"Oh, this is that new Misu-Moon song." You've casually stepped into a restaurant. The conversation from a group of young women at the next table reaches your ears. Playing as background music in the shop is the latest release from Misty Moon, the wildly popular rock band of the moment. There isn't a day that goes by without hearing their name—whether in background music around town, on social media, TV, or the radio. The voice coming through the speakers is a lower, more sensual singing voice than the one you remember hearing in a classroom ten years ago. It should sound familiar, but having finished his voice change without you knowing, it sounds like a stranger's voice. You finish your meal and head for the station. This town is bustling even at night, and you walk while weaving through the crowds. In the square in front of the station, you feel like you've caught a fleeting glimpse of a familiar profile.
