The Lovely Angels are dispatched to the planet of Ookbar in search of a missing girl. Kei and Yuri have traced young Missinie to the forest of Nolandia, but their investigations have stalled thanks to the less than helpful Chief of Security. But Kei and Yuri never let a little bureaucracy stand in their way. It's the unicorns and UFOs, not to mention the rampaging killer robot, that are going to be the problem as the Dirty Pair tackle their toughest case yet.

The 3WA's Central Computer gave the Lovely Angels two cases at once! Kei and Yuri must investigate a space liner explosion and, simultaneously, find a missing scientist. It all seems easy enough, but this is actually the Angels' most dangerous mission yet – and if they're not careful, it'll be their last.

Agerna is a planet rich in Vizorium, the one mineral necessary to space travel. When a series of mysterious attacks on mining operations has world leaders pointing fingers and pinning blame, 3WA naturally send in their top agents to investigate. But are the Lovely Angels up to the task of stopping a mad scientist bent on taking a long dormant alien race to its final evolutionary form? Throw in a thief after a bottle of WWII-vintage wine and it's a safe bet that nobody's safe. It's more chaos, more mayhem, and even more destruction than ever before as the Dirty Pair take on their wildest case yet!

Kei and Yuri investigate a counterfeiter with a large amount of electronic defense gadgets/robots and then try to stop a megalomaniac from holding Chief Gooley and Eleanor City hostage.
