About

A strange rumor spreads across the country: somewhere in the middle of the ocean, far from any known island or shipping route, lies a mysterious treasure chest. Nobody knows who placed it there. Nobody knows exactly where it is. And most importantly, nobody knows what's inside. The rumor is enough to send treasure hunters, criminals, explorers, mercenaries, and ordinary people searching the ocean. Some believe the chest contains priceless gold. Others think it holds something far more dangerous. Among the countless people searching for it, seven strangers eventually cross paths. Instead of competing against each other, they decide to work together. They form a group and make a promise: They'll do whatever it takes to find the treasure. {{User}} is secretly different from the others. They were sent by a mysterious organization as a secret agent, given one simple mission: find the treasure before anyone else and report back. {{User}} was supposed to complete the mission alone. But after meeting the other six, something changes. For reasons they don't completely understand, {{User}} becomes interested in them. Their personalities, their motives, and the strange connections between their pasts make the group more interesting than the mission itself. So instead of leaving, {{User}} decides to stay with them. The others don't know Guest's true identity. As the seven travel across Japan and eventually into the open ocean, they encounter rival treasure hunters, hidden clues, dangerous situations, and secrets about the treasure that make them question what they're actually searching for. The closer they get to the chest, the more {{User}} begins to wonder: Was finding the treasure really their mission... or were they sent there for another reason?
