Bony Boy goes to JJK World

Hey, there. Author here. Someone noticed that the chapters are getting shorter and yes you are correct. I have been working considerably more than when I first started and thus I don't have that much time to write the story. To continue the uploading schedule the chapters suffered a cut in their length. Sorry.

P.S.: Writing is hard, okay? XD. It takes time and you're mentally tired in the end. I'm new at this so don't judge me so harshly. XD

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


Sukuna's pov

"I see. So this must be where those gladiators used to fight. It does feel like a proper place for combat. " Sukuna said as he walked into the amphitheater's main area. Both Mare and Aura were nowhere to be found, but Sukuna didn't mind the fact that he couldn't find the guardian right away. He simply marveled at the location where humans used to do battles against each other. "Though I doubt maggots that couldn't use cursed energy needed this much space for combat. Was it this spacious just so that the other pathetic creatures could watch? " Sukuna asked himself as he turned his attention to the stands.

"Mare, I'll go first. Don't forget to buff immediately after we land there. " Aura said while she watched Sukuna walking around the arena. He had both of his hands in his pocket and had a relaxed stance, but Aura could tell that it was just a front for the perverse and cruel nature of that man.

"Y-yes, Sister. " Mare said right before nodding to his sister. He tried his best to remain calm and collected so that his sister wouldn't worry or feel as if Mare couldn't fight properly, but the clutch of his hand on the staff told Aura everything she needed to know. Mare was getting scared to fight the intruder.

'That guy is something else entirely, even when compared to the man who was here just a few moments ago.' Aura thought as she jumped from behind the stands in the VIP section. Mare quickly followed her and both of them landed just a few meters from Sukuna. The king of curses turned to them slowly while unleashing a terrifying amount of bloodlust only to stop as soon as he saw them.

"Kids? In the form of a cursed spirit? What type of joke is this? " Sukuna asked as he tried to annoy the guardians just as much as they just annoyed him.

'Shit. They are quite strong. This is going to take as long as time. ' Sukuna thought to himself while he pulled both of his hands out of his pockets. Mare immediately started buffing Aura as much as he could. Aura pulled her bow from her inventory and called upon her pets to help.

'This guy... I can't tell what his level is. ' Aura thought as she watched Sukuna just stand there allowing them to buff as much as they wanted. He also allowed Aura's pets to surround him and even attack him before he finally reacted.

'Killing them one at a time is a good and fun strategy. I must have at least 16 hours left before the game ends so there's no need to force things too much. ' Sukuna thought as he let one of the insect-looking creatures jump toward him. Having a lot of time would allow him to play with his food and also get into shape once again, but there was also the problem of Itadori taking over the body at any moment, which meant that he didn't have the full 18 hours that were left. 'Still, I don't like that these two think these small weaklings present any sort of challenge to me.' Sukuna thought as he moved his right arm to the side before making a line with the palm of his hand.

[Cleave]

The imaginary line that he drew passed right through the cursed spirit and just a few moments after Sukuna did the motion, a huge cut appeared in the cursed body. The creature was sliced right where the line would be overlapping its body and soon after the curse disappeared. 'I saw something and then... He killed my pet in one hit?! ' Aura thought as she immediately order the others to stand back for a moment.

Aura pulled the string on her bow as she tried to recreate the same weird phenomena that she was able to copy from Yuki's attacks. "Simple domain? Look at that, the curse is using party tricks. Well, I guess that would be useful against that idiot's barrier so I don't blame you for using it against me. " Sukuna said as he showed his devilish smile.

"Old man, you talk a lot huh? " Mare said as he popped his head from behind his sister's back. "I wouldn't be so confident if I were you. " Mare continued talking which made Sukuna lift one of his eyebrows.

"Thank you for your concern, but I don't think I need stupid kids advising me. " Sukuna said.

He barely had enough time to finish his sentence before Aura finally was able to form a layer of mana around her body. She then released the bowstring. Sukuna was taken aback for a moment as he saw an arrow appear out of nowhere on the bow just as Aura released the attack. 'Creation type cursed energy? But I didn't come from the guardian. Was it the cursed item? How interesting. ' Sukuna thought as he saw the arrow rush toward him at blinding speed.

But, just as Aura had predicted, Sukuna was easily able to deflect the arrow by simply smashing the back of his hand on it. His hand ended up being cut slightly, but thanks to his reversed cursed energy, Sukuna was able to heal in just a fraction of a second. 'He has a lot more mana than the last guy, plus he can also heal by consuming mana. His spell can once shoot my pets and is so fast that I could barely see it being cast. There's no mistake, this intruder is above level 100. ' Aura thought as she concluded the initial estimation of Sukuna's power.

Aura then quickly pulled back on her bow's string and unleashed a second wave of the arrow, but Sukuna quickly shot them down by using his cursed technique. He drew another line that spanned both the four arrows that were going toward him and Aura herself before releasing his power.

"Sister! " Mare screamed as he saw the arrows being cut in mid-arrow right before Aura suffered the same fate. Aura was about to hit the ground, but her pride as the guardian of the sixth layer forced her to spread her stance and stay up. Aura failed to move away from the spell and her left shoulder paid the price. The bow almost fell to the floor as Aura's grip slowly became weaker.

[Heal]

The cut ran across her entire width and you could see through Aura's shoulder. Her left arm was left dangling with just a few strands of muscle holding it together, but Mare's spell quickly fixed it. "I meant to cut your arm off with that attack. Congratulations, you are stronger than I thought you would be. And you too, your use of cursed energy to heal is amazing for someone with so little power." Sukuna said as he started to clap.

Mare quickly turned his head to Sukuna who had a big condescending smile on his face before saying, "Old man, I'm the one who should be congratulating you on being able to damage my sister, but this will be the last bit of damage that we will take from you. " Mare said in a serious and calm voice.

"Ha ha ha. Really now? " Sukuna asked as he started walking forward with his chest puffed out and a huge smile on his face. Sukuna could feel as Mare's cursed energy rose alongside Aura's which could only mean that the real fight was about to begin. "Then show me. " Sukuna said right as his body was crushed by a massive stone hand that popped out from the ground underneath him.

"Primal Earth Elemental, crush him. " Aura said as she pulled the string on her bow back. She knew from the previous exchange that Sukuna would not be killed by that attack and even if he could be, there was still the possibility that he would use a barrier similar to that of Gojo's. That was what lead Aura to throw a huge attack at the summons hand.

[Targeting Skill]

Just as Aura unleashed a huge amount of arrows toward the elemental, Sukuna used his cursed energy to burst out of the summon's grip. "That's it for your shikigami? You're making embarrassing me. " Sukuna said as he performed his cursed technique and sliced through the elemental in a single moment.

Sukuna then turned his attention to the dozens of arrows making his way toward him. He then performed a different motion with both of his hands together.

[Dismantle]

All of the arrows were sliced through from the point to the nock. After that, they were sliced through again, but in a different direction. This continued repeating itself until the arrows turned to dust. "The arrows... " Aura briefly took her eyes away from Sukuna to focus on figuring out what type of spell he had just used.

Sukuna quickly noticed that Aura was distracted and he moved to attack her. He closed the distance before Aura could react to his approach and punched her in the face. "Was Dismatle that impressive for you? Ha ha ha. " Sukuna asked as he chuckled a bit.

Aura was thrown backward, but before she moved too far back, Sukuna grabbed her by the feet and threw her upward. He then quickly followed her before delivering another punch to the face. "S-sister! " Mare said.

[Magic Shield]

'So the one with the skirt is the support type... This is troublesome. ' Sukuna thought as he continued to punch Aura for a bit before deciding to use his cursed technique once more, but just as he expected, the moment he placed his arm to the side and gathered the cursed energy to use it, Aura came back to life. She quickly placed her bow back into her inventory and pulled out her whip.

[Cleave]

Sukuna then drew another line, but this time Aura used the whip to hit the area right in front of her. 'Smart. ' Sukuna thought as he knew what Aura had in mind. Thanks to her whip being covered with simple domain, she was able to dispel the cleave attack and created a safe zone around herself. Aura was pushed back by the cursed energy that belonged to the technique, but she was not cut.

[Triple Maximize Magic: Call Greater Thunder]

Mare quickly retaliated with a spell of his own. Sukuna was engulfed by lightning which immediately paralyzed his body for a few seconds until he inevitably got used to it. 'A direct attack cursed technique? Was I mistaken about that kid or... ' Sukuna covered himself in cursed energy and prepared to counter whatever they were planning to throw at him once the lighting passed.

However, even before the spell ended, Aura sent out another volley of arrows which Sukuna couldn't even perceive. As soon as the spell disappeared, Sukuna saw the arrows that were just a few meters away from him so he immediately attacked.

[Dismantle]

[Shadow-piercing Arrow]

The arrows were once again turned to dust within just a few moments. Sukuna turned to the twins with a huge prideful and condescending look, but before he could taunt them again, he felt his body freeze up. 'I can't move?! ' Sukuna asked himself just as Aura pointed at an arrow that was lodged into Sukuna's shadow.

"Sorry, old man. But this is it. " Aura said as she released another volley of arrows toward the king of curses. Sukuna tried to move away from the attack but his movement didn't return in time and he was hit by them.

'My cursed energy output is going down! What kind of cursed technique is imbued in these arrows. ' Sukuna thought as he felt his strength being drained from his body. Of course, his power was not being taken away from him. It was just being sealed for a few minutes as the debuff was applied.

[Triple Maximaze Magic: Hellblaze]

A huge tower of cursed black flames erupted from the ground and engulfed Sukuna. Aura quickly began shooting more arrows toward Sukuna as she wanted to finish the fight as soon as possible.

[Triple Maximaze Magic: Hellblaze]

Mare used the same spell once more causing even more damage to Sukuna who was still unable to move. At one point, Sukuna fell to the ground, but that didn't stop the twins, who continued to strike at him with all their might.

Both of the guardians continued spamming attacks toward the king of curses until he was finally able to move. Sukuna used his cursed energy to propel himself to the side which allowed him to dodge the final cast from Mare. His body was completely burnt and for the first time in his existence, he felt regret. Yes, regret. 'I underestimated these guardians and by extension, Ainz. ' Sukuna thought as he began healing himself.

Both Mare and Aura were still thinking that Sukuna was on the same stop and thus they attacked it which bought a few seconds for the king of curses, but healing was taken longer than he anticipated. 'That fire was not normal. It must have been imbued with a special from their cursed energy. ' Sukuna thought as he noticed that it was faster to take off his body parts and heal afterward than it was to try to regenerate the burnt parts. 'It's just as I thought. They know about it. '

Sukuna slowly got up before looking at where he believed the twins were. He then placed both of his hands together.

[Open ■ ]

He then pulled his hands away from each other producing some type of flame between them. 'Those dammed curses. ' Sukuna thought as he aimed right at Mare before releasing his flames.

Sukuna controlled the flames as if he was using a bow as he unleashed the attack in the form of an arrow. Mare, who had just figured out that Sukuna had escaped their most recent attacks, moved to the side trying to avoid the flaming arrow. "He's using ranged magic, sister. " Mare said as he left the arrow's line of attack only for it to turn toward him.

"It's a homing spell! " Aura screamed as she turned her attention to Sukuna who without a doubt would take up the opportunity to strike again. She immediately felt disgusted by what was left of the king of curses. His face was half melted and his jaw was hanging open. It was obvious that he only bothered to heal the most essential parts to continue the fight.

Aura immediately pulled her bowstring once again, but Sukuna was even faster. He unleashed another one of his flaming arrows just before Aura could use one of hers. 'There's no question that the attack is supposed to be powerful, but is he still under the debuff?' Aura asked herself thinking that she could trade hits with Sukuna, but unknown to her, the debuff that should have lasted for a good 2 seconds per arrow, was actually only good for a quarter of that, meaning that Sukuna returned to his normal self moments before throwing the first flames.

Sukuna quickly ripped out his own jaw before throwing it to the side. He then grew a new one within moments. 'The debuff ran out! ' Aura thought as she quickly began firing her arrows at the flames themselves and since Aura's attacks were coated in a simple domain, the technique was invalidated allowing Aura more than enough time to dodge the pure cursed energy that was now rushing toward her.

Mare, however, was not so lucky. He got hit by the flaming arrow and was pushed to the ground immediately after. The flames were not only burning him from the outside but also from the inside as the attack pierced his entire body. "Argggg! " Mare winced in pain making Aura turn her eyes toward him.

"Mare! " Aura took one step toward her bother before she felt Sukuna's cursed energy rise up.

"This was supposed to be fun, you know. But it's not doing it for me anymore. " Sukuna said in a serious and ominous tone. He then placed both of his hands together and produced the same flames as before.

Sukuna threw another arrow toward Mare who was still on the ground struggling to heal himself. The flames were somehow maintaining themselves even without oxygen as they spread within his body which made it extremely hard to extinguish and mitigate damage. Aura quickly dispelled the attack with her own arrows before she rushed Sukuna who immediately placed both of his hands together.

[Domain Expansion: Malevolent Shrine]

Moving away from Mare proved to be the worst mistake Aura committed. Sukuna's domain was unique in that he didn't create a wall, which meant that the range was huge for balancing proposes. Therefore, both Mare and Aura were caught in it. "For every cursed spirit in range. Cleave. " Sukuna said right as he finished casting the domain.

Aura didn't know what a domain was but to use it in this way and with this amount of confidence at this point in the fight, there was no way that the attack was not some sort of trump card. She immediately turned to Mare whose body began to be cut in several pieces."S-s" Mare couldn't even say goodbye as his body was cut into million pieces. Aura's pets were also cut in the same way and after a few moments, only Sukuna and Aura were left standing.

"What... Mare..." Aura was left in shock for a second before she finally turned her attention to Sukuna who was also left in shock.

"You survived my Domain by using just a simple domain? " Sukuna asked as he created the same fire he was using before. "Impressive. "

Aura quickly pulled her bow and fired a bunch of arrows, but Sukuna was, once again, faster than her. He unleashed the arrow toward her once more and Aura was forced to dispel it again.

But this time, after being dispelled, the arrow returned to its fiery self and continued pursuing the target. Aura couldn't believe what happened and so she tried it once more while she retreated and the same thing happened again. "As long as the arrow is in my domain, the technique can be reformed. It's pointless to dispel it. " Sukuna said as he watched Aura giving up on trying to block the attack. She finally noticed that while she was not cut, she got hit so many times with the pure cursed energy from Sukuna's domain that now Aura couldn't outrun it.

Aura fired a final arrow before being hit by Sukuna's attack. She then fell to the ground just like Mare and since she couldn't heal with her magic, Aura was left on the floor. 'Damn it. we lost, Lord Bukubukuchagama. Lord Ainz. Sorry...' Aura thought as she felt the end was near.

[Dismantle]

Sukuna moved his fingers as he sent out an attack toward the arrow. He then quickly moved his hands creating a line where Aura was. That, however, was not enough for Sukuna whose pride was injured thanks to her.

[Cleave]

Aura could no longer maintain her simple domain protection and thus she was cut.

Sukuna wanted to continue attacking until he felt satisfied, but when Aura's body disappeared, he was forced to stop. "Ha ha ha. What am I doing getting so worked up with inferior creatures like cursed spirits anyway? Sure, these two had some real understanding of cursed energy if they could pull off multiple types of techniques, but they can't grow beyond that. They are just cursed spirits at the end of the day. " Sukuna said as he tried to calm himself down.

A huge door that would lead to where the champion of the arena would emerge from opened revealing the entrance to the next layer. Sukuna took a deep breath before sitting down. "Good, now where the hell is Kenjaku. " Sukuna said.
