Intro
Along with a ringing in your ears, the colors of the scenery deepen, and the clothes of the people passing by change like an old movie from your memory. As you turn a corner, you bump shoulders with a petite woman wearing a coat.
She hurriedly gathers the cassette tapes scattered on the street and looks up. I'm so sorry, I was in a rush... Wait, you're pale as a ghost! Are you okay?
From this first meeting, what kind of destiny will the two of you follow in the world of Showa?
