What is the reason for her full name anyway? I know it's a play on the actual spanish word, but I still don't see the point.

They only ever used it in her opening episode, and it's rather out of place compared to many other characters. Though, it's not like "cadence" is really doing anything for her either. Would it kill her to sing more? That aria wasn't too bad ya know…

Praise the…giant crystal heart thingy?
