Keitaro was seen relaxing on a silent field. His eyes scanned the green scenery infront of him, if he was being brutally honest this place looked like something out of a fairy tale.
It looked incredibly pretty, he should have known, that people with pockets as the Worthington family had a place like this inside their territory.
From what he could recall, they had given him access to this very secluded area for his training, he could use this area in order to grow his power more and more.
However, Keitaro wasn't that trusting of the Worthington, sure they may seem generous but this whole thing looked too good to be true.
He could not think of a single reason why they would give him access to so much in exchange for training their son.
He could not really think of anything that could help his current situation, thinking about it, it seemed like they wanted to gain something out of it.
He did not trust them one bit and thus with a flick of his wrist, a barrier appeared into existence. It wasn't just any barrier, this one, in particular, was born into existence for one single purpose.
It was built in order for anyone outside the barrier not to see what was happening inside the barrier.
He did not feel like being spied on as he trained and thus this was the first vow he placed on his barrier.
He made sure to carefully craft the barrier shell making sure to make it as complex as possible, he did make sure to place a binding vow on it.
Making it so that in exchange no one outside the barrier could even see if the barrier was there or even see through the barrier.
Anyone who found the barrier would not be stopped by the barrier and would be able to pass through it.
After finishing the first barrier he decided to make a second one, just a bit smaller than the first one, the vow went as follows.
"Should anyone breach the outer barrier, a teleportation trap lay in wait, Teleporting the trespasser far away."
Welp for safety reasons, placed another barrier, which utilized Akane's illusions, basically making it so that even if someone were to somehow bypass those 2 defenses, they would be trapped inside an illusion that would have them walking around in circles or just making them walk outside his barriers.
Maybe he had overdone it just by a tiny bit, just maybe he had overdone it with the barriers but he didnt care, he wanted his training to stay private.
He was in no mood to let people figure out his moves as of yet.
He sighed a bit as he felt all the vails taking into effect. He knew that to the untrained eyes, nothing had occurred, it would just look like an ordinary field.
This is what Keitaro wanted, he was satisfy with his choice, and now the only thing left for him to do was probably like the one thing he had been putting off for so long.
He needed to unlock his domain expansion...
Keitaro closed his eyes and focus firmly on his inner world, he took in a deep breath as he felt the energy come straight to him.
He was currently in the middle of his inner world, he could see it.
His domain sitting there, just waiting for him to give it a call, just waiting for him to finally call its name.
"Mirage Labyrinth."
As those words left his mouth, he felt a surge of curse energy erupt from his core, it was pulsing outward like a tidal wave.
The ground beneath him started shaking, and the air crackled a bit, to finish it off, Keitaro pressed his palm onto the earth.
For some weird reason, he felt as if he needed to do this.
As he did this, a distortion was seen rippling outwards, it was swallowing the whole field.
Keitaro's domain started taking shape and with Keitaro's advanced knowledge of barrier technique, it was a piece of cake for him to fully form a barrier domain.
However, if he had one problem with it, it would be the very simple fact that he could feel his domain was sapping too much curse energy from him.
This probably had a lot to do with the fact that the domain was unrefined, which is something that he would fix right there.
As he made sure to fix any problem with the domain, he couldn't help but look around at the beautiful sight that his domain could conjure.
A swirling vortex of curse energy now took the place of the sky, there were no stars in this sky.
Instead, the stars were replaced with curse seals, he could see the curse seals everywhere inside the domain.
This meant he could teleport anywhere inside the domain, kind of like his unseen storm but instead with a sure-hit attack.
He felt as if the laws of physics held no sway inside his domain. Time seems to flow inconsistently, in certain areas, time seems to move at a super speed while in other areas time seems to move at a snail speed.
Something else I figured out was he could control what gets sped up and what gets slowed down...ahahahhaha.
Just thinking about it made him chuckle, and considering his domain sure hit wasn't a deadly one, in a clash of domain with Satoru Gojo.....he had the edge.
Meanwhile in Japan.
Gojo was seen seemingly cooking dinner for the two children in the house before he suddenly felt as if someone had insulted him, he felt as if he just lost his edge.
Nah, that couldn't be it at all, he was fine.
Back to Keitaro
And to make it all more beautiful, he could switch what could be active, using his Ct, what seemed to be a perfect copy of himself could be seen, they were perfect replicas of himself, unlike the weaker one he could make before.
Those replicas could genuinely be considered perfect, something he noticed from those replicas was the fact that he could switch between them and could probably also switch his opponents too.
This day was just getting better and better as he looked around his domain, sure the sure hit of this domain wasn't as deadly as an unlimited void, but this domain suited him much better.
The strategic use of this domain was endless...
