150 Years after the Great Nirvana erased human memory, the world is a "silent land" composed of high-tech ruins and quicksand. Karen, a young scavenger, possesses a mysterious ability to read the "echoes" of objects. When he comes into contact with a relic belonging to his missing sister, a terrifying memory draws him into a conspiracy that spans centuries.
The journey to pursue the truth is a desperate journey against the entire world. The ruling class "Archivers" regard him as a virus that must be eliminated, and the ruthless hunter "Silent Dog" follows him everywhere. His only hope is to find the legendary "Echo Weaver" who also has the power of "resonance".
From personal revenge to uncovering the truth behind the destruction of the world, Karen must learn to harness her power in the flood of memories. He will "walk" in the past, witness the disaster that ended civilization, and finally face a cruel choice in the "Core of Annihilation": save his only remaining relatives, or save this world built on lies?
When the silence is broken, do you dare to listen to the true voice of history?
