どこまでも続くように見える「沈黙の海」 Silent Sea Blue sea, nothing is there. It was once filled with the songs of living things so loud that I even wanted to cover my ears. But now, there is only the blue sea and I can hear nothing any more. Creatures called human beings only consider about themselves. While as the days pass by the songs of the living things die away one after another, and are gone. so now I can hear nothing any more. There is only the silent blue sea.
