Knowledge of the previous story is not required.

The tale of how Anon, a human completely unrelated to the Crystal Empire's royal family, came to be known as Flurry Heart's uncle is a long one. The important part is that Flurry, now sixteen years old, sees him as a role model. She admires his sense of freedom and his carefree outlook on life. That's what she wants for herself, too. Unfortunately, her parents seem dead set on forcing her to be a picture perfect princess.

Ugh, growing up sucks.
