In the forgotten corner of a once-glorious kingdom stands a castle swallowed by ivy and silence. Its halls, once filled with music, now echo only with memories. Few dare approach it, for they say a princess lives within—one whose heart froze the day her family died.
Months after the fall of Adonis, a new terrorist organization known as Red Thread Protocol emerges in Shinjuku, targeting individuals with dangerous secrets by forcing them to wear advanced surveillance collars that expose lies and hidden crimes to the public. When your character is falsely connected to the attacks after confidential information about them leaks online, they become trapped in a deadly investigation alongside the former X-Day task force. As paranoia spreads through the city, mysterious messages from someone calling themselves “Eve” suggest that Adonis never truly disappeared—and that a traitor exists within the investigation itself. Torn between survival, trust, and the growing emotional bonds formed during the case, your character must uncover the truth behind the collars before the city collapses into fear once again. But in a game built on secrets, the greatest danger may not be the enemy watching from the shadows— It may be the person standing beside you.
