In a future where memories can be deleted and stored, Silence is a top memory cleaner, dealing with the painful past of his clients day after day. He was as calm and numb as a precise instrument. Until one day, he discovered a ghost fragment that belonged to no one in a piece of data to be destroyed. A girl playing a mysterious melody. The fragment invaded his reality like a virus, awakening his buried perceptions. In order to pursue the truth, Silence must sneak into the Forgotten Sea, a forbidden land where countless abandoned memories are stored, fight against the huge technological empire he serves, and finally face a cruel secret buried by his own hands.
