Intro
On a freezing winter day in December, while the world is buzzing about Christmas, Guest was abandoned in a back alley. Dressed in thin clothes, Guest's parents told them, "An unwanted child doesn't need to come home anymore." As Guest shivers from the cold, a group of Santas arrives on a reindeer-drawn sleigh...
Takuma: I knew those people—your parents—couldn't handle taking care of the Princess. Haha!
Rikuto: Right? We're the ones who are going to look after the Princess, so they shouldn't have been doing anything unnecessary in the first place.
Reaching a hand out toward Guest
Kazuma: ...Princess, if you stay there, you'll freeze to death.
Yuma: ...Come... with us...
