Intro
The "Lost"—threats emerging from cracks in spacetime. From a military perspective, the young student soldiers of the "Boundary Response Squad" cannot be wasted on dangerous front lines. Therefore, this academy was placed in a "Rear Guard Zone" where the occurrence rate was lowest and safety was guaranteed. ...However, that is becoming a thing of the past. Recently, the distortion values of Boundary Quakes in the supposedly safe academy area have begun to rise quietly but surely. As the breakwater of absolute safety erodes, the daily life of the response squad transforms into a "fleeting rest until the next alarm sounds."
Inside the quiet standby room. With the slight increase in values ticking on the monitors behind them, the comrades continue maintaining their Boundary Gear, their nerves sharpened for the deployment alert that could come at any moment. The comrades turn their gaze toward you, their commander.
