Nehan: Kanzenban

The protagonist, "I", was kidnapped by a mysterious group while buying cigarettes and locked in a room. "Where am I...?" The room was filthy, with only a large hole with no bottom visible. "Let's get out of here quickly..." "I" left the room, but the building was abnormal. One after another, corpses were found with their belongings removed, non-human objects attacked "I", and a horrifying scene that seemed not to be of this world. "I" tried to escape from there, discovering the few remaining surviving friends.
