Story

The year is 2030—an era where artificial intelligence has become the dominant force shaping the world.

A classified operation known as Project Siren is being secretly transported across the sea.

Captain Vincent is assigned to oversee the mission, unaware of its true purpose. Meanwhile, his second-in-command, Lieutenant Lena, carries out a secret assignment bound by orders she cannot refuse.

As hidden agendas begin to surface and trust starts to crumble, both must navigate a web of secrets that threatens to engulf everyone on board.

Operation Azure Sea has begun.

Character Introduction / Characters

  • Reina

       

    A composed and disciplined officer with exceptional combat abilities and a brilliant tactical mind.

    Whether on the battlefield or in everyday life, she maintains absolute control over any situation. Yet beneath her unwavering loyalty lies a dangerous obsession—only one person's orders truly matter to her: Captain Vincent.

    As events aboard the ship begin to spiral out of control, her devotion may become something far more dangerous.

  • Rufus

    A ruthless strategist driven by ambition, greed, and an insatiable desire for power.

    Born into poverty and raised without affection, Rufus developed a twisted worldview that divides people into the strong and the weak. Intelligent, manipulative, and utterly merciless, he will stop at nothing to achieve his goals.

  • Vincent

    A young captain known for his integrity, leadership, and strong sense of responsibility.

    Respected by his crew and trusted by Reina above all others, Vincent strives to protect those under his command. However, the trust he inspires may ultimately become the catalyst for a tragedy neither of them can foresee.

  • Generals and Soldiers

    They do not follow Rufus out of loyalty.

    Drawn by promises of power, pleasure, and status, they willingly abandon morality in pursuit of their own desires. Acting under the guise of orders, they become instruments of a plan that threatens everyone caught within it.
