyes. "Did you do this?" she asked with a slight nod of her head.

Then a slight and timid almost robotic voice escaped the creature's tooth-filled mouth. "Hug-me... P-p-p-please, i-i-i-if it's not too much trouble," before collapsing under its own weight, but Makima did not let her fall, instead she hugged the girl who was slightly shorter than her.

Little by little the chainsaws melted away revealing the tired and pale face of a high school girl with unfocused eyes and a lot of dirt and dry blood on her. "You're still human," she commented with a warm smile as she stroked her hair. Hitori shuddered at the touch as her eyes focused on the person who was hugging her and her body tensed for a moment. "You have two options, little one," Makima began as she stroked Hitori's hair. "You can be killed like a demon, or you can live as my dog. What do you choose?"

Hitori, not knowing what to do, resorted to the same thing she did when she first met Denji: "woof!" Pretend she didn't know how to speak and bark. Makima's smile grew slightly larger as she took off her jacket to cover Hitori's bare chest while her gaze lingered for a second on the rope hanging over Hitori's chest.

Once in the car, Makima tried to talk to Hitori but only received a shy look and woofs in response. She introduced herself as Makima and said she was a demon hunter, asked for her name but all she got was "Bochita", although most of the things Hitori said were "woof", Makima told her that she would now be working for her hunting demons and that she only wanted a yes or a woof in response. Makima was slightly worried that the girl seemed too cautious in her presence so she decided to take her out to eat something before going to headquarters. But on the way, she was notified that a demon had kidnapped a girl nearby and decided to send the red-haired girl to deal with it, Hitori's response was: "woof..."

Facing the muscle demon, Hitori did: "Awawawawawawawawa" without knowing what to say to the girl who seemed to be a friend of a demon like she was a friend of Jimi Hen. So she decided to run away, it's not like she was too socially awkward to make contact, it was mercy! Mercy from the great Hitori!

Hitori imagined herself in the future being a music celebrity and telling the story of the time she released a demon that was friendly with a girl because of her great mercy, while the audience cheered "Chainsaw Bocchi! Chainsaw Bocchi!" and she pulled on the rope on her chest and started playing with her band in the most rock and roll way possible.

However, Hitori was pulled out of her dream world when the muscle demon hit her from behind. "And to think you would realize my deception, as expected of a guitarist, it's a shame I can't get an autograph of the most famous guitarist in hell before killing you. Now die!"

Crying in pain from the blow, Hitori put her hand on her chest and pulled the cord.

Brrrrrrrrr

"CHAINSAW BOCCHI TAKES THE STAGE! LOOK HOW MERCIFUL I AM, YOU BASTARDS!"...

Author's note

I already mentioned it before but I'm going without reins with this fanfic so don't expect too much seriousness from this parody, this oneshot will cover until the pistol attack and the death of Himeno so it's not very long, maybe I'll do a second part when this one is finished.

The general premise is "what would I do bocchi in Denji's place" and since I didn't want to leave denji without a pocchi or just pretend it didn't exist I decided to give him a happy ending. (however my fetishes forced me to transvestite him after seeing a similar image on twitter)

See you for the next part in not too long.

Sincerely.

"I already wrote the end without having finished the middle part"
