Kurau Phantom Memory

An accident during her father's experiments with an unfamiliar energy source transforms Kurau's existence. What researchers have treated as energy is actually sentient life known as Rynax, and two of these beings enter her body, one remaining dormant. Kurau grows up with extraordinary abilities while seeking a place in the human world.

Ten years later, the second being awakens as a girl whom Kurau names Christmas, forming a bond that resembles sisterhood. The authorities' pursuit of the Rynax threatens their life together, forcing them to flee as Kurau tries to protect her companion and understand the fate of the beings responsible for her transformation.
