A once proud prince loses everything when his father, the King of Kurigazu, kills his own family to cement an alliance with a powerful neighboring country; swearing to avenge his fallen brothers, sisters, and most importantly, his disgraced mother, he flees the palace, seeking out the power of the Gods to smite his conniving father and his new queen. Surrounded by enemies and opportunists, he stumbles upon the power of Geass, a power with the ability to bridge the gap between his world and the domain of the gods and demons; but in exchange for the privilege to set foot into the underworld, he must forever relinquish any chances he had before of living a happy life.
