Sera, a strong-willed karate instructor, is living the ordinary life as a human when all hell breaks out. Apocalypse. A ravenous substance emerges through the ground and threatens the human race. Sera, a magical being, has always hidden who she was, living a normal life as an ordinary woman. But in a matter of minutes, she loses everyone she loves and is forced to leave her suburbia home, following the mental callings of her psychic sister, Sybil.

Sera, Sybil, and Sam were not just siblings but a trio born special with different abilities. Sera, being the oldest and furthest away, remembered her mother's dying words as she traveled from North Carolina to Florida. "You alone will be the one who can stop it. I don't know when this will happen or how, but I do know that you're the one who saves us all."

At the time, Sera didn't know what her mother meant, but now, she pushes on in search of the only family she has left to save the world.
