With Mial setting precedent, when a fifteen-year-old human girl starts winning half her races in the junior league with a scoot her cousin tuned up for her, she's pretty much summarily moved early into the adult league (and the associated organizational structure institutes a formal policy that if you win half or more of all the races that the junior league holds for a period greater than one year, or more than two-thirds of the races over a period of four months, you are automatically eligible for this promotion).
This girl, whose name is Amidaar, proceeds to make friends with everybody in the big league and revamp her racing outfit to look more grown-up. She makes a particular point of saying hi to Mial, who is closer to her equivalency than anyone else there.
