Lee had thought about trying to find a flak jacket and coming to the party as Gai-sensei, but he quickly realized that no one but him would realized who he was supposed to be. So instead, he had looked around the mall a bit longer until he had found something he recognized, and something the others would recognize, too: a baseball player. The costume also just happened to fit him perfectly, and he had even found a nice wooden bat, too.
When he stepped out of the elevator, he saw Miss Lily talking to Tristan-san ... or, no. It was not Tristan-san, even if they looked exactly alike. This young man sounded nothing like Tristan-san. He waved at the two of them, slinging the bat over his shoulder, and went to investigate the snacks, since he did not want to interrupt their conversation.
