Trillion: God of Destruction

More than a thousand years passed since the legendary battle against the Heavens. The demons of the Underworld lived an evil, yet fulfilling life in peace. And so it remained, until the appearance of Trillion, a demon god of destruction that sought to consume the world. Its power unfathomable, it destroyed the Underworld’s forces. Even Zeabolos, the Great Overlord himself, was defeated. On the brink of death, Zeabolos heard a mysterious voice from deep within. “It is too early yet for the lineage of the Great Overlord to fall…” Zeabolos was revived, his shambled body patched together again by a young necromancer named Faust. Zeabolos gained the power of the Soul Grimoire, and decided henceforth to fight.

"The Underworld---The denizens of the Underworld lived a free life amid conflict against the Heavens. There arrived a mysterious threat, a giant evil creature. This is the "God of Destruction." The eater of worlds... The Underworld is at a loss against its tremendous power. Even the mighty Great Overlord Zeabolos falls against its greatness. Near the brink of death, Zeabolos hears a mysterious voice... "Are you willing to offer your very soul to defeat it?" The moment Zeabolos agreed, he revived into a patch worked body. And thus, Zeabolos rises once again with the mysterious girl, Faust, at his side, to face Trillion. Train the Overlords as candidates to be the next Great Overlord, and to defeat the God of Destruction!"
