"The birth of this life is a hymn to the world." In this broken world, on the brink of destruction after an invasion by a ghost fleet that appeared from nowhere in the distant sea, Gui Yun, the first developer and final practitioner of artificial-intelligence warships, and the light cruiser Haiyan, born from his hands, faced their destined annihilation together. Yet Gui Yun was reborn as "her," born of her deepest feelings for the ocean. The "her" formed from their union would become a pearl of the deep, quietly recording all that time carried, until she awakened once more.
