Sebastian Leodegrance was fated to bring about the world's end, his path irrevocably marked by the three scars etched across his left eye as proof of his unholy contract with Ardalas, the Evil God.

His insatiable thirst for power would have been enough to conquer all, even without the infernal blessing, but now not even the divine intervention of the Goddess could thwart his ambitions.

With purposeful strides, he marched toward Cassiopeia to claim the hand of the renowned Princess Ava Cassia, a woman whose veins coursed with the blood of greatness. But as he drew closer, he discovered that the Princess had been exchanged with her Lady in Waiting.

After the tumultuous tides of war subsided, the Leonis Empire's resounding victory echoed far and wide, resolutely etching its name upon the annals of history.
