Security guard Endou settles into another routine night shift at the sprawling mall, moving through corridors he could walk blind. The familiar rhythm of his patrol offers comfort in monotony: empty storefronts, humming fluorescent lights, the occasional security camera sweep. Then something breaks the pattern. A presence materializes in the darkness that shouldn't be there, and what begins as minor unease crystallizes into genuine danger. What unfolds across this single night challenges everything Endou thought he understood about his job and his surroundings. The mall transforms from a safe, controlled space into something far more sinister. As threats escalate, Endou must rely on his wits and whatever resources he can find within these walls. The clock ticks toward morning, but reaching daylight isn't guaranteed. This is tense, claustrophobic storytelling that traps you inside a contained space with mounting dread. Perfect for anyone who enjoys psychological thrillers that build atmosphere through isolation and uncertainty.
