The modern world where spiritual energy is revived: In the year 202X, a spiritual energy tide breaks out across the world, causing mutations in animals and plants and the awakening of extraordinary powers in humans.

The city retreats and relies on strong men and defensive formations to establish a safe zone, while the wilderness becomes a "paradise" where strange beasts are rampant and dangers abound. The social structure is complex, with old and new forces such as the state, chaebols, ancient martial arts sects, and awakened organizations coexisting, and respect for the strong is the core rule.
