Will you survive in the future world? This is the beginning song. The trivial events we chose that day made us now, and the drama continues to this day. As long as I am alive, there are many times when I hit a wall and want to escape. But remember. Haven't we always overcome it many times? I want you to remember the feeling of accomplishment when you pierced the wall, remembering your past self who took a step forward with courage, clasping your trembling fist. This is a song that gives me strength from my past self. Believe that the answer lies beyond that.
