Chapter 16: Vacation in Another World!

__________________________________________________________________________

- Felix -

"Domain Expansion: Unlimited Void!" "Malevolent Shrine!" 

"Huh?!"

I immediately activate Thought Acceleration causing the world to look like it has almost stopped in order to process what is happening and when I just showed up.

What the fuck?! Is that Sukuna in Megumi's body? Gojo is unsealed? Looks like a ton of stuff has happened since Gojo was sealed. Man I really wish I could have finished Jujutsu Kaisen, maybe then I'd have an idea on what the fuck is going on.

It seems like I showed up in the middle of a Domain Battle between Gojo and Sukuna, one that Gojo won since it looks like Malevolent Shrine is collapsing.

Now why am I not being affected by Unlimited Void's sure-hit attack?

'Answer. Domain Expansions sure-hit attack only affects those with Cursed Energy , someone like Toji Zenin would not be affected by a sure-hit attack, and since the Master does not possess Cursed Energy, it does not affect you.'

'I see, it's a good thing you have access to my memories or I'd be screwed. How does Cursed Energy work? It seems odd that the Cardinal World has one form of energy, and then all these other worlds have other forms of energy, do you have any explanation for that Odin?' I might as well ask all my questions seeing as not even a millisecond has passed in the real world yet, I have all the time in the world.

'Upon entering this world, it was detected that a filter was placed over it by The Voice of the World. This filter was likely placed due to the wishes of the True Dragon Veldanava, in hopes that there would be more variety in the various worlds he had created.'

'I see, so this filter is what allows all these different supernatural energies to exist?'

'Correct, the filters convert Magicules into different forms, so the roots of all these different energies can be traced back to Magicules.'

'I see, that's quite interesting, since there aren't any actual Magicules in the air, how will Magicule Breeder Reactor function?'

'Since Cursed Energy's origins can be traced back to Magicules, Odin can convert Magicules into Cursed Energy, and vice versa after analyzing the filter places over the world.'

Woah! Now that's something! 

'So can you change Magicules into basically any energy as long as that energy comes from Magicules in some way?'

'Correct, as long as Odin can analyze the filter in question, it should be possible to convert Magicules into the energy said filter is responsible for.'

'Damn, that's badass, nice work Odin.'

'Query, can Odin change some of the Master's Magicules into Cursed Energy in order to analyze the technique known as Domain Expansion: Unlimited Void?'

'Will there be any side effects on me? I'm not sure if even I am capable of brushing its effects off.'

'Answer, Odin will take care of all of it.'

'I see, I trust you Odin so go for it.'

I feel some of my Magicules turn into a different energy, though one not entirely dissimilar from Magicules. I remember that Cursed Energy's foundation lies in negative emotions. Now that I know what to look for I can feel the Cursed Energy all around me.

And all of a sudden I was bombarded with what felt like infinite information.

'Notice. It has been detected that the Master's mind has been overloaded with 7,884,000 seconds of information in one tenth of a second. Odin will divert the information to eight Parallel Operations, and then analyze the ability.'

I immediately reactivate Thought Acceleration in order to process what just happened.

So that's how it feels to have a bunch of information just shoved into your head, not a fun feeling, it looks like Odin had to lower my Thought Acceleration for a moment, but I did give her permission to do whatever.

'So what did you figure out Odin?'

'Notice, Those affected by Unlimited Void have all the actions one has taken throughout their life forced upon them over and over, causing the target to become immobilized as they are incapable of processing such a vast amount of information.'

'I see, that matches what I remember hearing from my first life.'

An ability like that would prove troublesome even back in the Cardinal World, though that's only on the condition that it works on those without Cursed Energy .

I expand my senses to figure out what is going on outside the Domain Expansion and am not surprised when I find numerous individuals in an observation room of some sort. A fight like this, one between the two strongest beings in this world, though they aren't the strongest anymore seeing as I'm here now, is bound to be observed by numerous third parties.

Even further than the observation room I can feel a barrier locking everyone into this area, with nine others just like it all around Japan. They seem to be connected to each other through barriers that also act as a sort of boundary.

I can feel tons of Spirits made up of negative emotions all around everywhere too, those must be Cursed Spirits. Part of me is curious and wants to kidnap one and take them to the Cardinal World. I wonder how they would evolve if I named them.

But still, these Jujutsu Sorcerers seriously let them get out of control. I can feel a ton of them all throughout Japan.

That isn't all, Shibuya has basically been erased off the map. 

Seriously, what the fuck is going on? 

And then there is a barrier surrounding all of Japan, I can feel it drawing in the Cursed Energy from all around the planet and focusing it all into Japan.

That must be the reason Jujutsu Sorcerers are so uncommon abroad, Tengen made it that way.

The barriers shouldn't be a problem for me to deal with.

Along with that, while I don't sense any Magicules, I can sense Spiritrons which isn't surprising. Spiritrons are the building blocks of spiritual matter like Magicules, Aura, Holy Power, and it seems Cursed Energy as well. 

'Query, may Odin take control of one of the master's Body Doubles to conduct detailed analysis of the surroundings?' 

'Ah, you're talking about the skill Body Double right?'

'Correct.'

'Will I still have access to you when you are in the Body Double?'

'Yes, Odin is capable of utilizing a Body Double, and being available to the Master if necessary, however the further the Body Double goes from the Master, the less abilities the Body Double will have access to.'

'I see, so it's kind of like wifi, the further away you go from me, the less of your abilities you have access to. Alright, then go for it.'

I gained access to the Body Double Skill through Moss, his Unique Skill has Body Double as a subskill.

I watch as Odin creates a Body Double with 20% of my total magicule capacity, the Magicules I'm spending on the Body Double can't be regenerated with 'Magicule Breeder Reactor', as the Magicules used in the creation of a Body Double is the amount of Magicules the Body Double has access to. I'm basically splitting off a portion of my power and giving it to the Body Double to use.

The resulting Body Double looks just like me except, with red eyes, and a far more expressionless face.

Body Doubles are capable of using all the Arts I have access to, along with my lower level skills, and since Odin is the one piloting the body, she is capable of using all her abilities through the double if at a lesser extent than what she is normally capable of.

Thought Acceleration, and Parallel Operation for the win!

Odin seemed excited, it seems even she wanted to see what was up with a new world.

Once Odin leaves I lower my Thought Acceleration as I'm flying high up into the sky in order to get a better view. I'm curious how a fight between Gojo, and Sukuna will go. My presence is still completely concealed so no one should be able to detect me unless I allow it. I even put up an illusion to hide my form just in case.

I bet Gojo is likely to win seeing as he is basically the Protagonist of Jujutsu Kaisen, my man literally carries the entire series.

Sukuna isn't a fool either though, he wouldn't be fighting head on like this if he didn't have a plan. I wonder how he is going to get past Infinity, his Domain Expansion's sure-hit effect will work, but that's only if Gojo let's Sukuna deploy his Domain without any countermeasures.

I watch as Gojo rushes at Sukuna while he is still being affected by Unlimited Void, is this it?

All of a sudden a Shikigami of some sort appears in front of Sukuna, it seems even Gojo is wary of this Shikigami.

It's likely one of the Shikigami from Megumi's Ten Shadows. I wonder what that wheel on its back signifies? 

Oh? It seems Gojo is going to attempt to take it out in one shot.

"Cursed Technique Reversal." 

Unfortunately before Gojo can cast Red, the Shikigami interrupts him. How odd, shouldn't it be affected by Unlimited Void?

"What?!" Even Gojo is surprised.

"Megumi's Soul!" Hmm?

"Oh? It looks like you have something on your mind."

They ended up trading jabs back and forth before getting to what I was really interested in.

"Unlimited Void, an ability that activates once inside your Domain… Honestly, I figured it was going to be a real pain." This guy is acting rather smug for having to use external means to escape Unlimited Void.

Though I guess that is a power on its own. He hijacked Megumi's body so he gets its abilities.

I do wonder what is so special about the 'Ten Shadows' for someone like Sukuna to desire it though.

"That's why my first move was taking it out of the deck, while unable to use amplification in the Domain, I had Fushiguro Megumi adapt to Unlimited Void using his technique."

Huh? You can adapt to a Domain Expansion?!

"All he took was the process of adaptation, not the result of it right?" I'm completely lost.

'It is likely that the individual known as Sukuna pushed the strain of Unlimited Void onto the soul of the individual he is possessing, allowing him to use an ability of some sort to adapt to Unlimited Void.''

I see, now how the hell was he able to adapt to a Domain Expansion? If it can adapt to other things as well, then that just sounds absurd.

If someone got a Skill like that in the Cardinal World, they are basically guaranteed to become someone of renown as long as they don't fuck up and die before they adapt to basically everything.

Now I'm really curious about this new ability of Sukuna's.

"Sukuna, you haven't actually adapted Megumi's soul to Unlimited Void, If I open my Domain again, Mahoraga won't be able to bail you out. I'll destroy you in one attack!"

So the Shikigami's name is Mahoraga. Could that Shikigami be responsible for this whole adaptation thing Sukuna has going on?

"Kukuku." Ah! He has the Diablo laugh!

"You can no longer open your Domain. Using Reverse Cursed Technique to heal your exhausted Innate Cursed Technique, you've been using Cursed Energy to damage your brain, and then refreshing your brain with Reverse Cursed Technique. You've reached a limit different from the physical, if you expand your Domain you will die the moment you do so, not to mention that it will be far too weak to affect me."

"I'll close my Domain now and carve you to pieces, I'll even adapt to that Infinity of yours." That's possible?! Is that wheel on Sukuna's back responsible for his adaptation?

"Domain Expansion." It seems like I'll have to step in.

Oh? His Domain isn't expanding.

'Notice. It is likely that the individual known as Sukuna took a blow from Unlimited Domain for a fraction of a millisecond causing his brain to sustain enough damage to make Domain Expansion impossible.'

'I see, thanks Odin. Without you I'd be completely lost here.'

It seems they are going to fight in pure hand to hand combat now that they both can't use their Domains.

I wish I had some popcorn, this is entertaining.

They are both kinda sorta strong, for this world they are probably unbeatable, in the Cardinal World though…. Well they are just slightly bigger bugs. 

Oh? The wheel on Sukuna's back is turning.

"You need four spins total, yeah? That leaves three more." So the wheel needs to spin four times in order to adapt to something then. "Three more spins of the wheel until Mahoraga adapts to my Infinity." So the adaptation ability isn't Sukuna's, rather it is Mahoraga's.

Theoretically Odin should be able to delay Mahoraga's adaptation if not completely negate it with the subskills she gained from Usurper.

"Hehe, I got three more spins to beat you up then."

Ah yes, the mutual shit talking mid fight is always great.

It's no wonder Gojo Satoru is considered the fastest man on the planet, no amount of speed can beat rapid teleportation like what he and I can do with Blue.

But speed alone isn't enough. 

"Gashnk" Only two more spins until he adapts now.

….

….

One more spin left.

Not even Red was able to deal with Sukuna, though it seems like Gojo has a plan in mind seeing as the Red he just fired hasn't detonated yet. It looks like Sukuna used Domain Amplification to minimize the damage Red initially dealt to him.

"Such sloppiness, lost your cool after your hand was revealed?"

Ah, I know that grin Gojo has, it's the grin I have when I fuck with someone.

"You know, that Red just now didn't explode."

Ah I see.

That's a smart move, using the building layout to his advantage.

BOOOM

Gojo had Red hit Sukuna from behind after taking a full loop around the building, and it looks like his plan worked.

Oh? And Gojo landed a Black Flash on Sukuna as well, that's gotta hurt.

Black Flash basically increases someone's control over Cursed Energy temporarily and multiplies the output of an attack, something that Odin is capable of doing quite easily with my Skills and its own perfect control over Magicules.

It's due to the increase in control over Cursed Energy that it is said that using Black Flash draws out 120% of your potential, it leads to a greatly increased performance in combat.

It looks like Sukuna is going to need some more help to get out of this one. 

At least I will get to understand Mahoraga a bit more now since Sukuna just summoned him again.

"Phase, Pāramitā, and Pillar of Light. Cursed Technique Reversal!" He's even using the chants now.

Oh? Mahoraga is on the offense and isn't being affected by Infinity, it seems it was able to adapt to it.

'Is there a way for you to analyze that ability and give it to me Odin?'

'Notice. It is recommended that the Master consumes the entity known as Mahoraga with Beelzebuth.'

'I see, having any level of adaptation will be useful so I'll watch the fight for a little bit longer before consuming Mahoraga.'

This fight was getting boring to watch anyway. At this point I'm just curious about what other abilities these two are going to pull out.

It looks like Fortunate One worked its magic by making me appear at this very moment, setting things up so I will have the opportunity to acquire that adaptation ability.

While Mahoraga is on the offense Sukuna is on protection duty making sure Gojo doesn't permanently deal with Mahoraga.

Did he just throw a fire extinguisher at Gojo?

Well, he's gotta do what he's gotta do I guess?

Oh? Is he compressing water into an attack? Man if that hits it's gotta hurt.

'Notice, the fired water beam is capable of reaching the speed of sound due to being reinforced with Cursed Energy .'

The speed of sound?! That's impressive, it isn't a threat to me seeing as I am capable of moving at close to light speed with perception that far surpasses that, sound moves at about 340 meters per second, while light moves at 300 million meters per second, they aren't even comparable. But in a world like this, I bet it's damn near impossible to avoid by anyone other than those at the top of this verse.

Gojo wasn't even able to avoid the attack either since Mahoraga had erased Gojo's Infinity allowing Sukuna the perfect opportunity to land a hit.

That Shikigami of Sukuna's is basically another opponent.

Gojo is seriously getting ganged up on.

"Haha! Don't misunderstand, this isn't a 2-on-1, it's a 3-on-1! Nue. Totality."

Gojo might be in serious trouble here, but I do want to see how this fight is going to go, just out of pure curiosity at this point.

Raiden, and Kurumi should be fine as they are inside of my Stomach. I even set it up to where they can view a projection of the outside world through my eyes so they aren't bored.

Gojo is doing quite well for taking on three opponents at once. "Red!" 

Oh? That was a direct hit, and yet Mahoraga seems to barely be affected by Red. He only took one hit from Red head on earlier and has already adapted to this extent. That means that the adaptation is likely done gradually.

If he wants to take Mahoraga out he has to do it in one hit before Mahoraga starts to adapt. Hollow Purple should be able to deal with it, the only problem is actually landing the attack.

Sukuna's newest summon, Nue I think is its name, has a few abilities. It can fly which can be useful in this world since it isn't as easy to fly here as it is in the Cardinal World. An aerial advantage has the potential to be deadly depending on both parties' strengths. It's what Frey is known for after all. It also has purple colored electricity that should be capable of stunning the opponent. 

Shikigamis might be the way to go in this world, there are so many of them, and they all have useful abilities. Though I guess that's only on the condition that the user has the Ten Shadows Technique, or else I bet it would be a lot harder to get such useful Shikigami.

"Gashnk."

And that's an arm gone for Gojo.

It seems Mahoraga has some slashing ability, similar to what Sukuna used to kill that Special Grade Spirit that had one of his fingers early on in the series. I would step in now, after all I don't want Gojo dead, I like his character, of course he may be different in real life, but I have a positive impression of him at the very least. However it seems like he has a plan of some sort and I want to see what he has in mind.

Gojo turned towards Nue, "You know, I've been thinking. You just don't fit in with this crowd. Maximum Output Blue!"

And there goes Nue, Gojo even managed to land another Black Flash. This fight might not be anywhere close to my level, but it is still kinda fun to watch, sorta like watching two children fight each other with sticks.

Huh? Am I becoming arrogant? Nah, it must be my imagination.

'....'

'Did you say something Odin?'

'Negative.'

'Weird.'

"Phase. Pāramitā. Pillar of Light. Cursed Technique Reversal."

"Mahoraga!"

So that's his plan, to merge the Red he just fired with the 'Blue' he fired earlier when he took out Nue, in order to create Hollow Purple. That's a good idea, it can definitely catch your opponent off guard. I'll have to remember that if I ever have to go to such lengths to win a battle, then it will definitely come in handy.

Sukuna ordered Mahoraga to prevent the Red, and Blue from colliding, but its adaptation will backfire on it if Gojo plays this right.

It seems like Gojo is going to use the attractive force of Blue to give a boost to his speed, and get in between the Blue, and Mahoraga. Now with Mahoraga out of the way it looks like Sukuna is getting slightly desperate. He's even recycling old moves by sending that water beam at 'Red' in the hopes it detonates early.

"Too slow." Yikes, Gojo just barely missed the opportunity to prevent Sukuna from firing his water beam.

"Phase. Twilight. The Eyes of Wisdom." It seems he will have Blue activate to swallow the water beam, that's a good way of dealing with the attack.

"Nine Ropes. Polarized Light. Crow and Declaration. The Gap Between Within and Without."

Here it comes, I've done this so many times myself, but I always find myself excited when using this move. Even if mine is far superior to Gojo's due to the difference in power between us, this will still be enjoyable to watch.

I could feel a grin on my face as I heard Gojo say, "Hollow Technique: Purple."

I'm glad I didn't interrupt this fight, watching these two fight for their very lives is amazing. I'd feel bad if I interrupted earlier, I'm sure these two are having one hell of a time.

'Notice. There is a high chance that the Hollow Purple that the individual known as Gojo Satoru fired will destroy the entity known as Mahoraga, it is recommended for the Master to protect, or consume Mahoraga now.'

'Got it, might as well make one hell of an entrance then.' 

I stop concealing my presence, as I start to release my own Aura slightly, not enough to spawn monsters, but enough to show that I mean business. I also get rid of the illusion covering my physical form. I quickly appear in front of Mahoraga at a speed most aren't capable of following. In this world I don't think there is anyone who can follow my movement.

It seems like both Gojo and Sukuna are aware of my presence now as they are looking at me in shock. Unfortunately they are far too late to do anything about it.

I grab Mahoraga by the neck and teleport out of the blast radius of the Hollow Purple Gojo just created.

All of that took place within 0.5 seconds.

Hollow Purple is known for being able to hurt the caster in certain circumstances, as well as the surroundings, and the Hollow Purple that Gojo just fired was far stronger than his standard Hollow Purple, it's likely that even Gojo was hit by his own Hollow Purple as this was an omnidirectional blast rather than a directional one. 

Once the blast settled down I could see that Sukuna, and Gojo were both heavily injured. I'm surprised that Sukuna was able to survive that Hollow Purple. 

Sukuna was leaning against a wall, while Gojo was barely able to stand upright, but both of them were staring at me.

I decide to deal with Mahoraga first, seeing as I don't want to take any chances with it. 

"Beelzebub." Beelzebub sounds far better than Beelzebuth, I might as well live out my chunni fantasies now that I have the opportunity to do so. I watch as Mahoraga is devoured in a purple whirlpool.

Now Odin should be able to analyze Mahoraga's abilities. I don't think I will get any Skills out of it until I return to the Cardinal World seeing as Skills are only rewarded in the Cardinal World. Maybe if Odin becomes capable of making Skills on her own then I'll be able to gain Skills in other worlds, but for now I have to hope that The Voice of the World will reward me with an Adaptation Skill when I return.

Theoretically it should give me a Skill for Adaptation seeing as it can hand out Skills based on how proficient you are in something, and since Odin has all the Data on Mahoraga's Adaptation, it should be enough for The Voice of the World to recognize.

Now that Mahoraga is dealt with, what should I do now? I'm leaning towards sticking around and fucking with these two since I've already derailed their fight.

I start clapping as I descend towards them, "Ghahaha, what an interesting fight you two!"

- Gojo Satoru -

He was proud of himself for that Hollow Purple improvisation, he even regained his Reverse Cursed Technique from the Black Flashes he landed, he truly was the strongest. Sukuna is down a Mahoraga, has slowed healing, and can't do any damage to him without Domain Amplification. Things were really looking up for him before this guy showed up.

He stared at the mysterious newcomer as he tried to think if he had heard of someone like him.

"Is he one of yours?" Asks Sukuna, it wasn't that surprising that Sukuna was able to survive his Hollow Purple, but a man can hope.

At least it looks like he's on his last legs, he was also able to get Mahoraga with that Hollow Purple, but this new guy might just be more troublesome than Mahoraga, or more fun than Mahoraga.

"No, never seen him before." Maybe he was sent by one of the surviving higher ups? Could he be one of their hidden cards? No, with all the stunts he has pulled in the past they would have used this Sorcerer to pressure him into compliance, hell they probably wouldn't all be dead if they had someone like this in their back pocket.

So a completely new variable. Maybe one of the new Jujutsu Sorcerer's that Kenjaku created, or one of the ones from hundreds of years ago that incarnated in the modern era. Since he has an Infinity of his own up, it's more than likely he's a Gojo from the past if that's the case. Though for him to be able to use it at all despite not appearing to have Six Eyes shows unfathomable levels of skill.

His facial features increase the likelihood that he is from the Gojo Clan, with his white hair, and blue pupils, but he hasn't heard about anyone like him from the Elders or the clan archives, and they aren't foolish enough to hide information on someone like this man from him, the Clan Head.

And then there was his black sclera, that definitely isn't natural. Could he be a Cursed Spirit of some kind? Maybe a former Gojo clan member that died and became a Cursed Spirit? He might have intervened due to plain curiosity, after all if he is a Cursed Spirit then he should be more than capable of living for a long time.

It would explain his mastery over Limitless as well, he's had countless years to master it after all.

With the amount of power he is releasing he isn't someone to underestimate, pure power wise he was stronger than even Sukuna. Someone as powerful as this guy should be well known, the mysteries surrounding him keep increasing.

The energy he is releasing is quite odd as well, it isn't quite Cursed Energy but feels slightly similar to Cursed Energy .

His speed isn't to be underestimated either, he couldn't even see him when he appeared in front of Mahoraga, it seems he can't be called the fastest Jujutsu Sorcerer anymore.

"Are either of you going to say anything? Because the way you are both staring at me so intensely is starting to make me feel self conscious." The enormous grin on his face shows he is highly amused.

Ah, he can tell he's going to like this one, unless he tries to kill him and everyone he holds dear. You never know with these powerful figures.

"But first things first." He nearly misses it only seeing it due to his enhanced thought speed, but he grabs Sukuna by the forehead as he moves past but instead of dragging him along... just yanks Sukuna out of Megumi?

He did wonder how Sukuna's true form would look, having an extra pair of arms and an extra mouth is extremely useful for a Jujutsu Sorcerer.

"So that's what you look like, Sukuna the King of Curses. Not gonna lie, I thought you would be taller. Raiden make sure the child's body is fully healed, I should have completely healed him though. He appears to be processing a lot of information which I have had it split into smaller chunks and then sped up so he will likely wake up shortly instead of never. Also take him to his friends watching us through the crows, and just hang out with them until I'm done here." Wait another one?! Where the hell did she come from? And is she a maid? And did he say he healed Megumi? If he did then he owes him one, especially since Megumi's injuries are likely to be life threatening seeing as he had to handle the load for Unlimited Void.

"Yes Master!" she disappeared faster than even I could see but there was a flicker of electricity, a lightning user perhaps? And she is already with Mei Mei and the others, these two monsters just came out of nowhere and is that a fox on his shoulder? Why is there a fox on his shoulder?! Is this how other people feel when he constantly does crazy shit?

Wait…. That fox has nine tails. Could it be?! How was Tamamo-No-Mae reborn so soon? It seems to have a different form this time around as well.

He noticed Felix had turned to look back at a still shocked Sukuna with a cheshire grin, who he had dropped in front of him. 

"Now do you want to dance?"

Sukuna quickly got off the ground. 

"Well well, being looked down on like this is a first, and I have to say, it pisses me off!"

"Ha! Does it? What are you gonna do about it? Attack like a King or bitch out and pull your finger stunt again? That would be good too if you were responsible for doing that to yourself, I would thoroughly enjoy seeing how it's done. I even healed you up completely, it would be disappointing if I didn't get to witness how strong the so-called King of Curses truly is." 

He had a feeling he was being sarcastic at the end there.

Ah, he better get out of the way, he can use this time to heal up completely, and maybe team up with this newcomer to take on Sukuna, this wasn't a fair fight anymore anyways.

"You'll regret that!"

He teleported to the side with Blue just as Sukuna attacked the newcomer.

The newcomer easily avoided Sukuna's punch, and even had the audacity to appear in front of Sukuna and flick him into a building.

He turned to look at him, he made sure to be careful in case this guy decided to attack him but his worries proved to be for nothing. 

"Ah, by the way, my name's Felix, it would be impolite to not introduce myself after all this." He finally got a name for the face. He hasn't heard of a Jujutsu Sorcerer, or Cursed Spirit named Felix, hell he hasn't heard of anyone that looks similar to this guy, and is this strong.

"I'm Gojo Satoru, the strongest Jujutsu Sorcerer in the world." He gave a wave as he introduced himself.

Felix looked amused, "I see, I'll call you Satoru then. But the strongest Sorcerer eh? I guess you can keep that title seeing as I'm not a Jujutsu Sorcerer."

So a Cursed Spirit then? Well at least this one seems much easier to get along with than the rest of his kin.

"I'm not a Cursed Spirit either." What?! What does he mean, not a Jujutsu Sorcerer or a Cursed Spirit? He is far too powerful for a need to lie, which means he believes himself to be something else entirely, maybe it has to do with how his energy is similar but ultimately not Cursed Energy? Maybe he is a transcended Cursed Spirit? Something similar to what Tengen would become if he continued to evolve further?

Oh? It seems Sukuna's Domain just Expanded, wait why did it halt just after capturing Felix? Sukuna would definitely try to catch everyone possible in it as well, and this is definitely not his max range?

"Yeah, your fight is with me, don't try to involve others." He appears to be holding it back from fully forming somehow. He even seems to be able to use Reverse Cursed Energy as well, as he appears to be healing from all the wounds he should be sustaining so fast that he wasn't even able to see any wounds form on him. What an absurd level of healing. All while still having a grin on his face. Wait, the fox is still on his shoulder and is also healing? While not as quickly but still quick enough to not care. It also appears to have this alternative energy. In fact all three of them have it. He doesn't even know what's going on anymore.

"Since there is such a large open area I might as well have some more fun! Crimson-black blaze, king of myriad worlds, though I promulgate the laws of nature," he strikes a pose as he starts chanting. "I am the alias of destruction incarnate, in accordance with the principles of all creation. Let the hammer of eternity descend unto me!" 

"Why does this chant sound so familiar?"

"Explosion!" BOOOOM

Wait now he recognizes it! Did he just use a technique from fiction? He remembers watching an amusing anime that caught his interest that had something like that.

He came to the realization that this is all just a joke to him. He had a feeling that even if he and Sukuna were at full power and worked together he doubted they could take him.

He sensed an incoming attack heading for Felix from that assistant of Sukuna's. But it seemed to just be bait as that assistant of Sukuna's headed towards the explosion, likely to make sure Sukuna was okay. He wondered how Sukuna was able to inspire such loyalty. Felix waved his hand dismissively at where the assistant was. "Ah Ah Ah, interrupting my fun like that is no good." All of a sudden Sukuna's assistant falls flat to the ground. "Have fun with all that increased gravity." He was even capable of manipulating gravity?! What other abilities could he have? 

Sukuna was able to recover quickly from the explosion. "Enough games! Dismantle!"

Felix looked surprised for a moment before a look of understanding appeared on his face. "Oh? How interesting, your attack seems to be capable of breaching my 'Infinity'. This must have been your trump card against Satoru!" What?! He found a way to break through Infinity without Mahoraga?!

All of a sudden Felix stops and turns towards the observation room with a raised brow. 

"Ah, that girl, always taking things too far."

Did something happen in the observation room?

Felix must have noticed his concern, "Don't worry, no one is fatally injured, my maid just sometimes gets upset on my behalf and takes things a bit too far."

"You guys are free to refer to me as Felix, no need for the honorifics."

He gave a brief nod as Felix turned back towards Sukuna.

"Well now let's get back to you. You must have learnt this from Mahoraga right? It must keep on adapting after finding the initial solution, and it came upon a way of breaching Infinity which you can replicate. Your attack works by targeting everything, space, the world, quite an interesting way to get past Infinity I must admit. Unfortunately your attack wasn't able to get past my Multi-Dimensional Barrier, so tough luck. Still that's quite impressive, when I came to this world I didn't expect for anyone to be capable of breaching my Infinity, so that deserves praise."

What does he mean this world?! Going by his words he believes he is from a different world, and he has no reason to be lying…. So is it true? Are there other worlds out there? 

Words from his long gone best friend were brought to the forefront of his mind. 'Are you the strongest because you are Gojo Satoru? Or are you Gojo Satoru because you are the strongest?' 

If there are other worlds out there, then maybe he will have to find out, hell Felix, his subordinate and possibly even his pet fox are stronger than him? He's practically toying with Sukuna.

"Cursed Techniques can be quite simple, but they are capable of some interesting things when used to the extreme." 

"Now how about I give this a try." Felix waves his hand in a cutting motion. Could it be?! "Cleave. Oh, there goes your arm!" 

- Yuji Itadori - 

"Is Fushiguro alright?!" That pretty purple haired lady that was with the other new guy who also looks similar to Sensei, arrived from the battlefield holding him.

"This young man is fine, My Master was gracious enough to heal him when he grabbed the one known as Sukuna out of his body."

Woah! She has nice long legs and a great ass! He saw everyone tense up, Yuta ended up taking the lead.

"Who are you?!" 

"I am just a maid to my Master, my Master ordered me to come here and stay with you, so that is what I will do. There is no need to worry, I am not here to harm you, it wouldn't matter anyway, after all… you're weak." Didn't Sensei say something similar to the Mount Fuji Cursed Spirit? Hopefully it doesn't trigger everyone here like it did to the other guy.

"Great, another Satoru." He heard Shoko-san mumble.

"Satoru is the white haired one we interrupted the fight of yes?"

"That's right." Yuta-san adds

"Hmm well compared to this maid, he and Sukuna are also weak. So there is nothing for you to be ashamed about."

"If Sukuna is so weak to you, his maid, why is he taking so long to deal with him? Are you perhaps stronger than your master?" asks Kashimo-san

"Guh?!" All of a sudden he and everyone else here barring Kashimo-san who falls face first to the floor, fall to our knees as it feels like the world is falling down on us!

"I will give you this warning just once. Do not insult my master again. You will not enjoy the consequences. As if a maid like me is comparable to my master, I am but an ant compared to my master's magnificent power. He is likely just having too much fun and prolonging the fight." Great, he really is another Sensei.

She helped Fushiguro, so that's a plus in his book. Once she released the pressure on them he quickly got up and asked, "Ah, Maid-san, do you know when Fushiguro will wake up?"

Everyone else also got up, though Kashimo-san, and a few others had sweat running down their faces.

She looked towards him, "Hmm, my Master did not tell me when exactly, but I would say within the day."

"I see, thank you Maid-san!"

"The name my Master gave me is Raiden."

Her Master gave her a name? Did he know her since she was a baby or something and named her? Man he must be old if he knew her when she was a baby. He doesn't look old though.

He looked towards the screen showcasing the fight, did he just flick Sukuna into a building?

Awesome! Everyone in the room looks surprised except Raiden-san. After all Sukuna is the boogeyman, he seemed like a completely unstoppable force for anyone except Sensei, to see him being toyed with like that…. 

And is that a fox with nine tails on his shoulder? A Shikigami of some sort maybe?

"Was Tamamo reborn already?" Mei Mei asks

"Hmm, it's possible, but it seems to be far too short of a time period for a Special Grade Cursed Spirit to be reborn in, at least that would explain its change in form." said Shoko-san

So the fox is a Special Grade Cursed Spirit then?

"Who is this Tamamo you all speak of? The only people present over there are my Master, Kurumi, Sukuna and Satoru." Ah the Fox is named Kurumi?

"Kurumi? We haven't heard of any Cursed Spirits named Kurumi, the only similar Nine Tailed Fox Cursed Spirit is Tamamo-No-Mae, but it was exorcized a few years ago."

"What is a Cursed Spirit?" 

"While I do not understand how you could be unaware, a Cursed Spirit is the formation of an entity from the leaked negative emotions of humanity, generally of something they fear, like the myth of the monstrous Nine Tailed Fox of our past, or fear of Volcanoes." Choso-san explained, looking exasperated at her ignorance.

"Interesting, so the fear of the masses can cause the birth of that very fear, how intriguing. I'm sure my Master will be interested."

"Ah, by the way, my name's Felix, it would be impolite to not introduce myself after all this."

Felix, so that's his name. It's definitely a foreigner's name despite him looking similar to Sensei. 

"Felix, that sounds Italian." Ah Yuta Senpai is really knowledgeable.

"Hah, to see The Fallen toyed with like that is quite amusing." At least Angel's goal of killing Sukuna appears to be getting closer if Felix-san ends up dealing with him.

"I'm Gojo Satoru, the strongest Jujutsu Sorcerer in the world." Ah, it's just like Sensei to introduce himself like that.

 "I see, I'll call you Satoru then. But the strongest Sorcerer eh? I guess you can keep that title seeing as I'm not a Jujutsu Sorcerer." Is he a Cursed Spirit then?

"I'm not a Cursed Spirit either." Huh? Are there other races out there then? Maybe he just hasn't learned about them yet? He hasn't had much time to focus on his schooling with everything that has been going on after all.

"Impossible!" Going by Gakugani-san's reaction, maybe not?

"There are no other races." Even Kusakabe-san is agreeing, then why did he say he isn't a Cursed Spirit, or a Jujutsu Sorcerer?

"Oh? Are you calling my Master a liar?" He could feel there was a dangerous hint to her words.

He really didn't want to push his luck after she already warned them once, and it seems like everyone else was thinking something similar.

"Ah no Miss Raiden, I think the principal is just pointing out that we haven't heard of there being any other races, he meant no disrespect." Thankfully Yuta-san was able to calm her down.

"Hmph, I see." It seems she isn't going to go into detail about what her Master is then.

Everyone continued to watch the fight through the screen, eventually Sukuna got fed up and used his Domain Expansion. He didn't know why this Felix guy would heal Sukuna up, but as long as Sukuna was dealt with, he didn't care.

"Yeah, your fight is with me, don't try to involve others." 

"Huh? How is he able to hold back the Domain Expansion?! It looks like it's trying to form, but isn't able to reach its max range. This battle is constantly opening my eyes on how much we don't know about Domain Expansion." Stated Noritoshi-san

"Salmon?" 

"No, I don't have any idea how he is doing that." Not even Maki-san knows huh? The other more experienced Sorcerers don't seem to have a clue either.

"Hmm, it could be a new Anti-Domain Technique, he has already shown himself to be incredibly strong, he might have some hidden abilities he has developed." His apparent elder brother comments.

"You could be right Choso-san. But while these two are fighting, I think we should continue with our plan to deal with Kenjaku. Sukuna should be occupied long enough so it is possible." Hmm, Yuta-san is right.

"Hmm, you're right, it's best if we get Kenjaku out of the picture as soon as possible, no one wants to see what sort of monstrosity will be born from Tengen-sama's merger with all of Japan."

Seeing everyone's agreement Yuta-san looks towards Takaba-san, "You remember the plan?"

"Yup! I'll weaken him up for you, and then you deal the finishing blow." Yuta-san nods and they quickly leave. Thankfully Raiden-san didn't say anything, it seems she was honest when she said that she would just wait here for her Master to finish.

"Since there is such a large open area I might as well have some more fun! Crimson-black blaze, king of myriad worlds, though I promulgate the laws of nature, I am the alias of destruction incarnate, in accordance with the principles of all creation. Let the hammer of eternity descend unto me!" Isn't that an explosion spell from Konosuba? Can you recreate that in real life?

BOOOOM

Holy crap!

"Is he insane?! Causing that much unnecessary mass destruction!"

"Eh, don't worry about it, the fight between Gojo and Sukuna was bound to be messy, with this third party intervening. Let's just be grateful that it isn't aimed at us since he seems to be aware of where we are." Maki-san is right, plus saying anything more would likely piss Raiden-san off, and he did not want her to get angry, he had a feeling if she did it would not bode well for them.

"It seems one of you is aware of your place."

He could tell some people were pissed off by her comment but didn't act out, her show of power was still fresh in their minds after all. 

Oh, even that Ice User was dealt with easily, man this guy is overpowered, being able to manipulate gravity is scary.

"He's able to control gravity on top of his other abilities?!"

"Haha, I think it's best if we don't antagonize this guy, we don't stand a chance against him." Ah Momo-san is the same as ever.

"Heh, speak for yourself girly, I'm interested in fighting Miss Maid over here, I could tell you used Lightning when you appeared here, I wonder who's the better Lightning wielder between the two of us?" Ah, Kashimo-san was known for manipulating Lightning wasn't he?

Raiden-san looked towards him with a raised brow, "Hmm? I refuse, I only fight when my Master tells me to, or when he is disrespected, besides a fight against you would be boring."

"Hah?!"

"Enough games! Dismantle!" They all focused back on the fight, Sukuna's Dismantle wasn't able to do any harm though.

"Oh? How interesting, your attack seems to be capable of breaching my Infinity. This must have been your trump card against Satoru!" What?! Hold on, this guy has his own Infinity?

Everyone in the room was surprised by what he said, "A way to get past Infinity?!" Even the principal was surprised.

"Something like that has never been heard of without a Cursed Tool or Domain!" said Mei Mei-san

"It's a good thing that this guy intervened then-"

"This guy?! How dare you." Holy shit she just zapped Shoko-san! He wanted to punch her but the pressure returned leaving them all immobile.

"She still yet lives as I was not given permission to kill any of you, whether she survives will be left up to my Master, you are to refer to my master as Felix-sama from now on, or you will find yourselves in a similar predicament to that disrespectful woman."

"I-i'm s-sorry." Shoko-san is okay?! Ah she must have used 'Reverse Cursed Technique'!

"Ah, that girl, always taking things too far." He noticed?! How good are his detection abilities?

 "Don't worry, no one is fatally injured, my maid just sometimes gets upset on my behalf and takes things a bit too far." Doing that to Shoko-san is just taking things a bit too far?!

"Since my Master does not want me to punish you further I will release you." He sighed in relief as the pressure was released.

"You guys are free to refer to me as Felix, no need for the honorifics."

No thank you, he will refer to him as Felix-sama seeing as he values his health. No one wanted to antagonize her further, seeing as she was capable of easily immobilizing them all with what seemed like no effort.

Seeing as Shoko-san didn't want to pursue the matter, no one else brought it back up.

Still to think it's possible for Sukuna to have learned how to breach 'Infinity' from Mahoraga. Fushiguro had a really strong Shikigami then huh?

They continued to listen to his explanation, but were caught completely off guard at the end.

"A different world?!"

"Correct, it seems my Master has decided to reveal this fact so I will explain, my Master desired a vacation of sorts so he came to this world to relax and have fun. If any of you get in the way of that, I will be very cross with you. Just keep that in mind!" Gah! Raiden-san is being really intense! Hopefully no one does anything stupid to interrupt this guy's vacation!

"I see, thank you for the explanation Raiden-san." said Choso

"Being from a different world would explain all these unique abilities he has demonstrated, I haven't heard of any Cursed Technique that has as much variety as the abilities he is showcasing, the closest would be Limitless. It would also explain his claim of being a different race. Though that he has Limitless and white hair raises odd questions." said Noritoshi-san

"Now how about I give this a try. Cleave. Oh, there goes your arm!" What?!

- Felix -

This Cleave technique of Sukuna's is quite fun to use. I can already picture it. There is someone weak attacking me, and then in an instant they are missing their arms or legs with the bare minimum energy required to accomplish it. I could do something similar with Ouroboros by separating the space a limb occupies. What a convenient technique, I think I'll keep it.

It only works on those with Cursed Energy, thankfully I had Odin convert a miniscule portion of my Magicules into Cursed Energy as the fight began. I wasn't lying after all, I was curious about how strong the King of Curses was at his peak. Him not being able to target me with his Domain or other abilities would make this fight even more boring.

I was able to have Odin easily recreate Sukuna's Cleave with a combination of Battlewill, and Arts. Now it isn't technically the same ability, just a recreation. I only called it Cleave to mess with Sukuna, but maybe I'll gain a skill for it back in the Cardinal World, that would be fun. After all, skills can be rewarded if you have the prerequisite knowledge for something.

Cleave is essentially just a slashing attack that adjusts itself depending on how tough the intended target is, the tougher the target, the more Cursed Energy that is used in order to make sure the target is cut down in one attack. In my case I have Odin determine how much Magicules I need to power it depending on my desired result.

His other ability, Dismantle basically targets everything else, like inanimate objects, but as seen earlier, it does have some high level usage seeing as it is capable of cutting space, and the world itself.

Dismantle should also work on Sorcerers and Cursed Spirits, Sukuna just has to manually target them. 

Now I'm getting bored of this, now how should I deal with Sukuna? Ah, maybe I can take him back to the Cardinal World, I am curious how he would evolve after all. Sukuna isn't quite a human anymore, but neither is he a Cursed Spirit, when he was possessing Megumi he was similar to a Daemon as he was possessing Megumi's body.

When I separated Sukuna from Megumi I forced him to revert to his original form, and since this world follows different rules from the Cardinal World, he was able to stay incarnated.

If I do take him to the Cardinal World I do have to worry about his loyalty though.

'Do you have any solution to that Odin?'

'If the Master consumes the individual known as Sukuna with Beelzebuth, Odin can modify his entire being as deemed necessary, it would be possible to make him absolutely loyal and obedient towards the Master.'

Huh, do I really want to do that? Am I willing to cause the personality death of someone. Eh, he is my opponent so there isn't really a need to show him mercy. Pretty sure he has done some fucked up shit for shits and giggles too.

Plus, I just can't find it in me to care all that much about the current Sukuna beyond his combat capabilities.

'Alright, go for it.' Maybe he can be a butler? My very own Diablo.

I look towards a shocked Sukuna, it seems he was surprised by me copying his Cleave. Thanks to Thought Acceleration my conversation with Odin was basically instantaneous so the shock hasn't worn off yet.

"Alright, time to finish this up." I appear behind him, "Beelzebub!"

Yes! Let the chunni flourish! I turn towards Satoru with a grin on my face.

"Okay now that that's done let me introduce myself, my name's Felix White, Demon Lord extraordinaire from another world, and formerly from the Gojo Clan, Hello Cousin!" 

"Huh?!"

Author's Note:

Sup guys, finally we get to see Felix in another world, I tried to explain how the different power systems work in a way I was able to understand, so I hope that wasn't confusing.

Along with that, in Jujutsu Kaisen, it wasn't ever said if there was a barrier surrounding Japan, but it was implied so I just included it in. And then we have Felix just fucking around, he came here for a mini vacation after all.

The Yuji POV was kinda iffy for me, I didn't want to just increase the word count with repeating earlier lines, but I felt their POV would add a bit more context to what everyone is thinking. [BN: I added some extra Raiden shenanigans because otherwise it would have just been repetitive]

Anyways, thanks for reading, see ya.
