Summary
One more reset was all that was needed to fix their mistake and find another way to pass Undyne. What happened last time was a mistake fueled by pain and fear. This time, they knew what needed to be done. Except when Frisk awoke, they weren't alone, standing next to them was another child, and what's more, it was from a race they'd only see on occasion. What were they doing down here and why? Would they be able to handle what awaits them beyond these golden flowers?

Summary
This is a story about a group of broken people, simply existing together—breathing, interacting, without even forcing you to relax.
Most of the characters chosen for this story come from source materials that already involve severe trauma.However, there will be no further depictions of gore or violence in this story.
And there will absolutely never be any sexual innuendos.(Off-colour jokes, if any, will be strictly adult-to-adult—and never flirty.)That said, since I tend to let characters actively explore their own trauma, there may be mentions or descriptions of past events. (Which is why I’ll include trigger tags in the notes below.)
Don’t worry, there won’t be any cross-universe romantic ships.
Some Original characters appear in here, but the majority of characters in this story do not belong to me.If you feel a character seems a little out of character (OOC), feel free to bring it up, and I’ll consider making adjustments.
However, if it’s only a slight difference, it might simply be due to different interpretations—after all, “There are as many Hamlets as there are readers.” -

Summary
Wake up buried in snow, alone, and with no memories?
Check.
Kepp seeingg numbers, words, and text floating around every object and surface as far as the eye can see?
Also check.
Why does every person he meets say he needs help?!
His perfectly fine if you ask him."I wonder what determination taste like"
Note from the author:
This is my take on Fatal Error—a much more none canon, this isbt even OOC this is just straight up diffrent person with the same name, amnisiec version of him.
He’s also not fully canon-compliant in terms of power scaling and has and maybe different origin and personality.
It’s my reimagining of him.
Glitchy, lonely, and filled with questions, bad puns, power to blow up annoying people and some more puns. -

Summary
How many runs has it been?
Not even Chara could count them. Over and over again, they saw the Human kill those they had cherished when they were alive. They had wished to do something about it, and had even suggested to the Human to pick another route only to be in vain. However, when an intervention comes from the Man who Speaks in Hands, they are given an opportunity to give one being the memories of the previous routes.
Garden of LOVE(Level of ViolencE) is a three part series and take on the already popular concept of Dusttale. In the series, Sans's memories are given back to him by Chara who aims to stop the Human's genocide routes.
