@Chrona I agree with you that the "Pixie" thing could have easily been foreshadowed better, but we've known that they needed to raise their ranks to 4 and about the Music Festival, since before the Harvest Festival.
Did I ever suggest otherwise? Unless you're critiquing me specifying the music competition as only be revealed 3 chapters ago. Which while you are correct that it's been known for a while that they need to increase their rank, it hadn't been specified until now that it would be music related, and that one of the problem students happens to be a famous musician.
