September 7
Sans was walking through the city, of south west Tokyo, Kanagawa Prefecture, on his way to the sewers to meet up with Nanami, normally he was supposed to always be accompanied by someone of Tokyo Jujutsu High whenever or a grade 1 Sorcerer or higher whenever he leaves Tokyo Jujutsu High.
He was following these rules, even accompanied Gojo on his trip to Africa for a bit when Gojo was notified that Nanami had encountered a Special Grade Curse, so Sans took a shortcut back to Tokyo and was told that Nanami was clearing out sewers alongside a grade 2 Sorcerer.
While walking he passed an ally when he heard some soft meows coming from behind a dumpster. Distracted and not in much hurry he decided to check it out, there in a box was a small kitten, and it looked at him, which was weird considering he was a Curse and animals shouldn't be able to see him if he wasn't trying to kill them, so he decided to take it with him.
He scooped it up in his boney hands and it finally stopped crying, he turned to look out of the alley at the many people walking the city's streets, 'a floating cat is probably gonna draw too much attention,' So for now he stuffed the cat into his jacket pocket, with it's head sticking out, and disassociated his close from himself, allowing it to become visible to civilians. He made sure to cover as much of his face with his hood as possible and kept his hands in his pockets, keeping whatever part of his body that civilians couldn't see hidden in his clothes.
Sans then rebegun his journey to meet up with Nanami, as he did so he thought back to the anime in his previous life, it could be quite vague at times with the dates of certain events. Like the dates of the deaths from the bridge incidents, he remembers them being pretty clear cut even if he can't remember them now. But with the dates of events like what he believes he is currently living through, it can be quite vague with days or possibly weeks passing during certain events without clear explanations.
When he went with Gojo to Africa he assumed that it was Gojo going to tell Yuta about Itadori and that while he was there he could make a Pact with Yuta, but Gojo got a call from Nanami while they were traveling through Africa so Sans Shortcut straight back to Jujutsu High the next day.
So Sans never got to make a Pact with Yuta but Sans hoped to meet Yuji soon so he could take a look at Yuji's Soul, he was hoping that as the protagonist of the Manga/Anime that his Soul trait would be Determination. Not only that but he wanted to see how being Sukuna's vessel would affect his Soul.
When Sans finally arrived at the sewers he reassociated his clothes and moved to pull his hood down, the cat had latched itself to his arm, so he simply held it, used his other hand to pull down his hood, and stuck the cat into his hood where it finally let go. He noticed Nanami hanging up his phone while he was standing with another Sorcerer, they were also surrounded by transfigured humans.
Looking at them Sans could see, while their Souls were still there, their souls still trapped within their bodies, their Souls were damaged by the transfiguration, still allowing senses to be felt but disallowing any control, forcing them to be in constant pain before eventually shattering. Sans' sockets went dark looking at them "-I'll leave the rest to you," Nanami said, addressing the Sorcerer next to him.
Suddenly Gaster Blasters appeared in front of each transfigured human before putting them out of their misery, reducing them to dust. "No need," Sans said, stepping into the open. He had held out a token with the symbol of Tokyo Jujutsu High, given to him by the Higher Ups and imbued with a specific CE, in order squash any doubts of who he was.
"The one who did this obviously set it up as a distraction for something else, and you know where they are, so let's go, I have a personal lesson to teach them." He finished as he put the token back into his pocket.
Nanami stared at him for a moment, he had been startled by the sudden appearance of draconic skulls that eviscerated the transfigured humans. He looked at the "Friend" that Satoru had apparently sent, trying to figure something out by studying his skull only to give up upon not finding anything.
"Alright, they should be at Satozakura High, there's been talk that you can travel quickly, think you can get us there?" Nanami asked, directing his focus on dealing with the more pressing issue.
"Sure, it won't be instant because I've never been before but it just needs to be within my line of sight, so a few rooftop shortcuts should do the trick." Sans said as he was was just about 3ft away from them.
"Wait hold on, you know this Curse Nanami!?" Asked Takuya Ino, the Sorcerer who originally handled the ambush in the Manga.
"Yes and no, while I've never met it in person, there's been talk of a Special grade Curse that has joined humanity's side and now works for Jujutsu Headquarters at Tokyo Jujutsu high, that token is proof that this is it," Nanami explained.
"So those rumors were true, unbelievable," Ino said in disbelief.
"Yep, close enough, now each of you take a hand, my shortcuts are a lot easier with direct contact." Sans said as he held out a hand to each of them. Nanami took his hand right away while Ino hesitated before noticing Nanami's lack of hesitation and just taking the Curse's hand. The next thing they knew, they were on a rooftop directly above them.
"Now which way is the school?"

"Junpei! Run!! I don't know how you know this guy, But just run away! Please!" Itadori yelled as he was held up against the window of the school building.
"Don't worry Itadori! Mahito isn't a bad per-" Junpei thought back to what he had witnessed, "a bad, person."
Mahito swung his other arm around Junpei, "Junpei, you're a pretty smart guy. But you overthink things when you should act, which puts you in some pretty bad spots. This is a perfect example!" Mahito finished in a cheery tone, "All those people you think are stupid, well, guess what? You're just as stupid a-" Mahito is interrupted as the window shatters and his arm is suddenly severed 7/10nths of the way up.
"So you did survive, that won't be the case for much longer." Nanami said adjusting his glasses.

(Sorry this one is shorter but I couldn't find a really good stopping point if I had continued any further so here is an Omake as an apology)
Omake
Fushiguro was going through his phone late at night when a memory surfaced, he had a feeling of dejavu when he had first met Sans so he decided to Google the name. What came was an old game that had circulated the internet back in 2015, specifically a certain character from the game that looked eerily similar to a recent Curse they met.
He initially chalked it up to just influence from the game on humanity's consciousness that influnced what the curse looked like, but as he looked deeper the similarities keept adding up until he came to the conclusion.
"WE'RE IN A GODDAM FANFICTION!" He scremed as he threw his phone on the floor shattering it
"SHUT THE F*** UP, SOME OF US ARE TRYING TO SLEEP!" Maki yelled from the neighboring Dormitory, which due to how the dorms were set up, was just to the right of him.
