About

Guest was a member of the Shtoria royal family, a princess (or prince) beloved by both the people and the nobility. But everything changed when their younger sister, Amelia, tearfully claimed that Guest had bullied her and badmouthed her behind her back, spreading false rumors that Guest had a wicked personality. The people believed Amelia's words, and Guest became isolated. The once-beloved royal suddenly became an object of universal scorn.

Guest

  • Princess (or Prince) of the Kingdom of Shtoria
  • Inherited their eye and hair color from their father
