Devero has to pause for a moment so he can tell Koumyou, "I'd like that."

Technically, he already knows martial arts-- well, a martial art, the Tri-Delta defensive art developed by the World Guard. He's rusty as hell, but the sparring session with Trunks and then the fighting during the mission has started shaking that rust loose.

"Everything I know already is focused on defense, and disarming your opponent," he tells Koumyou. "To be able to move like you would be... incredible."

He leads them back into the dance-- "Just do the main steps again, it'll be about four repetitions--" before reinforcing the caveat: "If the magic lessons go well."
