Shinichi was not excited. He'd thought they were just going to show their abilities to the instructors in a controlled environment, but capture the flag? And they were expected to fight? Someone could get seriously hurt! Well, Shinichi couldn't, but the others didn't have his regeneration.
While his team was forming a plan, Shinichi continued lamenting the situation. Before he realized it, they had started. Shinichi decided to head off into the woods. Hopefully he could just wait until the game was over without encountering anyone.
Shinichi's hopes were quickly dashed when he spotted a person walking in his general direction, towards his team's flag. And it was just Shinichi's luck that it was the guy who had created the sword earlier, in his attempt to spar with Akiko. He could probably soundly beat Shinichi in a fight. However, he hadn't seen Shinichi yet. Maybe Shinichi could get the drop on him, and knock him out with one punch.
With his plan set, Shinichi waited for the guy to get near then leaped out, bringing his energy to his fists and launching a strengthened punch towards the boy's chest.
