Throughout Heaven and Terra (Arknights x Jujutsu Kaisen)

Chapter 2: Entrance

"So, you don't even know what originium is?" The Liberi man's eyes widened as he looked dead ahead at Gojo.

The both of them were now walking, with the Liberi being the guide and directing the both of them to any exits he knew, as he has more experience in this city than Gojo did.

"Eh? Should I?" Gojo merely turned back and looked at him with a smile, finger pointing to himself. Although he was acting like this, he had already made a few connections to the black shard in his pocket and the micro-particles in the other man's body.

The connection became clearer when his six eyes revealed the structure of the other people's body he blew away. Although they were covered head to toe, his six eyes could easily tell the rocks growing on the skin of their bodies, much more severe than the guy in front of him.

"It's common knowledge, literally everybody knows that; did you not use arts earlier?" His hands motioned back at the scene of Gojo blowing away the people in white masks with some sort of repulsive force.

"Mmh, arts and originium huh? And how do they correlate with each other?" Gojo cupped his right hand and placed it under his chin as he spoke the question. An idea came up in his mind with the high energy an originium had, and this "arts" this person mistook his Cursed Technique with.

"Well, you can't really use arts effectively if you don't have a high amount of originium in your body, and I don't see any on you..." the Liberi took a second to pause, "unless, well, it's all hidden away."

Gojo made a humming sound as he stared at the blackened sky. 'Those rocks have stopped raining ages ago it seems.' Speculations and theories were running through his brain, an amount only a supercomputer would be able to handle. He formulated his next response, "Well, I don't remember ever hearing about this originium thing, nor having any in my body," he gave a hearty shrug.

"Wow, really?" The Liberi man squinted his eyes, as if trying to peer through the one standing before him. His eyes would find nothing. "Everyone has at least some amount of originium in their body, as it's always in the air, you don't develop oripathy until it's in an extremely high concentration," he paused his train of thought for a brief moment before sighing. "I really don't know how you did that thing before."

Well, he did feel many microparticles building up on his Limitless barrier. From what he could, very vaguely sense was powering this city had the same signature as originium.

Could it be a staple universal energy source?

Mulling over what to say next, he made his choice, "Simple really, cursed energy," Gojo had decided to reveal his hand. 'It can't be that bad to reveal this,' he thought to himself.

"Excuse me?"

"Cursed energy, they're born from negative emotions." Gojo was now looking completely forward as he walked, making gestures as he spoke. "Though, not all people are born with a high capacity of it, or a high capacity to wield it, so some are less able to utilize it effectively." With a contemplative look, he looked directly at the other man. "Well, you have like; absolutely zero cursed energy."

'Just like everybody else I'm sensing in this world,' but Gojo decided to keep that a secret. Maybe there could be exceptions? He shouldn't be too surprised at whatever this world would throw at him.

"...I've never heard of that. So does that mean you have high amounts of, uh, negative emotions?" A hand was placed on the Liberi's head as he tried to make sense of it all.

"Negative emotions? Not really a lot of them, I was just born special, ya' know?" Gojo's head was turned back to him with a playful grin on his face, the recipient felt something was wrong with that.
