It was late in the night, and the whole shelter was fast asleep. Only three members of the defense team couldn't reunite with their beds, as they sat in the watchtowers by the gates, staring on the desolate streets below with their bleary eyes.
Deep in the campus, far away from their sight, a black-clad man crept alongside the wall of the school building, moving almost soundlessly. He was wearing a hood, and his face was wrapped with a thin scarf, as if trying to cover himself up as much as possible. His eyes frantically scanned the surroundings, and once he confirmed that no one was around, he raised himself up slightly, taking a peek into a shrouded in darkness classroom through a boarded-up window. He remained still for a moment, looking in and listening, before lowering himself back to the ground, and slowly moving forward to the next window.
