You could tell, in a spar, when your partner made a mistake. There was a moment when the fluid motion would suddenly check or stutter. When an opening that shouldn't have been there was suddenly available. If you saw your sparring partner's face at just that moment, you'd see a sort of horrified realization pass through his eyes, and you'd know. He just fucked up, and he knows he fucked up. And then if he was good, like Raidou was good, for example, he'd turn that mistake into some other move.

Genma saw the mistake.

The thing about a mistake like that, in a real battle, where lives were on the line, if the enemy you were fighting made a mistake and you saw that look on their face, you struck. But in a spar with a peer, if you saw that look and struck, well, it bordered on the dishonorable.

Genma's eyes flicked over the menu quickly until he spotted another prawn dish. Four chilies this time. "I don't know," he said as if he'd only proposed the Mangrove Spicy Prawns as a very tentative idea. "Maybe this Sweet Treasures Spicy Prawns and Lobster would be better. I mean it has lobster. And it's fifteen ryou more, so it's probably better ingredients. Maybe we should get that one instead." He looked up at Raidou over the menu with an apologetic smile. "Although if you really have your heart set on the Mangrove Prawns, I'm sure they're awesome too."
