The second installment of the Virtual Trilogy, blending anime with live-action footage. Virtual Station is a laboratory dedicated to collecting and researching DNA. By combining ancient DNA elements, the facility has virtually reconstructed the ancient world. Yui serves as one of the Gene Divers, entering this virtual ancient world to gather DNA from animals that are extinct in reality. However, an incident occurs. Yui attempts to exit the virtual world during a maintenance cycle, but instead of returning to reality, she is transferred to a new virtual present. In this new world, generated by the now uncontrollable system, an intelligent species evolved from rodents, known as puglaistig, exists. They view the existence of humankind as a serious threat and attempt to halt human evolution by any means necessary.
