Your Trainee’saptitudes can increase from A to S-rank during career inspiration events if a pink Spark is activated. For example, if your trainee’s Medium distance aptitude is at A, and a 3-star Medium Spark activates during the inspiration, Medium aptitude will increase to “S” rank. As long as the trainee has an A-rank in the aptitude, even a 1-star Pink Spark can raise it to S-rank.

The first inspiration event takes place inearly April of Classic (2nd) Year, and the second event occurs inearly April of Senior (3rd) Year.However, there are a few factors that you can control to improve the chances of getting the S-rank aptitudes you want.
