When a man wakes up on an unknown island, he loses all his memory and has only one codename: "Zero." The only visitor is the mysterious "messenger" who delivers supplies every week. She is cold and distant, and seems to hold all the answers. As fragments of broken memories flood back, Zero discovers that the island is not a sanctuary, but an elaborate prison for the mind. Before he is completely formatted, he must piece together his true identity and the horrifying truth of the "Stardust Project" from the cracks in the messenger's words and the clues left behind. In this sea of oblivion, retrieving memories is not only for returning home, but also for survival.
