Plot
Human teenager Kris arrives late to school one morning. After being paired up with their delinquent monster classmate Susie for a group project, their teacher, Alphys, sends the two to get chalk from the supply closet. However, the closet pulls them into a strange realm—the Dark World—where they meet the dark prince Ralsei. He tells them that the three are heroes destined to close the geyser-like Dark Fountains that give form to the Dark Worlds, in order to preserve the balance between light and dark. A new Dark Fountain has created a new Dark World east of Ralsei's, guarded by a dark creature called King. Susie, uninterested in Ralsei's affairs, initially joins King's son Lancer in trying to stop Kris and Ralsei, but both are convinced to change sides and join the party.

Lancer refuses to confront his father and does not want his new friends to be hurt, so he imprisons them in King's dungeon. Susie helps Kris and Ralsei escape and fights Lancer, but ultimately reconciles with him and promises not to hurt King. Kris, Susie, and Ralsei confront and battle King, after which he falls over in exhaustion. Ralsei heals him out of pity, which King exploits by incapacitating and preparing to kill the group. Lancer then leads the Dark World's inhabitants in overthrowing and imprisoning Kin. After battling King, Kris closes the Dark Fountain, revealing that Dark Worlds are ordinary rooms transformed, and returns home. That night, Kris rises from their bed and rips out their soul, throws it into a bird cage, and draws a knife.

The next day, Kris and Susie return to the Dark World to confirm it was real. When they reunite with Ralsei, he urges the two to leave and work on their school project with their classmates Noelle and Berdly. Kris and Susie head to the library's computer lab, but discover a new Dark World has been created inside it, and Noelle and Berdly have both been sucked in. The Dark World's ruler, a robot named Queen, kidnaps Noelle, intending to use her to create new Dark Fountains. Berdly, out of admiration for both Noelle and Queen, helps the latter with her plans.

Kris and Susie convince Berdly to change sides, but he is intercepted and captured by Queen, who forces the party into a fight. After Berdly is freed, Queen flees the area. She delivers a soliloquy about the nature of Dark Fountains, revealing that any inhabitant of the light world can open one through the use of "Determination". She attacks with a giant robot, leading to a final battle reminiscent of . Queen manages to defeat the group and threatens to kill them if Noelle doesn't follow her plans, but Noelle snaps at Queen and tells her she is done being controlled. Realizing the error of her ways, Queen tells Noelle to create the world she wants. Berdly then attempts to create a Dark Fountain, but Ralsei warns him and the rest of "The Roaring"—a cataclysmic event caused by the opening of too many Fountains. Noelle thanks Susie for rescuing her, wanting to form a relationship. Kris closes the new Dark Fountain, and Queen and her followers relocate to Ralsei's Dark World.

Kris and Susie awaken in the computer lab with Noelle and Berdly, who are convinced that their adventure was a dream. Susie walks Kris back home and is invited in by Kris's mother Toriel. In the bathroom, Kris tears out their soul again and climbs out a window. After Kris returns and puts their soul back in their body, Toriel discovers that her car's tires have been slashed, calls the police, and suggests that Susie spend the night. After Toriel and Susie have fallen asleep, Kris rips out their soul again, turns on the living room TV, and uses their knife to open what appears to be a Dark Fountain in the living room. The screen fades to black, and a smile appears on the static of the TV screen.
