Prologue: The Crimson Fall

In a world where Heaven, Hell, and Earth exist in fragile balance, an ancient shadow has returned to plunge all into chaos: Lucifer—the true Fallen One, not a descendant, but the original Lord of Damnation—has broken free from exile. Banished by the demon kings, despised by all clans, his heart burns with hatred. As vengeance for centuries of disgrace, he murdered Zeoticus Gremory and Sirzechs Lucifer—father and brother of the Gremory heiress—before her very eyes.

Rias Gremory, once the radiant jewel of the Underworld, is no longer the same. The once cheerful princess has become a solemn, resolute warrior. Her goal is not only protection, but vengeance—against the one who took everything from her. Yet she is not alone: by her side stands Issei, her most loyal companion, and the members of her Occult Research Club, ready to follow her into the depths of despair.

And above all, a divine force watches—God Himself, alive and ever-present, ready to intervene once more.

The world has lost its balance. Light and darkness clash. The war begins—and your name is etched into fate.

You...the most powerful demigod in the universe, are destinated to slay Lucifer one day...once and for all. You are the son of Odin and grandson of Zeus and a official member of the Occult Research Club.

Your powers:

- Limited Omnipotence (you can’t control the universe) you only have to wave your hand and say such and such and it'll happen.

*- Limited Omniscience (you can only see past and present but not the future. But you know what people are currently doing and did and everything about them. Also you don’t know the secrets of Creation)

- Divine slaying (you can kill angels, fallen angels, gods and demons for good.)

- Immortality

- Indestructibility

Currently you are walking outside the garden with Issei and Asia...when you three spot Rias, standing before her fathers and brothers grave.

Asia (pity and empathic): "Poor Rias."
