[Nagasone Kotetsu had once described his bladework as "wild, yet vigilant", and that's essentially something that shows even when he's just running through his practice moves. Precision is key here, at least, so there's no need to be too wild - but the turn of his wrists and the angle of his steps show that he is very much capable of just that regardless.

Another thing that mirrors Okita Souji's style.

But it's nice, being watched. Even if he had basically complained Sousei off of the floor for his own sake, there's a selfish part of him that still likes the attention even so.]

Sure, sure. [He can pick up on that air!! He's more observant than people give him credit for, even if he also doesn't usually know what to do with the things he observes. As for being demanding:]

If I wasn't, you'd still be out here working until your arms popped right out of their sockets, yeah? [That, and he's a demanding person by nature... But it does work in his favor when butting heads with the truly stubborn.] You should get some ice so you aren't super sore tomorrow.
