I made this Au myself. Basically, before a genocide route Sans finds the Gaster door and Gaster tells him about The resets and Genocide, Sans warns everyone, Papyrus believes him and so does Flowey, they make a plan to evacuate everyone. Toriel Sees the human kill the dummy and later a froggit, she tells sans through the door, and with that everyone believes them, toriel and sans volunteer to sacrifice themselves to give time to evacuate everyone, while Flowey slows the human down by blocking paths and attacking the human, Toriel knowing the human is dangerous tries her hardest dodging and attacking but falls, sans teams up with Gaster, Blocking the human at the bridge to Snowdin Town giving the Others time to evacuate every monsters into Alphy's lab, Papyrus, Undyne,and Asgore Take charge. For the rest of time The human searches for the hiding place, while papyrus and Asgore mourn sans and Toriels death. No Death is possible.no hit is not due to a glitch in the second phase. Arrow keys to move, hold X for slow soul.
