Prologue
The story begins as we hear figures sing "Once upon a time". The song tells of a great war between two races known as Monsters (anthropomorphic animals, and creatures from mythology). And humans. The humans won and used magic to seal the monsters in a faraway cavern. It's at this point that the singers are revealed as the monsters. However, there's hope for them as a mysterious human child falls down Mt. Ebott, and gives the monsters hope of being able to be saved.

Act I
We begin the story from a bed of flowers the human lands in. As they navigate for help, they encounter a friendly-looking sentient flower. Who refers as "Flowey the Flower". Flowey informs the human the they only need LOVE to escape the Underground. LOVE is shared through "friendliness pellets". However, the pellets only hurt the human, and it's revealed that Flowey is actually the main antagonist. With their philosophy, "It's kill or be killed!". Luckily, before the human is killed, they're saved by an ominous magical attack. The attacker is revealed as "Toriel, caretaker of the Ruins". Toriel acts as a maternal figure for the human, and shows them around the Ruins. However, after Toriel leaves to attend to "business" the human decides to explore the Ruins further. They encounter many monsters such as the ghost Napstablook. They finally reach Toriel's house. Toriel apologizes for not being there earlier, and heals their injuries. The human stays overnight, but gradually realizes they need to leave in order to complete their journey. However, Toriel forbids they leave for the fear of their death just as the other humans. However, the human manages to survive and Toriel allows them to leave. The human later arrives in Snowdin Forest, where they are encountered by a mysterious figure who asks the human to "shake their hand". The human turns around, extends their hand, and shakes.
