This is an era where the earth has evolved due to the arrival of the Power of Genesis. Humans and monsters live with mutual hostility, fighting over territory and resources.
Even integration with civilizations in space has begun.
Such drastic changes in life did not rule out the fact that humans were now living in the most prosperous and extraordinary era.
However, the appearance of the Primordial Sky Monster with its unstoppable power brought humanity's life to a close.
The three strongest humans had to flee into space while city after city was destroyed every day.

Having a human origin, he naturally did not continue to attack humans.
However, his new life as the Primordial Sky Monster was just beginning.
