Geobreeders follows the adventures of the Kagura Total Security agency who are engaged in a battle with 'ghosts' who are electronic apparitions or phantom cats that can control any computer system. The teams female members are the president of the agency: small red-haired Yuka - somewhat of a merc; computer-wiz Takami who has serious problems dealing with stress; 'Crimson Shooting Star' with her affinity to big guns; the shapely, brass knuckle-toting accountant Eiko; and Yu, the chain-smoking driver with tendency to fall asleep often. Finally there is the phantom cat adopted by Mr. Taba - Maya the cat-girl. The very put-upon Mr. Taba is the token male of the group, and much of the humor comes at his expense - he takes all the worst jobs, and usually gets no credit. They are up against a phantom cast who are able to pass through material barriers and are impervious to many weapons, the feline fiends are plotting 'the annihilation of Japan' through a takeover of the national communications system.
