#I wanted to call this either undersoul or soultale but I assumed they were taken and I was right

Alright, I’ll be honest. I’ve been searching ao3 for an Undertale fic where the main character is a human and falls to the underground, yadda yadda, but once they make it out of the ruins (because really, who dies in the ruins??), they die. However, instead of resetting (if they even can, as their soul may not be very DETERMINED), they just decide willingly(? I mean they were murdered, but they agreed post-mortem, probably because dying hurts like a buttcheek on a stick) to be used to help break the barrier. However, to make it more interesting, they absorb themself(?? I cannot think of a better way to word this) into the monster who killed them, or a monster they just like good enough, and refuse to be absorbed by Asgore.

And actually yeah I’m staking my claim on this idea, I’m just putting it out there because I wish it to be so

My brain kinda took it in the direction of ‘the human is terrified, but also a Sneaky Snitch and makes their way through the entirety of the ruins without running into a single monster (excluding maybe Flowey, but they’d definitely run away from him), and run through all the way to the pre-Snowdin area (does that area have a name? It’s not Snowdin, but it’s snowy). However, we are going on the assumption here that in the game or original timeline or whatever, Toriel asked Sans to make the promise to her after Frisk met her and stayed a while. This is important because after the stick on the ground breaks, the mc snaps around, and then they fucking die. Since they rushed through the ruins and dodged meeting Mom.

So now that they’re dead, soul light blue, displaying their Patience (which was already shown, since it took for-fucking-ever to solve the puzzles in the ruins without help, while also avoid encountering any monsters safely). They freak out for a while, and when they regain composure, Sans is looking at them weird, talking to them about how ‘I knew that human souls stuck around after death, but I didn’t realize they kept their consciousness,’ and explaining what would happen to them to calm them down, making at least three puns during his whole spiel.

So the human, deciding ‘fuck it, I’m already dead and this guy’s fuckin hilarious,’ absorbed themself (still cannot think of any way to word this better) into Sans, granting him a fuckton more power and dodge time, because patience doesn’t mean you can take hits. Sans, very confused and vaguely distressed, does not know what to do, and just takes a shortcut to Undyne.

And then it continues escalating from there, probably
