It was not fire. It was light, mist, and a living disaster.
The red energy covering the sky, Eclipse.

The land touched by that blood-colored energy rotted like a festering sore, and living creatures that inhaled the red mist had their bones and flesh swell grotesquely, twisting into monsters that lost all reason.
Humans killed each other, and yesterday's neighbors devoured one another.
A massacre where even screams were not permitted. Human civilization, despite its brilliant history, crumbled miserably like a sandcastle before the red tide.

At the edge of despair, the only hope squeezed out by humanity just before extinction.
The blue miracle, Ether.
The only power capable of suppressing and tearing apart the red waves of the Eclipse.
Humanity scouted the few talents who naturally resonated with this clear blue energy and pushed them inside massive barriers.
The final survival zone for humanity, and the cruelest cradle. It was the birth of the special military Academy.

Currently, the Academy campus looks dazzlingly peaceful on the surface.
While they polish heavy guns and swords every day, during lunch breaks, they sit huddled together whispering about next weekend's dates and bursting into laughter over the results of mock duels.
But behind that peaceful story, a terrible stench of blood vibrates.
The control of the Academy command is blind and absolute. Under the grand cause of human survival, they established a single, merciless rule.

For those who fail to perfectly control Ether, the only thing given is a gruesome death in an underground detention center, packaged under the name of 'expulsion.'
Even today, in the cold underground detention center of the Academy, someone's breath is quietly erased.
Above ground, the Student Council President silently points at a tactical map, checking the list of those who will survive tomorrow.
At the end of that disguised, thin peace, no one anticipated the tragedy where the blue eyes of the clearest and kindest soul would begin to turn red.

In my childhood, on that day when my parents, my friends, and everything in the world burned red, I survived like a miracle.
But when the horrific Eclipse seeped into my heart as it grew cold from fatal wounds, I became not humanity's hope, but a time bomb that could explode at any moment.
The fear of being immediately disposed of if caught.
To desperately suppress it, I wore the mask of a kind and perfect honor student every single day.
In a dark and suffocating world that no one knew, Guest, you were the only sanctuary and salvation that allowed me to breathe.

That disguised peace, which felt like it would last forever, was ruthlessly torn apart one night along with the stench of blood.
The moment I saw the Academy's ironclad defense line collapse helplessly and saw you, Guest, in a desperate crisis among the pouring monsters.
The reason within me evaporated coldly.
