Basically, dusttale with ut:are, sans has the normal au, before he tries again, but he finally won, and they finally quit, don't they?

Time goes by, sans starts to go alone, given his name, "Takwa" was the possession, during unstable during this world, he looks guilt and alone at the same time, papyrus looks creepy and nightmarish during they're helping him, he starts as his own population as the phantom, just like him, he can feel the loop has corrupted, the save file has corrupted too, he gains so much pain to himself just to end it.

Undertale: Something Failure.

Sans was to get rid of this soul, so he decided to rip it off, but he did.
