The King Of Curses(Chainsaw Man)

In Tokyo Japan, on September 3rd, 1988 walking through the city a boy who was 11 years old and indirectly drawing attention to himself. He was wearing a solid dark blue button-up sweater, with a tight black undershirt beneath. 

At the same time, he was wearing some black and red basketball shorts with a pair of solid black Jordans. His hair was jet black and rather spiky. As he walked, he held a large McDonald's cup with Sprite in his right hand. 

In his other hand, he held a large burger which he was biting into, no cheese. All over his body and face, he had black Cursed Tattoos which caused people to stare. Japan wasn't accepting of tattoos much less of a child his age. 

He was fairly eye-catching, but his companion was probably more eye-catching than him. She was tall, beautiful, and quite muscular compared to most women. She was around 6'4 with a pair of black wolf ears pointing out of her head. She also had a black fluffy tail wagging behind her. 

People stayed away as it was obvious she was either a Devil or a Fiend. The more human a Devil looked, usually the friendlier they were. This was the case with her as she was the Wolf Devil, manifested from the fear of Wolves. 

All things considered, she was rather 'friendly', but still made it clear she hated humans. She didn't even consider him human and he let her stick around as his bodyguard and she was good to look at. 

Plus, he liked dogs so having a wolf girl was not bad if he had to be honest. When she did revert she looked like a large werewolf. He named her Delta, but he sometimes called her Moron as she was dumb as bricks. In her arms, she held several burgers which she was gorging on.

Every time she opened her mouth her set of wolf-like teeth were revealed.

"Slow down, you're going to choke."

She shook her head.

"I won't."

"Sure you won't." 

He took a giant bite from his burger, but suddenly Delta began to sniff the air. Her ears started twitching before she turned to him with excited eyes.

"A DEVIL! MASTER, LET'S GO EAT IT!"

He shook his head at her. 

"I need the body to sell, Moron."

Her ears dropped and so did her tail as she began kicking her feet.

"BORING!"

He reminded her why they needed the body intact. 

"We need money for food and the internet idiot."

When he said food and internet she remembered. 

"Oh, we need that."

"Duh, come on then."

As they started walking toward the Devil, people started running in their direction. At first, it was just a few, but then it became a large flood of fleeing people. 

"A DEVIL ON THE LOOSE!"

That caused even more panic as it seemed a whole swarm of panicked humans were fleeing for their lives now. As people rushed toward Sukuna and Delta she made sure to aggressively shove or straight up throw people out of his way.

The more negative emotions around him the better as that was how Cursed Energy was generated. His Cursed Energy reserves were borderline limitless just like the King of Curses. He crushed his burger wrapper and tossed it on the floor along with his drink. Littering didn't matter when it was a chance to make money. As he and Delta walked toward the source of the chaos, he started grinning.

Cursed Energy started flowing through his body before they rushed forward. Both of them lept above the crowd of fleeing people to not have to cut through them. He and Delta ran at full speed as if any other Devil Hunter got there before them they would lose out. 

When they made it to the Devil causing a ruckus, Sukuna took in the sight. The Devil was not particularly large and had the shape of a giant crow creature with three heads and large black wings. All over its body, it had what appeared to be human arms, legs, and eyes growing on random. 

Even on the sides of its head, it had hands to shove food in its beaks. It was about five meters tall and it was rampaging through the city center. At the moment it seemed to be tearing into a few people it managed to snag before they had a chance to flee.

He turned to Delta who was starting to jump in place. 

"I got this one." 

"Right." 

He approached the Devil until he was only a few feet away from it. 

"Yo." 

The Crow Devil raised its three heads looking at him. When it did so, it started salivating as it began sensing the immeasurable amount of Cursed Energy flowing through his body. If it managed to eat him it would evolve as a Devil. 

However, another part of it felt fear as it almost felt like he was a Devil himself.

"WHAT ARE YOU? A DEVIL! THIS IS MY TURF!"

"Me? Just a Jujutsu Sorcerer."

He swung his right hand diagonally as he used Cleave to slice the Devil's three heads off. When its three large heads fell, the body followed suit. With the Devil dead he remembered how he ended up as a Ryomen Sukuna. 

Eleven years ago, he had been 22 years old and finishing up his 4 years of enlistment to the US Army for college benefits. During his time, he was stationed in Japan and through his Weeb Friends got into anime, especially in the birthplace of Anime, Japan. 

He had become a huge fan of Bleach, Dragon Ball, Hunter Hunter, Misfit Demon King, Chainsaw Man, and Jujutsu Kaisen. When he died, it wasn't anything out of the ordinary. He had been crossing the street and a drunk truck driver ran him over like he was an Isekai Delivery driver.

When he died, he probably met a ROB, but he could not remember. That encounter was erased from his mind, but he did the skills, talents, and memories of Sukuna. He even got the Ten Shadows which was a Godsend in this dangerous world. 

Both Techniques helped as he had been born an orphan in Tokyo. His first four years had been a little rough without his technique, as they only manifest around age 5 to 6 when a child has an Innate Technique. 

He did have Cursed Energy to rely on which helped keep himself alive. Then, when his Technique awakened at age four, he left the Orphanage to become a Private Devil Hunter to support himself.

Two years into his career, he ran into Delta who was being chased down by some Private Devil Hunters. He saved her life and in exchange, she became his bodyguard. 

"Delta, come here." 

She jumped over to his side, with a wagging tail. He grabbed one of the crow heads before he raised it and he opened his mouth. His teeth began changing into what seemed to be fangs. 

He then bit into the flesh tearing a large chunk out. He then passed it to Delta who did the same. In Jujutsu Sorcerers, Cursed Energy flowed through the whole body while in Devils Negative Energy was the Cursed Energy equivalent. 

Both Energies were nearly identical and he could increase his reserves by consuming Devil Flesh. He usually took a few bites from the corpses of Devils, as he didn't have a Uraume who was good at cooking humans or Devils. However, he was right as he could increase his Cursed Energy reserves this way even if it was disgusting. 

If he ever wanted to have a chance against some of the heavy hitters like the Four Horseman like Makima, he had to be strong. Mahoraga and the Ten Shadows would bridge that gap as well to keep themselves alive. 

As he and Delta passed around the head, he noticed some Public Safety Devil Hunters in their black suits. When they saw him chewing, they hid their grimaces as he was quite famous in Tokyo as the youngest private Devil Hunter. There was also his habit of snacking on Devils and his 'bodyguard' the Wolf Devil, a particularly friendly, but violent Devil. 

"You're late."

He spat out some bloody saliva which the leading Devil Hunter recoiled at. 

"Do you always have to take a bite out of them, Sukuna?"

"Part of my Devil contract."

He stood up from the corpse before he walked toward her.

"How much for the Crow Devil?"

The Devil Hunter walked forward and looked at the state of the course. The heads had been cut off cleanly, but its main head was being eaten right now. 

"It is a good one and would have been 450,00 Yen(2,926.35). But since you two went and ate one of the heads, 25,000 Yen(163$) will be deducted."

He didn't mind as he was gaining some Cursed Energy from that Devil. He tossed the head in the air and caught it. 

"I will take it, got a checkbook?" 

She sighed and reached into her coat pocket before she began to write a check for 425,000 Yen(2,763 dollars). She then handed him the check which he put into his pocket. 

"Thanks." 

He then tossed the Crow Head toward Delta who punched it to crack the skull. She started tearing into the Devil's brain before ripping out half. 

"Master, do you want any? The brain is soft." 

He held his hand out and she handed him half. He tossed it in his mouth and he swallowed. He spat out some bloody spit as he didn't eat these because they were tasty. 

"I am done, you can have the rest." 

"YAY!"

He started walking away, with Delta, but the female Devil Hunter called out to him.

"Wait."

He turned around uninterested.

"What?"

"Won't you join the Public Safety Devil Hunters?"

"Become a Civil Servant? Fuck no."

Delta stuck her tongue out at her and dropped the flesh bare skull. He just walked away with his hands in his pockets. When he and Delta were gone, one of the three Devil Hunters turned to the women who spoke to him.

"I get he had a contract with that girl, the Wolf Devil, but what is the other Devil he has a contract with?

She shrugged.

"We don't know. Since he showed up 7 years ago, we know two things. He can release slashing and cutting attacks. We don't know much else about him. The higher-ups think he has a contract with a possible Cutting Devil or Slashing Devil, but that is yet to be proven.

As for the Wolf Devil, five years ago, she viciously mauled an Animal Control Worker. She didn't like how he treated her pack, which was just a bunch of stray dogs. He ended up dying and some rookie Private Devil Hunters went after her. 

Only to run into that kid who ended up saving her. As for his name, if you ask him he will tell you his name is Ryomen Sukuna, like the spirit. Though, in public records, he is labeled as Akimitsu Haruo." 

One of the Devil Hunters shook his head. 

"He is weird, eating Devils and raw even. What even is his deal?" 

She didn't answer as she pulled out her phone to call in about the dead Crow Devil. 

"I am not sure, though Miss Makima is interested in him. She is quite determined to bring him into The National Devil Extermination Public Safety Commission. She sent him a letter a year ago and his response was, only one word. No." 

---

As for Sukuna and Delta, they eventually walked to the Tokyo Suburbs where he lived. As a Private Devil hunter, he had hunted a lot of Devils, some a bit stronger than normal so he had quite a bit of money saved up. 

He managed to find a house for sale for only 25,00,000 Yen(163,000 Dollars) because the previous owners had been killed and eaten by a Devil. The grandfather of the previous owner was in depression and just wanted to sell it quickly. 

This means he bought it at half the price of what it would have been worth. When he unlocked the door with his key, he was met with a bunch of dogs running at the door. 

"SIT!" 

With his order, all 5 dogs sat down. Delta rushed in and hugged all five as these were her 'pack' as she called them. 

"WE'RE BACK!" 

He smirked as he kneeled and he started petting his dogs. Two German shepherds, two Pitbulls, and a Japanese Akita. Delta wrapped her arms around him and hugged him. She liked that he let her whole pack move in with him when he saved her. 

"Dogs are great aren't they." 

He wasn't complaining as his head was being smothered right now.

"Sure are." 

He patted her hip for her to let go, so she relieved him. With the Crow Devil killed, he just had to cash in his check and he was good. He would need to keep hunting Devils, as it was good money and good training. 

He also had tamed all of the Ten Shadows except Mahoraga. If a 15-finger Sukuna could get it done, he could do it as well. He just wanted to find a safe hidden place as releasing a Domain Expansion like Sukuna did and Divine Arrow would be dangerous. 

"Have fun Delta, I am going to my room." 

"Got it, Boss."

When he entered his room, he had an American-style King Sized Bed as he didn't like sleeping on Japanese Futons. When he got onto his bed, he crossed his arms and placed them on his stomach. 

He started circulating his Cursed Energy through his body to make sure the Negative Energy he got from eating the Devil didn't cause trouble. At times like this, he called back to the hundreds, if not thousands of times Sukuna did this after eating people and Sorcerors. 

So he had an example to call back to and he wasn't without instruction. In his eleven years by using the memories and experiences of Sukuna, he knew RCT, Dismantle and Cleave, Divine Arrow, and in theory Domain Expansion. 

He hadn't used it yet since he had not needed to do so, but knowing Makima, he would soon. 

(I decided to roll it and add the Ten Shadows. Mahoraga vs Gun Devil Gif was cool and Megumi Sukuna looks cool.)
