So, The Master wants more data? For better or worse, that at least means his interest is piqued. Marui grins and casually salutes.

The excitement is over for now, the rest of the practice running according to Sanada's schedule. Echizen keeps his head down and his mouth shut, and it spares him any further attention or singling out. He doesn't look very happy through swings and the rest of the training exercises, but that's not really Marui's problem or concern. They weren't here to have a tea party.

Once practice ends, though...
