The Dirty Pair, Biohazards [first edition]

The Dirty Pair face their greatest challenge yet when Kei confronts the awesome horror of...her employee evaluation! It looks simple: simulations are generated by the Central Computer to test her responses, but when a mysterious malfunction traps Kei in virtual reality, Yuri must enter the sim to save her from a series of increasingly night-marish scenarios. From outer space to the ocean depths to the infinity of cyberspace, can Kei and Yuri survive the simulated -- but still lethal -- terrors of the apocalyptic "Nanoclysm"?
