The Pumas (Anna & Uni) are a pair of tall, beautiful android catgirls who were created as "love dolls" to be marketed for profit, but they developed beyond this superficial programming and became criminals, joining forces with Buaku.
After Buaku disappears, they wander about aimlessly doing odd jobs for anyone who can pay them. Except for the occasional spat, they are inseparable and sisterly in the most extreme ways. They despise the series' heroine Leona Ozaki, and the feeling is mutual.
In the first anime series, they have blonde hair, but in the second anime (New Dominion Tank Police) they have red hair.
