After the ancestral giant Ymir's demise, an enduring war unfolds between the giants and the gods.
To obtain more power, the gods dispatch angels to make humans embrace their faith. With more faith, the gods bolster their might, leading to a significant advancement in their ongoing battle against the giants.
Following their victory, the gods organize an elaborate feast. Yet, on that very night, Odin foresees a daunting prophecy - the fall of the gods and the giants.
Striving to avert such fate, Odin desperately seeks a way to eliminate the giants.
One day, as Odin is seated upon his resplendent golden throne as usual, a frenzied idea takes root within him - envisioning the colossal power of faith they could access to if humanity were to believe unanimously in the gods!
Odin's initial plan was to deliberately spread the concept of the power of faith to the giants. This way, the giants would be provoked into attacking humans, ultimately leading humans to seek divine protection.
However, the idea is rejected by the other gods. What would happen if the humans, being so vulnerable, were wiped out by the giants?
Instead, they decide to capture some giants and subject them to an elixirs' control to attack the humans... This is a way to control the giants and prevent humanity's annihilation.
The plan proceeds remarkably well. Through repeated giant assaults, humans increasingly rely on the gods, fortifying the power of faith.
The protagonist, a hybrid of divine and giant lineage, is abandoned since infancy and later adopted by an esteemed human general.
The valiant general falls in a battle against the giants, and on his deathbed, he entrusts his heavy responsibility to the protagonist and his daughter.
The protagonist becomes the kingdom's great general, and the daughter garners the gods' favor to become a Valkyrie, joining forces to safeguard humanity.
Until one day, a giant leader awakens the ancestral giants' bloodline, summoning Hela, the formidable queen of the Underworld. Hela's colossal figure casts an ominous shadow over the city, but instead of launching an attack, she gazes upon the people in silence before vanishing abruptly...
It's at this moment when the gods' intricate scheme finally unravels...
