Above Shibuya crossing a man with long black hair dressed as a Buddhist priest stared across to another building seemingly at empty air, but to those who could see beyond the veil, it was clear what the man was looking at. It was an unusual sight to see, a skeleton with closed lids sleeping atop the neighboring roof.
The man's interest had been peeked when he noticed the high amount of cursed energy contained within the skeleton, signifyingthe skeleton to be of special grade. But what most intrigued the man was the Curse appeared to be made up of both Cursed Energy and Positive Energy, so after a short while of observation, he made his move and landed upon the same rooftop.
Sans woke up with a start, quickly teleporting behind the newcomer nearby. "Well what do we have here? You know it's not nice to watch someone while their sleeping."
The newcomer did not flinch at the sudden movement and merely turned his head slightly to look at the smiling skeleton, 'Teleportation eh, he may prove even more useful than I initially thought,' "My apologies, I simply wished to introduce myself to the newest special grade cursed spirit. Your quite special you know that, from what I can see you're the first natural cursed spirit to be capable of the Reversed Curse Technique without killing themselves. Not only that but you're appear to be composed of the stuff."
"Eh, thanks I guess, but I think you'll find I'm quite different from your typical Curse as a result. And depending on what your intentions were in approaching me, (sockets go dark) you're gonna have a bad time, I can see you LV," he says as his left eye socket ignites with cursed energy and a mixed cyan and purple heart emerges from the intruder's chest before turning dark blue as his body is highlighted in the same color.
From this the intruder felt a subtle pressure, as if a subtle weight were holding him in place. "That's quite the LV for a human, though considering how old you are I guess it shouldn't be that surprising. But the amount of Souls contained within you would be surprising no matter how old you are," he finishes as thousands of tiny upside down white hearts light up around the human's body before also turning dark blue.
'He can also feel my Cursed Spirits, and seems to be able to interfere with their summoning, I wonder if he can do the same with shikigami,' "You're awfully perceptive aren't you, but I think we're getting off on the wrong foot," he turns fully to face Sans and extends s hand "My name is Suguru Geto, a Curse User here in your best interest, and you are? My new weary friend."
"Sans, Sans the Skeleton, now let me make one thing clear to you Curse User, I don't trust you and I don't like you, so let's not cross paths again, Kenjaku" on that note Sans disappeared from that roof top.
'He knew I was old, and he knew my true name all just from looking at me, I wonder what else he can tell?' Kenjaku thought as he decided to just continue with his day, otherwise he would be late for his meeting with the Disaster Curses, as he left he begun to adjust his plan for this newcomer and consider whether or not he can use him as an ally or a mere tool against jujutsu Sorcerers.

Over at the edge of Tokyo Metropolitan area Sans appeared from his recent teleportation and quickly sat down propping himself up with his hands behind his back.
"That was scary, I haven't fought yet so that could have been real bad, though I have a feeling I could have held my own as long as that body snatcher didn't use his domain though that might be my inexperience talking. I also managed to learn some things, first is I'm definitely in the world of jjk, second the night parade incident already happened based off what that Check told me."
Sans began to fully calm down as he talked things out loud, "Third I can prevent or at least stall the summoning of spirits by holding their Soul still, I wonder how that would work with Sukuna and Itadori considering they share the same body, or even the shikigami of the ten shadows technique."
"For now I should probably practice some of my moves considering Kenjaku now knows of me, I'm sure he'll try to find me now that he knows of another special grade curse, whether to add me to his plan to revive Sukuna or to add me to his army of curses I don't know but I don't think it matters."
"For now I should return to that church, maybe use it as a sort of base until I'm confident enough not to need it, plus it's close enough to the city I should have plenty of stray curses to practice on. Though I may just be making excuses for myself to stay near my "birth place," I think I remember hearing curses like to stay in the place their born, something for future Sans to figure out I guess."
With his mind made up Sans stood and teleported straight back to the abandoned church he was born in.
