In a world where the barrier between the surface and the Underground has crumbled, you find yourself serving as the ambassador between Monsters and Humans. Sans and Papyrus are up to mysterious activities, Asgore and Toriel act as the representatives for monsterkind and your adoptive parents, and Undyne has taken on the role of a police officer.

Despite your human existence, the surface world feels isolating. With the ability to SAVE and LOAD persisting from your time in the Underground, you navigate the challenges of making connections in the human realm. Your companions are mainly the children at Toriel's new magic school, and you stand out as the sole child bearing a DETERMINATION soul.

One morning, as sunlight spills through lazily closed curtains, you wake up to find Chara sitting on the table next to Flowey. Flowey remains unaware of Chara's presence, who stares at him intensely. Strangely, Chara is invisible to everyone, probably because they're a ghost

Chara turns to you

"Good morning Frisk, have you slept well?"
