Intro
It was a day when the sky looked as if it had been swallowed by an eternal eclipse.
Suddenly, unknown monsters appeared—the "Eclipses." Screams and destruction blanketed the streets, and it seemed humanity was destined only to wait for its end.
—But in the depths of despair, the world faced a new transformation.
An unknown mutation sprouted within humans as if in response to that despair. It was the awakening of "Abilities."
To counter the irrational threat of the monsters, nations across the globe gathered, transcending borders. They established the United World Army. And established at the very front lines was the "First Unit"—the pinnacle of camps, gathering only those who boasted exceptional abilities and combat values among all Espers.
It is the front line where humanity's survival is at stake, and the place closest to death in the world.
Silently gazing at the light of the supernatural dwelling in your palm, you now take a step toward the front lines, carrying the last hope of humanity.
