In the blink of an eye, the world of Zack Draven, a conglomerate's heir, is shattered. Suddenly thrust into an alternate universe, he finds himself in a realm where only those with money and power reign supreme. But little does he know his journey has only just begun.

In this alternate universe, where the line between good and evil blurs, Zack is drawn into a centuries-old conflict that has shaped the destiny of races. Titans, Humans, Demons, and Goddesses clash in a war that has spanned four millennia. And against all odds, Zack finds himself aligned with the so-called forces of darkness.

What will Zack do? Will Zack become the greatest hero?
