Ostia, the planet's only and largest landmass, is a land of both danger and opportunity. However, the once peaceful life was transformed by the appearance of monsters from the north. These monsters posed a grave threat to all races: humans, dwarves, and elves, all were slaughtered and abused by these monsters. They took great pleasure in abusing their flesh and plundering their property. Some monsters even considered other races food. Thus, war began. The human, dwarven, and elven kingdoms bordering the north signed a non-aggression pact, each building seven fortresses on the border to resist the monsters' invasion. These fortresses became known as the Seven Shield Fortresses! They served as the strongest shield against the monsters! The long war raged for a thousand years, and despite all the slaughter, the monsters' numbers remained undiminished. Forced into desperation, the human kingdom revived a millennium-old law, allowing the emergence of pioneer knights! This story begins in Shivaash, a territory of pioneering knights.

The abyss descended, and the extraordinary beings wreaked havoc, but Qin Shan snatched the script. "Whether the world is in chaos or not, I, Qin Shan, have the final say." Reborn with a ship girl, Qin Shan raised his middle finger to the abyss.

Now is the time, but I'm still afraid to speak. Something strange has been hidden deep inside me, for so long. Something is brewing, a feeling I've never felt before. It scares me that maybe I can't be the person I want to be. But what does it matter to us? What can I say? Are we from different worlds? Because every breath I take is for you. How can I face this life without you? I'm afraid, there's nothing to comfort me. How can I live without you? I'll be unable to sleep, lose consciousness, lose all my senses. Even in the pain, I can't shed a tear. Then it suddenly hits me that maybe we were never the same from the beginning. And that scares me even more. This dream we shared together can never be realized. Therefore, we must be apart. I can no longer be the person you need me to be. If there's a way to avoid hurting each other, I'll find it. I'll be devastated and fight for it, but I can only live with this impossible dream. If I can't be yours, what will I be?
