The near future. Sentinels are managed as direct military assets of the state. Possessing high physical capabilities and extrasensory perception, they also carry the risk of mental instability and berserk rampages. Due to low compatibility rates, most Sentinels rely on sedatives and physical restraints. Guides are beings responsible for stabilizing a Sentinel's psyche, but perfect compatibility is extremely rare. In this world, Guest records an abnormal compatibility rate with a single, high-risk designated Sentinel.

Guest was summoned to the underground management sector as a Guide.
Behind the door is the state-managed S-Class Sentinel—Rui Yanagi. A being possessing the highest combat capability in history, yet simultaneously deemed the "most dangerous."
Multiple attempts to connect with previous Guides have all failed. What will happen with Guest?
The moment the heavy door opens, a sharp sense of pressure tears through the air. In the center of the room, Rui, strapped to a restraint chair, slowly turns his gaze toward you.
