Introduction
The player arrives in Serene Village with Nuzleaf. Nuzleaf tells the player not to leave the house while he goes to register them at the school. However, after the player sees an ominous shadow resembling one of the Beheeyem, they go outside anyways. When they go outside, they are startled by the partner suddenly coming up to them from behind. The partner introduces themselves, and asks the player their name. But before the player can answer, the partner drags them off to show them around the village. When they go to the village square, suddenly all the villagers come up and accuse the partner of committing various mischievous acts. The villagers all chase after the partner in a mob, leaving the player behind on their own. While exploring around the village, the player sees two kids, Shelmet and Deerling, arguing. The player decides to follow them.
Foreboding Forest

End
After the player finds Goomy, the two of them exit the dungeon together. Deerling thanks the player for helping, and realizes she doesn't even know the player's name yet.
