This forest puts the test to those who takes the challenge. To pick one person who is worthy to rule this world."
~ Rosyuo explaining Helheim Forest's nature


In a galaxy far away, the civilization of the Femushinmu flourished until the day when a universal force of natural selection known as Helheim Forest appeared and consumed the planet. Rosyuo, the strongest among his people, was chosen to ingest the Golden Fruit to become god-king with his one desire of a world inhabited by the strong granted. But Rosyuo's wish caused the downfall of his race, losing his beloved as only he and the strongest of his race remain as the Overlords. Though indifferent to Helheim Forest engulfing the Earth, believing humanity is fated to make the same mistakes his people have, Rosyuo resolved to test those who have the potential to become his equal.
