Geobreeders (1998, also known as File X: Get Back the Kitty) and Geobreeders: Breakthrough (2000, also known as File XX: Breakthrough) are two OVA series based on Akihiro Ito's on-going manga of the same name. The story depicts members of Kagura Total Security as they fight against the Phantom Cats. Kagura's main business rival is the Hound, a secret government paramilitary organization under the control of the Ministry of Health and Welfare (since pest and animal control are part of the Ministry's mandates).
Phantom Cats are mystical beings capable of taking both human and feline forms as well as manipulating all form of electronic signals. This ability makes the cats master of information manipulation. Physical attack against the cats in human form will not permanently harm them as the cats have the ability to regenerate in human form. The Hound's equipped with special EM field generators that, when deployed, can neutralized Phantom Cats' abilities such as regeneration or escape through telephone lines. In order to eradicate them, Cats needs to be "sealed" using specially designed talisman or other devices.
The OVA storylines are considered canon and are incorporated into the main manga story.
