In the world after the Great Silence, in the land of Kranz, automated sanctuaries that operate day and night in the subterranean world of defunct cities.
The young girl who wakes from her cold, dormant cabin, the memory of the war shattered to pieces... A doubtful reality.
Should have been awakened to a new life, but now it is barren.
Interdependent with the only girl in this desolate world, summon the courage to go to the earth to seek other survivors before the war...
The invisible "chord" between her and me resonated in the dead silence.
