Once upon a time, Masamune Shirow could be relied on to churn out all sorts of interesting one-shot sci-fi stories. Most of them have been overshadowed by the massive success of Ghost in the Shell, and that's unfortunate. They weren't always masterpieces of transhumanism, but they were interesting in their own right.
DOMINION, by Masamune Shirow. First published in 1986 and first published in North America in 2000.
PLOT:
In the future, the skies are brimming with dangerous bacteria. Humanity has done everything to protect itself from the air, be it the strange pod-like beings they live in or the filter masks they wear outside. It's not enough to protect the people from everyday criminals like the thief Buaku and his catgirl henchwomen Annapuma and Unipuma. The only force capable of stopping them is the Tank Police, a hardscrabble group of cops dedicated to stopping crime (if not so much toward stopping collateral damage or pleasing their superiors).
