"Yep! The one made by the detention center's special curse was what you would call an incomplete Domain. Sort of like a messy first pass instead of the fully realized thing. Whereas this," he motions with his free hand, "is the real deal. There's a barrier trapping the both of us inside of it, and any attacks that the owner makes imbued with the Domain around us are guaranteed to hit."

"...shit," Tōkan says mildly.

Most sorcerers would have burnt to ash... just from existing inside his domain. Having this difference in power thrust in his face like that... On his pride as a curse, this is completely unacceptable.

He sends a huge stalactite of stone right at the sorcerers.

"Quite! But there are downsides, and a few ways to counter. The biggest downside is that Domain Expansion is expensive, and imbuing techniques with it so that they always hit is similarly expensive." He reaches out touches the stalactite just before it hits them both; it disintegrates. "And just because the technique hits doesn't mean it hurts. Did you see how it broke against my cursed energy instead of me?"

Nodnodnodnod.

What.

"Now, in theory, you can break out and leave the domain entirely. It's impressed on a barrier, after all, and once you're outside of the area of effect, you're free. I don't really recommend this, though. If someone is powerful and skilled enough to make a complete Domain, their barrier is likely to be quite strong, and most likely reinforced to the inside, to keep its victims inside."

...fuck this dude.

The curse starts sending a barrage of lava at him—here he can just overwhelm his Infinity and kill him—

"But the most effective way to counter another's Domain," he continues, reaching up to remove his blindfold, "is to expand your own." He holds up his right hand, and wraps his index and middle fingers around each other. "Domain Expansion:"

  "I

Jogo perceives everything. Every mote of dust floating within the barrier. Every breath every person in the Domain takes. The rhythm and sound of their heartbeats. The way space itself twists as the inferior Domain is extinguished. The air pressure around them, the composition of the ground beneath their feet, the precise way the barrier around them has been strengthened, the way light is brought in from the outside and then twisted for this exact light level, the exact configuration of the cursed energy around them—

—And more. Too much. He is an insignificant speck in a grand, uncaring cosmos. He is small, pathetic, and meaningless, in a universe that is bigger than a mind can really comprehend. He is a miniscule, random happenstance, who will exist for the briefest of brief moments, and then be extinguished, and nothing will care. He is a speck, stranded in the infinite, and against it he is nothing at all.

"What happens then is a contest between Domains. Usually the more refined one will dominate the space."

...everything is empty. Or full. At the same time. Their surroundings are crazy, like he's standing in the middle of vacuum or nowhere or everywhere.

The curse, though... is just standing there. Not doing anything. "What happened to him?"

"He is experiencing the inner world of Limitless - that is, the name for the Gojo clan technique - combined with the very special inner demons that make up the fabric of my being."

"He's not having a great time right now."

"It's innate? The technique."

"Mhm. Usually this is where I would kill him, but I have some questions to ask of him." He begins walking towards Jogo, gently tugging Tokan along. "So I'll just rip his head off."

Itadori follows along, happily enough.

When the curse is within an arm's length, Gojo reaches out his hand to grasp his volcanic head. Just before his fingers touch, Jogo's neck twists, and the head is torn away from the body.

Gojo grabs hold of the head, and dismisses the Domain. The hand keeping firm hold of Tokan is released, and Gojo uses it to pull his blindfold back on.

"So! Hi there. Feel like having a chat?"

That was a whole new level, what the fuck.

"C'mon. Don't want me to put you back, do you?" he teases, clearly... not really joking at all.

"Die screaming!"
