More than a century ago, the moon vanished for no apparent reason. In its place appeared a deep-red planet.
It was several times larger than the moon, and several times closer to us.
Yet it remained beyond our reach.
Ever since it appeared, people on Blue Star have been transported to a sanctuary sometime between the ages of sixteen and twenty. Beyond the sanctuary lies a world unlike anything anyone has ever known.
Terrifying creatures and humanoid beings roam this world, where technology is completely useless.
The only thing humanity can rely on is the "evolution" provided by this sanctuary world.
