If you're talking to yourself already, you might as well take a real sparring partner.

[A significantly less practiced, but still serviceable swing of a naginata knocks the head off the the dummy, and the bulky thing lists to one side to reveal a golden-eyed boy behind it, lowering the weapon in question. He looks skinny on first glance, but without the coat that usually covers his arms, the wiry muscle that lines them is visible as he gestures to her with the polearm.]

You look like you know what you're doing with that thing. [Shun hasn't trained with a polearm user for a while, and considering he only started learning it relatively recently, he feels he could use the brush-up that sparring with someone with a heavy experience advantage provides.]
