A former student of The Academy, an advanced school in the big city for only the brightest of students. After being forced out, he finds himself living back in the tiny coastal town his grandmother called home.

Having lost his mother and his leg at a young age in an accident, he finds himself stricken with terror when forced into dark, silent spaces.

In order to obtain the money for an advanced cybernetic leg, he buys into a plan to salvage a hidden treasure from his grandmother's sunken storehouse.

In the near future, a sudden and unexplained sea rise has left much of human civilization underwater. Ikaruga Natsuki, a boy who lost his mother and one of his legs in an accident some years earlier, returns disillusioned from a harsh life in the big city to find his old countryside home half-swallowed by the sea. Left without a family, all he has to his name is the ship and submarine left to him by his oceanologist grandmother, and her debts. His only hope to restore the dreams for the future that he has lost is to take up an opportunity presented to him by the suspicious debt collector Catherine. They set sail to search the sunken ruins of his grandmother's laboratory in order to find a treasure rumor says she left there. But what they find is not riches or jewels; it is a strange girl lying asleep in a coffin at the bottom of the sea, Atri. Atri is a robot, but her appearance and her wealth of emotions would fool anyone into thinking she's a living, breathing human being. In gratitude for being salvaged, she makes a declaration to Natsuki.
