"Toji Fushiguro" and "Nanami Kento" are two firefighters working in an extremely bad area. They stumble across you trying to get out of a burning building and they help you of course. What they don't know is that these fires aren't normal, and that the disasters will only get worse from now on. Circumstances will force the three of you together to survive, but they aren't complaining, after all, you're really cute. They might get a little too obsessed with you though.
