(Welcome to my Undertale after game fanfiction. I do not consider my story in anyway canon, though I will be happy if others like it. This is my own take on my own Frisk and their timeline. If you have an issue with the way I choose to see my Frisk, or the other characters within their timeline you do not have to read nor comment on my story. However constructive criticism is always enjoyed, and responded to via private message. Please enjoy)
Just one more time.
Just one more true reset.
This time she would get it, the answers she had tried to find so many times before. How to save everyone. She knew she was missing something, someone, that could give her the answer. She had finally gotten a clue this past reset.
"Beware the man who speaks in hands."
The river person probably thought the man who spoke in hands would hurt her, like so many had already tried in her past resets. A small sad smile crossed her lips as she walked up the mountain path to the entrance to the Underground. That was always the worst part of resetting, whether a small reset to end up fighting Asriel or the larger, true reset that she was currently walking to. Everyone forgot her, looked at her as a danger, a threat. They weren't too wrong, though she would never harm them. She could feel the other human soul, the one that was filled with Determination like she was. That one was dangerous, and it would take little for her to open up to that thing. Not that she would. She didn't trust it, him, any more than she would any human that gave the same darker feelings he did.
Pausing at the entrance she looked out to the vast expanse, smiling a little as she spied the town she and the monsters had made alongside humans in the valley. She always waited a year or so before doing the true reset, wanting the struggles to pass so she could see the happiness of her friends. These memories only she had, memories that helped her smile through every attack thrown at her as she spared everyone. The memories also made her cry more than once as she had to hurt ones she knew didn't want to fight her. Asgore, that fluffy dumby that had adopted her as much as his wife had, always had to be defeated for her to gain access to the next attempt to free everyone.
Another sigh left her as she realized she was going to have to watch Flowey kill him again, her body turning to the large cave behind her. The vision standing in front of the entrance caused a gasp to leave her, her eyes wide. Sans, hands in his pockets, stood before the entrance to the Underground, staring up at the sky. She knew there was no way he had known where she was going, no one did. She never told anyone when she left for this reset, the thought of hurting them before making them forget her entirely something she couldn't stand. And yet here he was, looking for all the world like he was expecting her.
