The story begins with Sans returning to his friends after being gone for hours. He explains that he was trying to escape a dog that attempted to bury him alive. However, the conversation quickly shifts to a more serious topic when XGASTER, a mysterious figure from another universe, appears. XGASTER reveals that the multiverse has been destroyed, except for the current universe, and that he intends to take Frisk, the player, with him to achieve perfection.
Frisk refuses, and XGASTER's true intentions are revealed: he wants to eliminate all imperfections and create a perfect world. XGASTER is accompanied by alternate versions of the game's characters, who seem to be under his control.
The scene shifts to a bakery, where MTT, a TV show host, is filming an episode. However, things take a turn when XMTT and XMUFFET, the alternate versions of MTT and MUFFET, appear and cause chaos.
The story then jumps to the city, where an earthquake has caused destruction. Alphys, Undyne, and Asgore try to escape, but XMTT and XMUFFET appear, threatening to destroy the city. Frisk and their friends, including Papyrus and Undyne, decide to intervene and save the city.
Throughout the story, XGASTER is shown to be manipulating events from behind the scenes, and his true intentions remain unclear. The story ends with a poem from XGASTER, expressing his desire to be free and not broken, and his willingness to do whatever it takes to achieve his goals.
