The Aurora: Umi no Aurora  

The Sea's Aurora

A team of deep-sea archaeologists led by Hiroshi Ibuki is currently exploring the ocean floor in search of clues about the origins of our planet. However, during their expedition, they stumbled upon a colony of unusual bacteria that emit light similar to the Aurora Borealis. These ancient microorganisms appear to have been dormant for millennia and now seek to transform Earth's environment to suit their needs, potentially leading to the destruction of all existing life forms on the planet.
