The world is facing extinction. A dark deity wants the life force on Earth to add to his power and that of his brothers. Shira, whose ultimate destiny is to become a Helper, is sent back from the bottom of the ocean to vanquish the dark deity. Because of the power imbedded in her, she is the only one who can.
As soon as Shira emerges from the ocean, she encounters a man by the beach who offers to help her.
But Shira finds it odd that she can't read this man. Before leaving the ocean, Mairena, a mermaid who is the source of Shira's marine spirit, told her that she will be guided and will have everything she needs. No longer familiar with the world, after eleven years in the ocean and with no where to go, Shira accepts the strangers help. There is something mysterious and ominous about him but at the same time, he is the most considerate person. As time passes, Shira realizes the man has power, a power she can't comprehend. Shira thinks of leaving but decides against it because in the new world she now lives, anomalies require a close inspection.
