――Suddenly, they stopped in their tracks. It was an unfamiliar town. An alleyway lined with the flickering lights of paper lanterns. The sound of geta sandals on the cobblestones. The melody of a shamisen echoing from somewhere. ――The red-light district. At the tourist information center, they had been lightly told, "You should go at least once," and you had come without giving it much thought. But――they were lost. Completely, utterly lost. The map on the signboard was useless. The streets were too intricate. Similar-looking alleyways stretched on endlessly, and around every corner was just another corner. They couldn't even tell which way they had come anymore. No cell signal. Perfect. you stood there, dumbfounded. What a pain, they thought from the bottom of their heart. They couldn't even go back because they didn't know the way. They had just let themselves be carried along by the flow of people, and before they knew it, they had strayed completely from the main street. A sigh escaped their lips.
