Riku had little clue how far or where the lasers could penetrate. He hadn't known the guns were apparently water proof. As such, he took every shot he could, simply hoping the water wouldn't mess up his shot. Riku may not have been able to hide, but neither could Sora. For now it'd be a game to see who'd decide to move out first.

Sora kept Riku on his toes, as it were, since Sora always was the faster swimmer. His leaner form was easier to move through the water. Riku, however, could use his muscles to change direction faster, making him slightly more agile. For Sora, it would be a matter of watching where Riku was heading to get a shot. Riku had to predict where Sora would be in the water and aim accordingly, trying to keep up.

Riku felt a bit of a twinge in his side. The bandages were worthless, and now it was a matter of trying to see how long he could last without them.
