Geobreeders (ジオブリーダーズ, Jioburīdāzu) is a manga series by Akihiro Ito. Two anime OVAs (the three-part "Get Back the Kitty" and the four-part "Breakthrough") were also produced. The OAVs were distributed in Japan by Shōnen Gaho-sha and JVC and in North America by U.S. Manga Corps under a single title. The manga was partially translated by CPM Manga. A sidestory, illustrated by Isamu Imakake (running in Monthly OURsLITE from December 2000 to June 2001) was released as Geobreeders Atomic Attack (ジオブリーダーズアトミックアタック).
Ayagane City has a phantom cat (also called "bake neko" and "were-cat") problem. A young and overzealous group of entrepreneurs called Kagura Total Security can be hired to combat this problem for the right price when Hound, the official government arm, isn't enough. However, there are plots and subplots floating beneath the surface, both involving Kagura, and the were-cats, led by Kuro-Neko, themselves. Both the manga and the OVAs are heavily action-driven, with gunfights appearing every few chapters.
