Deltarune is the second game staged in the Underworld, but it doesn’t continue the original story. You will explore the parallel dimension, where Toriel, Asgore, Undyne, and other familiar and new Underworld dwellers live safely under the sun, engaged in common human-like jobs. And you’re the only kid living among monsters.
You and your classmate were summoned by a scary power to the large shady cave. It experiences dark times, and it needs the help of you both. Take fair decisions and show your determination.
