3 Dᴏᴍᴀɪɴ Exᴘᴀɴsɪᴏɴs ᴀᴛ ᴛʜᴇ Sᴀᴍᴇ Tɪᴍᴇ

I decided to visit Yuji for the day, my broken arm had already healed. Nothing too interesting was going on, I did however, notice that the teddy thingy doesn't punch Yuji anymore. He's able to control cursed energy very well, and very fast too.

We were watching Lord of the Rings when I felt a sudden presence at the doorway, judging by how well it's hidden, it must be Gojo. I wanted to say nothing but me being me, I held the can of soda in my hand, and by using my cursed energy, my movements were much faster, not the fastest I can do but it was part of my experiment.

Yuji looked at me shocked and looked to see why I spilt my soda behind me, and see Gojo. His fingers were crossed meaning the "infinity" was on. He was completely dry. 'His reaction speed is pretty fast, if a single drop touched him then I would be able to work out how fast he is.'

"Ehhhh! L/N-chann~ that was mean~!" Gojo whined like a baby, "And watching teenagers while hiding your presence is creepy." Yuji look between us confused.

Gojo clapped once with a big 'ol smile on his face and told us he was going to teach Yuji a lesson about domain expansions. Interested by how he was going to do that, I tagged along. He agreed and grabbed the back of our collars and POOF, he's standing on water in the middle of a forest.

I look around and make eye contact with a curse, most likely a first grade or higher, "Gojo-sensei, we were just a school a minute ago right? How did we get here?" 'Perfect, now I'll find out more about the Strongest Jujutsu Sorcerers powers.'

"Ohh, we warped here." Yuji sweat drops and looks away while I'm stuck in my thoughts, 'Warped eh? That crosses out  quite a few possibilities... just how many techniques does this man have?!?'

"That is... Sukuna's vessel!" The curse muttered extremely quietly, and we were a safe distance away, due to my superb hearing I could clearly hear every single word that came out of his mouth.

The curse had thoughts flying through his head,  judging by his tone and surprise, whoever he is needs Yuji, or more specifically Sukuna's revival.

"You went back and got a shield?" I already dislike this guy, the cockiness in his voice just makes me wanna slap him, trap him in a barrel and throw him in the middle of the Pacific ocean.

"A shield? No, no! I told you, they're here to watch!"

"Bringing people that'll only drag you down!"

"It's fine, after all.. you're weak." 'I forgot about the other idiotic over-confident egg here..'

"Don't underestimate me brat!" Molten lava and magama shot out of the top of his volcano-shaped head and out his ears.. take that out of context and see how weird that sounds.

"Ryoiki Tenkai! Coffin of the Iron Mountain!" The domain was laid out and I look around, this domain expansion is really powerful... normal humans would be cooked instantly. Too bad he's gonna end up dead. I mean, his enemy is Gojo. THE Gojo Satoru.

Gojo went on to explain domain expansions to Yuji, using video games as examples. "L/N-chan!"

I look over at him, "Do you have a domain expansion?" I stay silent, debating whether or not I should tell the truth of lie. 'Lying would turn out really bad if I use it in the future, I would lose all their trust that I would gain...' Eventually I decided to tell them the truth, but not tell or even hint at them that I can stop curses and cursed techniques from being use.

"Yea. Why?" Gojo smirked at my response,

"Use it."

My eyes sharpened, "Why?" I ask, trying my best to keep my voice stable,

"Well, I did say before that we don't know what your grade is. If your domain expansion overtakes the curse over there, it would make you a special grade that could possibly overtake me, you are a kid after all. And nope, you don't get a say in this."

'As long as I don't use my Electrical Lock they wouldn't know.'

"Fine. But you have to use your domain expansion after too." He nods, instantly agreeing. I turn to the curse, already knowing that my domain is more refined than his. The curse looks increasingly nervous.

My hands hover over my chest and I start to float, "Ryoiki Tenkai-"

A weapon slowly appears out of my chest, I take it and hold it up, letting blinding strikes of lighting hit the area around me, my glowing eyes stare right into the curse.

"Plane of Euthymia."

In one swift movement, I strike the weapon down and to the side. The very world cracks behind me, pieces of reality falls and reveals nothing but darkness. Everyone gets sucked in while I seemingly disappear. Gojo, Yuji and the curse look around, but then a cement arena with a tomoe carving appears under them, a mixture or surprise and fear is in Yuji and the curses face. Gojo just looks like Gojo on autopilot.

Broken Tori's and dead land comes out from underneath them, almost like surrounding the arena. A blood-coloured moon and murky-red skies are all that is seen in the distance.

"W-What?" Yuji mumbles,

"Yo."

"HUAAAAA!" I appear behind him, scaring the shit out of him, they all face me, realizing that I was sitting cross-legged on air calmly, the weapon no longer in my grasps.

"So, this is my domain, now show me yours."

"Okkay!" He says making an 'ok' sign with his hands. He slips his fingers under his blindfold, slowly pulling it down dramatically. I look at the curse real quick, noticing that nothing but fear is in his face.

"Ryoiki Tenkai, Infinite Void." He says crossing his fingers. We get seemingly time travel to everywhere and nowhere at the same time, seeing, hearing, tasting, smelling, feeling everything. Gojo grabbed me and threw me on his back while he held Yuji on the stomach which one arm.

"You're surprising good-looking without that blindfold, Blindfolds." He looks at me with a smirk, Yuji has a worse-timing-ever-to-say-that look on his face.

"Aww~ you falling for me Angel?"

"And that is called pedophilia kids." I reply rolling my eyes,

Yuji looks even more weirded out. Gojo turns his attention to the curse and says a dramatic speech about his over-powered domain. I didn't pay attention until he placed his hand on the curses head and effortlessly decapitated him.

'Rip. But you can't cuz Gojo was the one that killed you.. sooooo goodbye weird curse.'
