After 20 years of living in a terrible post-apocalyptic world, you find yourself in a miraculously undiscovered bunker, which… is filled with food and beautiful girls. It seems that your life is about to change, but… you can not even imagine how much.
This is a comic adventure with harem elements, where you can meet and improve relationships with four girls – the residents of the bunker. They are surprisingly very pleased with their new guest. Perhaps this is because they’ve never seen anyone from the “surface”? Or is there something else?
