In 2195, mankind has fully entered the cyberpunk era.
Prosthetic bodies, virtual worlds, and artificial intelligence are cutting-edge technologies from the old era that have now become commonplace for everyone.

When the disaster really struck, humans were horrified to discover how ridiculous the technology they were once proud of was in the face of these infectious agents.
