Adagio wants to blow off some steam after the small issue of losing her magic, the ability to sing, and being humiliated in front of an entire school. She finds the perfect way of going about this is the time honored tradition of punching your problems out: boxing. While Aria passes on the idea, Sonata is more than happy to help out Adagio.
The only problem is Adagio only gets more frustrated when she sees Sonata after changing for their workout.
One-shot.
