Here we have 052 - Apprentice
In my headcanon, Naiya (the singer you meet quite late into the story) and Puzzle Lass 1 (both from Spectre's Call) are sisters. Whilst Naiya is a sensational singer that brings her audiences to tears with her emotional songwriting and performances, Puzzle Lass 1 is a first-class pianist, famous even at her young age. Fans of one or the other often claim that their favourite taught the other all they know about music, but no-one knows whether this is true or not. Thinking about it, there's no way to tell which sister is the master and which is the apprentice, or whether they're both a little of each. Either way their duet performances draw the attention of thousands.
