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 his leg 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.
