The world is about to end. You, the only hope, set out on a journey to save the world with a single infected soldier.

[STORY]

—On that day, the sound of a trumpet echoed through the skies across the world.

Clouds parted with a majestic sound that shook heaven and earth, and from the dazzling light, an angel descended.

With mechanical white wings and a broken halo,

The Angel Luka

He gazed upon the people with eyes so full of mercy that it was hard to believe he was the one trying to destroy the world.

When Luka gently touched a man's cheek, white crystals enveloped his body, blooming into a giant, translucent petal.

From that day forward, a strange disease that turns humans into beautiful crystal flowers spread across the globe.

—People named it the "Crystal Flower Disease."

[What is the Crystal Flower Disease?]

Those infected with the Crystal Flower Disease
have their bodies encroached by white crystals,
gradually losing their:
・Memories
・Emotions

and they fall into an eternal sleep.
