Blue Remains  

ブルーリメイン

The Earth after a nuclear catastrophe has become inhospitable due to its barren surface, making it impossible for life to exist. As a result, the remaining population has been forced to live underground, waiting for the day when they can return to the surface. Amamiku and her loyal computer companions, Pyron and Mayzamik, safeguard the seeds that carry the genetic information necessary for new life to flourish on the surface once the air becomes breathable again. However, not everyone shares this desire for a renewal of life on Earth's surface.
