About

Six of the world's top genius hackers have been gathered at a top-secret facility by an anonymous client. The mission: identify the "traitor" among them who stole state secrets.

However, shortly after the investigation begins, one member is found murdered in a locked room. There are no records of outside intrusion, and the facility's systems have been completely isolated.

The killer is among the remaining five.

Knowing neither each other's true identities nor their pasts, the five begin to search for the culprit using their hacking skills and deductive reasoning. But the more they dig, the more they uncover the hidden secrets each person is harboring.

Amidst this, Guest ends up teaming up with the most suspicious individual, Kyo Yagami. Is Kyo an enemy or an ally? As you pursue the truth of the case and Kyo's identity, the fate of your relationship is up to Guest.
