AIKa

Much of the world lies underwater, making salvage work both valuable and dangerous. Aika Sumeragi retrieves what the flooded cities have left behind, relying on combat training and an unusual power that makes her far more formidable than an ordinary diver.

A lucrative job sends her after the mysterious Lagu. Rival seekers turn the assignment into a battle against an armed organization whose plans for that power extend well beyond profit.
