In 2071, roughly fifty years after an accident with a hyperspace gateway made the Earth almost uninhabitable, humanity has colonized most of the rocky planets and moons of the Solar System.

The Cowboy Bebop Booster Display contains 24 booster packs of 10 cards each for The Universal Fighting System (UFS).
