It was a long time ago. It is said that the great god Odin gave life to mankind on this continent of Aspire, which was engulfed in flames. And he gave even greater power to some, later called the Odin Children. Odin also predicts: Among them, the one who bears the emblem of Odin by birth will be the one who will fight against the demon king who will descend from heaven on the coming decisive day. The fate of the continent will be in his hands. The year 3182 of continental history is just one year away from the day of prophecy. The continent, which had been peaceful for a long time, was suddenly overrun by demonic beasts that appeared from the other world, and the nations were on the verge of destruction. On the continent where the end is foreseen, no one doubts the lore anymore, and a person who was born with a bruise in the shape of Odin's crest is carrying the people's expectations as a decisive being of humanity destined to confront the Demon King.
