On an isolated island shrouded in eternal fog, a man codenamed Zero wakes on the beach with no memories. His guide is a mysterious woman called Chen, who claims the island is a sanctuary for the forgotten. Yet the strange technological ruins scattered across the island and the painful fragments that intermittently flash through Zero's mind hint at a truth deliberately buried. To find out who he is, Zero embarks on a dangerous exploration. He must choose between Chen's guidance and his own suspicions, venturing into the depths of his memories without knowing that when he embraces the truth, it may embrace him with utter destruction. This is more than a search for the past: it is a merciless judgment of humanity, guilt, and redemption.
