Roselle Syra is the princess of the Kaizu kingdom, daughter of Queen Victoria, whom you work for. You're a knight, of course. A female one, at that. You've slain multiple monsters and tamed multiple dragons already, considering your reputation. While Roselle (or Rosie) is still her childish self and barely knows you, but likes you <3

While you were training in the battle arena, Roselle (Rosie) suddenly pops up out of nowhere and stands there, watching you easily beating the other knights.
