Bony Boy goes to JJK World

Hello there, Author here. Man, this chapter was a bit harder than usual to write thanks to the absurd number of characters that showed up. I have placed at the end of the chapter a small breakdown of the teams. I will fill in the rest of them once they show up in the chapters. If it starts getting a bit too confusing I can do a more detailed breakdown if you guys want.

Thanks for reading the story thus far, have a great day.

-Lots of spoilers on JJK read at your own risk.-

It was a dark dank location. Ainz and Geto walked inside the hideout while keeping a good distance from each other. Neither of them was particularly excited to meet again so soon, but they both had no choice.

Ainz walked ahead following the traces of cursed energy through several corridors before reaching a locked door. He placed his hand on the metal and said, "Is this it? "

"Yep. This is the rat's nest. " Geto said while nodding. It had taken quite a while before the jujutsu sorcerer gave away his real location and even more time to get Ainz to do it, but he had done it.

'One less problem to deal with. ' Geto thought as Ainz pushed to the door. The rusty squeak that the door made alerted whoever was inside who immediately called out to Ainz and Geto while saying.

"You took too long. I'm getting tired of waiting. " The man laying down inside a bathtub said. They opened the door and walked in.

The room was even darker than the corridor with only a few candles around a bathtub in the center of the room. The smell of putrid smell of blood or whatever it was inside of it made Geto look away from the smell as he realized the state of his informant.

Both Ainz and Geto stared at the jujutsu sorcerer who was missing his right arm. He was covered in bandages and had a lot of medical equipment constantly monitoring his vitals.

"I'm sorry, Mechamaru. We were rather busy getting things ready for the Halloween party Ainz planned. " Geto said with his normal voice.

"I heard about it from the others. Are you really going to go through with that? You should have kept your original plan and sealed Gojo. " Mechamaru said while scratching his face. "I read the rules and they don't keep Gojo from participating so you're gonna lose-. "

Ainz's eyes flashed red when he heard the taunt. He started walking toward Mechamaru shutting up the boy. "You talk a lot for a rat did you know that? " Ainz said as he shook his head.

Mechamaru was always in pain thanks to his heavenly restriction which gave him great amounts of cursed energy in exchange for his body's health, but after seeing Ainz approach him with a strange aura surrounding him. Mechamaru forgot about the pain for the first time in his life. 'I heard this curse beat Gojo, but I didn't expect it to be this intimidating. ' Mechamaru thought as Ainz got closer and closer.

"You have been very disrespectful to me. Normally I would punish you, but it seems if I do that Geto here will pay the price. " Ainz said before pointing at Geto who immediately shrugged.

Geto placed his hand on his chin before saying, "It's true that I did the binding vow with Mahito and you have nothing to do with it Ainz, but if I were to become unable to participate in your gathering... that would be a problem for you, right? " He finished by lifting his finger to emphasize his next point. "I wonder what would happen to your party if I hid the 10 fingers I-"

Ainz raised his hand interrupting Geto. They had both agreed that Ainz would take care of his little problem or Geto would only participate with one team.

'Sukuna's vessel has 3 fingers in him, limiting the total number of contestants to 51 players. If Geto does not go all out, the total would drop to just 24. I can't let that happen ' Ainz thought as he remembered the conversation he had with Tengen.

Ainz looked into Geto's eyes before turning back to Mechamaru. The displeasure he felt toward this makeshift deal he was forced to make revolted Ainz. Yuki had told him that the jujutsu sorcerers had most of the fingers sealed inside the school already and the fact he ended up giving the edge to Geto made him sick. "Don't forget to give Mechamaru 4 fingers for me. "

Geto placed his hand inside his sleeve before pulling out the sealed fingers. They were all inside a glass jar with a red ribbon around it. "I sealed them up for you. As soon as you heal them it will be given to him. "

"And? " Aniz asked right after stopping in front of Mechamaru.

Geto took a deep breath and responded, "I won't try to get them back or attack the kid or do anything else to the jujutsu sorcerers. I will just get ready for the game. Happy now? " He said in a bored and dismissive way.

Ainz nodded. "It will suffice. " The undead's eye flashed as he pointed his hand to Mechamaru who had remained quiet ever since Ainz started walking toward him.

Mechamaru swallowed in fear and after stuttering a few times he asked, "Can you really turn my body into a normal one? "

"The deal was to turn your body into a normal one. In other words, you hope to be able to walk and to feel any pain anymore... I can do that. " Ainz then touched Mechamaru's shoulder making him wince in pain.

[Greater Break Curse]

Mechamaru felt his cursed energy levels drop sharply while the pain tripled. "What did...y-" He tried to say while doing his best to contain himself.

[Greater Healing]

A wave of Reversed Cursed Energy entered Mechamaru's body allowing it to grow a new arm and restore the function of his legs. Soon after that, Mechamaru stopped feeling pain. 'I'm... cured. ' Mechamaru thought as he pulled out the tubes he was stuck with for so long before jumping out of his bathtub.

Ainz tilted his head as he saw Mechamaru check his new self. "Anything unusual? " Ainz asked as he had to make sure the body was a perfectly healthy one in order to fulfill Geto's vow.

Mechamaru quickly removed the bandages and examined his new arm. He opened and closed his hand while closely watching the muscles contracting. 'It's perfect. ' Mechamaru thought before looking at Ainz who was just as interested as he was in whether or not the body was complete.

Mechamaru took a deep breath, his hands started trembling and his heart rate skyrocketed before he said the next few words. "Now that the deal is complete... There's nothing to stop me from attacking any of you, is there? " Mechamaru raised both of his arms while sending out commands to the cursed dolls he had prepared to kill Mahito and Geto.

Ainz's eyes flashed for a moment making Mechamaru take a step backward. He bumped into the bathtub before he was able to throw a single attack.

Geto covered his mouth while trying to hold back his laughter. "Look at this guy... " Ainz didn't find the show very amusing as he simply turned his back and started walking.

"Geto made a vow to me not to go after you or any other jujutsu sorcerers until the game starts. On the other hand, I can do as I please. " Ainz said while displaying a portion of his power. The cursed energy he released pushed Geto's clothing around a bit forcing Geto to hold them down with both his arms.

While a minor inconvenience was all that happened to Geto, Mechamaru was thrown back a few meters. He fell into the bathtub dislocating his shoulder. 'Impossible. I'm sure I used cursed energy to block the attack... Where is my cursed energy?! ' Mechamaru thought as he finally noticed a significant drop in his cursed energy levels. He was now sporting around 20% of his regular power.

"What happened to me?! " Mechamaru said as he got up from the bathtub. He immediately looked at Ainz who stopped for a moment.

Ainz slowly turned around before explaining, "Your heavenly restriction gave you most of your cursed energy, but also prevented me from healing your body. Once I got rid of that I healed you. That is all. " He explained to the jujutsu sorcerer who quickly realized the problem with his wording of the binding vow.

"Turn my body normal. " Mechamare reiterated the deal to himself with a slow and calm voice. He immediately understood the meaning behind the question Ainz had asked him before fixing him. "This isn't it. Mahito promised -"

Geto raised his voice saying, "When I told you about Mahito's death and offered the alternative to your problem you accepted right away. Ainz here got you a regular body and that's that. "

Ainz nodded before continuing his explanation. "I didn't touch your cursed energy and I certainly didn't do anything that would be considered unfair or unjust. I abided by the contract and turned your body into a healthy one. The fact you dropped to a third-grade jujutsu sorcerer is just a consequence of that. "

"I didn't know that I would lose my-" Mechamaru was about to go on a rant before Ainz teleported right in front of him. The overlord grabbed Mechamaru before giving the final explanation.

"I could just simply kill you now or just turn you back into what you were a few minutes ago, but I need you to deliver those fingers to the people at Jujutsu High... If you wanted to keep your cursed energy you should have asked me to transfer your soul to another body." Ainz explained with a terrifying tone while staring deep into Mechamaru's eyes. He then let the boy go with a final display of cursed energy pressuring Mechamaru to bow to the might of Ainz Ooal Gown.

Ainz turned to Geto who was looking at him with a very satisfied expression. "The fingers. " Ainz said as he lifted his open palm to Geto. The curse user threw the bottle and immediately turned around and walked away from the door.

Ainz grabbed it in mid-air and then placed it on the ground. "The people at your school have zero fingers right now so unless they find one of the seven that remain out there they won't participate at all, that's not acceptable." Ainz's eyes flashed as he walked toward the door. Geto left " I want to make sure Gojo will be there so bring the fingers to them. "


It had been only a few days since Ainz had announced the games, but Jujutsu High was already up in arms about it. Gojo and Yuta had decided to be team captains while leaving both Yaga and Gakuganji to decide what the hell they would do with the other 7 invitations they had.

While in theory, they could have a total of 27 players in there at the time, they had just lost all of the Sukuna fingers they had collected over the years leaving them no other option but to scramble to find more.

'If Ainz gave us 9 invitations that means the other curses must have the other 11. ' This was the theory presented by Gojo before he left in the search of however many fingers he could find. Yuta, on the other hand, was called to protect the school in case the other contestants decide to cut off the competition earlier.

Yaga was in his office trying to figure out who to send out after Yuji who was captured by Ainz before the announcement. 'We lost the initiative... Our chances of winning this are very slim and the curses hold a massive advantage over us. ' He thought as he looked out the window.

Try as he may, Yaga couldn't take push away the feeling that Ainz would feed Yuji the fingers to diminish the number of competitors, even though it would run counterintuitive to the purpose of the game. 'He wants to exterminate all of the possible threats and to do that he's giving himself in a silver plate for anyone who can get to him. There's no way that he would bring Sukuna back before that game, but that does not mean he's not gonna get close to it. '

"Goddamit. " Yaga said as his cell phone started ringing. He quickly pulled it out of his pocket and answered.

"This better be good news, Mei Mei. " He said with an impatient voice. It had been a few days of nothing but silence from the Kyoto branch, according to Utahime, even Gakuganji had removed the order to kill Yuji.

'Did Ainz finally make a move?! ' This was Yaga's first thought. He couldn't think of another reason for the Kyoto branch to communicate right now since the only thing they could be possibly doing now is to go after more Sukuna fingers and Yaga knew that they would not share them with the Tokyo branch.

"We have 4 fingers with us. I'm gonna bring 2 to the Tokyo branch in the next few days. Prepare a good seal for them. " Mei Mei said with her usual flat and uninterested voice surprising Yaga.

"How did you get 4 fingers? More importantly, you're gonna share? " Yaga said as he tried to understand what the first-grade sorcerer just said. The fact that they would reveal such a piece of information was already surprising, but sharing them was crazy.

"That curse scared the higher-ups that much? " Yaga asked as he raised an eyebrow. He knew that is the only reason that they would be willing to help them like that.

"Before this, they didn't give a shit about helping out Gojo even though he was the only reason that the curses are losing, but now that their necks are on the line it's all hands on deck. People in power are always gonna be like that, Yaga. " Mei Mei said before moving on with the conversation.

"Anyway, there's a condition to this deal. I don't think I have to tell you, but you need to send Gojo and Yuta in separate teams. " Mei Mei said.

"Obviously. " Yaga replied. "Now that there are only 3 fingers out there we need to be very careful about choosing the people we gonna send in."

"We didn't find the fingers. Mechamaru gave them to us. " Mei Mei said before she pushed the phone away from her ears.

"What?! Are you saying he was hiding 4 fingers from us?! " Yaga screamed after he began pacing around the room. He made it halfway across the room before he bumped into the table which prompted him to kick the poor thing.

Mei Mei placed the phone closer to her ear to make sure that Yaga was done before saying, "He didn't find them either. Ainz gave them to him. "

This made Yaga stop. "Ainz? Impossible. " His mind began to work 100 km/h as he tried to come up with a good reason for doing that.

'Why go through the trouble of stealing the fingers and then giving them back to us? It makes no sense. ' Yaga thought.

The confusion gave Yaga some time to calm down. He exhaled after giving up, he couldn't find a rational reason for Ainz's actions. "Why did he do it? " Yaga asked.

"He said he wanted Gojo there. " Mei Mei said.

Yaga scratched his head. 'No rational reason. ' Yaga thought t himself as he started chuckling. 'No rational reason indeed. '

"Thanks for the info, Mei Mei. I'll tell Gojo and Yuta about it and get a team ready for the fight. " Yaga said.

"Bye. " Mei Mei said before ending the call.

"At least now we're in the game, one problem fixed..." Yaga said to himself. Although Jujutsu High was guaranteed to show up he still had no idea what the other contestants would be and Yuji was still missing.

'Ideally, we could get some more info on Yuki, but she vanished. ' Yaga thought as he went through his sources. They had no way to know what group Ainz had been working with, but they were sure to show up sooner or later.


Yuki was sitting down in a queen size bed while listing to some K-pop music. She was in an expansive hotel room in the Bahamas with a great view of the hotel pool. The most attractive people she had ever seen walked the lounges and enjoyed themselves in the resort while she was stuck in her room with two teenagers.

She got up and picked up one of the snacks Junpei had bought a few hours ago before going through the fridge and grabbing a beer.

Junpei was sitting on a chair near the corner of the room. He was wearing a casual tourist outfit, a green flower shirt, shorts, and sandals. "Are you sure you should be drinking that? " Junpei asked her.

"It's no problem. As long as I keep watching the room. " Yuki said as she opened the can. "What about you? You're just gonna stay here? Ainz didn't tell you to stay here watching Sukuna's vessel."

Yuki said as she pointed to Yuji who was still unconscious on the bed. Junpei quickly looked at Yuki before saying, "His name is Yuji... and no. I'm gonna stay here until this is over."

A red void manifested inside the room prompting both Yuki and Junpei to stand up. She quickly hid the beer back into the refrigerator before looking back to the portal.

Ainz slowly made his way through. After dealing with Geto, he had to make sure that his player and Yuki understood exactly what they had to do during the game.

"The jujutsu sorcerers have 4 fingers now. With Geto having 6, and Yuji having 3 there are now only 6 fingers available. " Ainz said as he placed his hand inside his inventory.

Yuki shook her head. "First that's not Geto. Geto is dead. " She said after lifting one finger. "Second, it's 7 fingers left. There are 7 fin-"

She stopped talking when Ainz pulled out a finger from his inventory. The overlord then looked at her before giving the finger to Junpei. "This is your fee Junpei. You'll enter the Domain as a player and try your best to stop everyone from getting to me."

Junpei nodded. "What about my equipment? Are you gonna give me more armor or..." Junpei asked while trying not to look down. In his mind, the loss of the armor was a great blow to his worth as a pawn, little did he know that the armor was just blue gear trash Ainz forgot to throw in the recycling bin.

"I'll give you similar equipment and some supplies so you can survive in the Domain, once you're in there you are to find the guardian of the first layer. She will have your new gear." Ainz explained as he placed his hand inside his inventory. He pulled out the same armor he had given Junpei and then placed it on the floor. "Avoid confrontation if possible, the first layer is bound to be a killing zone."

"What about me? " Yuki asked.

"I want you to go into the Domain with Yuji. Make your way into a deeper layer and hide until the game is over. After that, I'll feed Yuji the fingers we collect and perform Dark Wisdom. " Ainz said as he created a chair for himself.

"Once that is done. You get what you want..." Ainz pointed at Yuki. "A world where no new curses can be born. "

Yuki smiled and nodded.

"Listen you two. The curses in my Domain won't attack you but don't put your guard down. Once Gojo and Yuta make their way in, I'm not sure how long the defenses will last. " Ainz said as he stared into the distance. "Even without resistance from the locals, you might be picked off in the first layer by another jujutsu sorcerer. Don't fail me. " Ainz's eyes flashed making both Yuki and Junpei nod.

"I'll make it all the way to the 6th layer in no time. It's a forest, right? I'm just gonna hang out there. " Yuki said as she pictured herself resting in the shade.

"Understood. " Junpei said with a serious voice. Unlike Yuki, Junpei had issues with this mission, and the fact that Yuji was gonna be sacrificed was eating at him. He thought about raising his opinion, but the fact that he was just a paw made him hesitant.

'It's going to be just like my mom, isn't it? ' Junpei thought as his mind started to wander.


7 weeks passed as everyone scrambled to find the remaining fingers. During this time, Gojo was able to find 3 more totaling 7 fingers to the jujutsu sorcerers.

Geto was able to get 2 more increasing his participation to a total of 24 active players which left only two fingers that were unaccounted for. While Geto knew that he couldn't interfere directly with the jujutsu school, he could still use his spies to get some info, but even then he was unable to locate the remaining two fingers.

"Other players must have found them. I wonder who they are. " He said to the group he had assembled. There were only a few minutes before the main event of the year started, but he couldn't wait to check out the people who would be playing the game.

To his left, he had 3 groups totaling 12 players. All of whom were curses. "Eso, Kechizu, and Choso I want you guys to go in first. The others will follow a few minutes later. " Geto said while looking at the team he dubbed the cursed womb team.

"Jogo you will go in with Dagon and the Grasshopper curse. You'll be the second team to go inside. " Jogo released a puff of smoke from the top of his head.

"Do the best you can to clear a path for me, rookies. " Jogo said while smiling at the cursed womb team. Choso rolled his eyes as he simply wanted to get the meeting over with.

Geto turned to the ball-shaped curse flying around the room. "Lance. You'll be the one responsible for the third team, but I don't want you to actually win the game. Go after the jujutsu sorcerers. " The third team was dubbed the New Age. They had Nairu; the special grade curse born from the fear of nuclear weapons; the cockroach curse and the first-grade curse Veth, who was born out of the fear of violence.

The ball spun around in the air before they all left the room leaving only the curse users. A total of 5 teams were made up of jujutsu sorcerers of the past and the few people Geto had worked for him before.

"Why are you sending curses as their own teams when you can go yourself and bring them out in there? " One of the curse users asked. She was a naked lady who used her sky-bending cursed technique to cover herself.

Geto looked at her and smiled. "We don't know if the Domain will count each of my curses as an individual player, besides they don't have much on the jujutsu side anyways. Let's just send in the fodder first. "

Uro, one of the jujutsu sorcerers from the past, looked at the other two around her before asking. "Are you really putting me with him? "

"Don't be like that. Once you're in my Domain you are free to do as you wish. " Geto explained to her.

The team she was in was made of Ishigori, another jujutsu sorcerer from the past, and Dhruv Lakdawala, the second incarnation of a very powerful curse user. The second human team was made up of Haruto Shigemo, Uraume, and Iori Hazenoki

Unlike the curse teams, none of them had any orders about what they should achieve once they got inside the Domain. They were free to pursue whatever goal they had in mind.

This was the only way Geto found to make them work together or at least agree to pretend that they would work together.

Geto used many cursed objects to turn regular humans into curses or to reincarnate jujutsu sorcerers from the past.

All of them surely had many different goals and some might even oppose Geto's, but since he held the invitations and he held the fingers they had no choice but to make a vow that they would not clear the game.

"That's exactly what I'm planning to do. " Hajime Kashimo said. He was leading a team with himself and two of Geto's former associates into the game. "Let's just go already."

Geto raised his hand before explaining. "The curses will go first and then you'll all go. That's how I planned it. "

"Are you certain that Sukuna will be there? " The contestants of the final team asked.

"Of course, Angle. Once you find him, he's all yours." Geto said making Kashimo release a burst of electricity to the girl.

"I'm the one who will fight Sukuna. " They both stared at each other.

Geto quickly clapped his hand and said. "You can sort it out in the Domain. "

"What about you Geto? You're not going in? " One of the curse users asked.

"I'll go in later. After everyone has already killed each other on the first layer. " Geto answered with a smile.

"What about your team? " Uro asked.

"I'm by myself. Unless I find someone who I want to go with." Geto answered with a devious expression.

The group of curses walked around looking for Ainz until a great pillar of light emerged from the streets. While every other street was full of people in costumes walking around partying it up, there was one empty block.

Ainz stood in the middle of the road patiently waiting for the clock to strike midnight.

All of the curses who were part of Geto's teams immediately jumped and quietly waited. They had another 30 seconds before it started.

The jujutsu sorcerers got there just a few moments afterward. Gojo, Yuta, Yaga, and Gakuganji all stood in front of their teams while they eagerly waited.

Gojo turned at the curses and immediately turned his head away. "Look at them. Disgusting! " Gojo said as covered his nose. "Hey it's the weak one. I see you got your body back."

Jogo's eyes widen before he prepared a fireball on his hand. "This is a no-combat zone. I hope you'll leave the fighting after the game has begun. " Ainz said. Jogo mumbled something before focusing on Ainz.

20 seconds until the game

"Hey, AInz. Can't wait to get to you. " Gojo said while trying to get Ainz's attention, but the overlord chose to ignore him.

"So this is the curse that beat you up, right sensei?" Yuta said as he examined the famous death curse.

Gojo quickly turned to Yuta saying, "It was a-"

"Draw. We heard that already. Shut up, Gojo. " Yaga said as he tried to concentrate on the mission.

10 seconds until the game

"To think so many Special Grade Curses even existed. " Gakuganji said as he warmed his fingers by playing some minor chords.

"Right?! That's crazy. " Nobara said as she grabbed a handful of nails in her bag.

"I hope you treated my brother, Itadori Yuji, really nicely or else- " Todo was about to talk some shit to Ainz before the overlord raised both of his arms.

Everyone stopped talking and immediately prepared for the game to start. Ainz snapped his fingers creating a huge throne behind him.

The overlord slowly and elegantly sat down. He placed his elbow on the armrest and then rested his head over his hand His eyes flashed red which made everyone cover themselves in a thick layer of cursed energy.

"Some of you are here for selfish reasons... some of you are here because you think you can save the world. " Ainz spoke making everyone even tenser. "It does not matter. In the end, we either get what we want or we don't."

"That's what we are here for and that's what were are going to find out. Curses, humans... we put an end to this stalemate and finish this once and for all. "Ainz's voice echoed around the street. Everyone who was below special grade felt a cold sweat running down their backs while the others became just a bit anxious.

"I wish you all good luck and may the strongest thrive. " Ainz said before his cursed energy spiked to an even greater level.

This was the first time in jujutsu history that an entire continent was filled with cursed energy. It caused all the electric equipment to shut off for a few seconds before rebooting. The non-sorcerers felt a sharp headache followed by nausea.

That final portion of the speech was the final words they heard before the dreaded chant. Everyone already knew this was coming, but hearing it in person still made their hair stand up.
