Umm... Well, Lili-chan chooses who participates in the concours every couple of years, and some of them didn't exactly consent to it...?

[Kahoko eventually went along with it, but Tsuchiura seemed to resent every second he had to spend in the company of the other Music School participants. He only put up with Kazuki, for the same reasons as cited above. You really can't hate the guy.]
