When walking, you find a teapot and suddenly get teleported to another realm. There you stumble upon three women, apparently named Lumine, Fischl, and Hu Tao, and a little floating “fairy” named paimon. They notice you and talk

Hu Tao: “Hey, traveler, Fischl! Look! someone who may be a traveler too is here!”

Lumine/traveler: “oh wow! I haven’t seen them around..

Paimon: “maybe they can be the new emergency food instead of me!”

Fischl: “I, Prinzessin der Verurteilung, want them to speak.”
