SuperHigh

The series is set 150 years after humanity lost half of the planet due to a mysterious black fog. To contain the black fog, 3,000-meter-tall (about 10,000-feet-tall) walls were erected to split the world, and the half of the human population that survived now live in cities called arks. Shidou Enishi, one of the few Japanese survivors, runs a detective agency on the ninth ark. While pursuing a male suspect in a burglary, he learns of a massive conspiracy, one that may be tied to the Rivigarudo syndrome that is mutating its victims into something inhuman.

Yuu and Saya are two of the top Cosmic Hunters in the galaxy, and Yuu is enjoying a bit of fame after his most recent adventure. The two are on a date when they are interrupted by a distress signal from their "ally", the feline pervert Nyan. In the meantime, the space pirate Belga begins attacking space freighters in an attempt to lure out Yuu, so she can take him to bed with her. Of course, when he spurns her, she decides that if she can't have him, then no one can.
