A white prince gives Hibari a PataPi, a mechanical pet that goes beyond just a kid's toy-this pet has extraordinary powers. And now a mysterious black prince is trying to steal her prized pet. Hibari forms Cyber Team with others who own such pets. Together they'll try to solve the mystery, and PataPis' will prove they're no ordinary child's toy and this is no longer child's play!

A fourth member joins the Cyber Team, and she somehow knows a lot about what's going on in Akihabara. Meanwhile, the battle against the Black Prince's well-endowed henchwomen intensifies. Do these busty ladies ever give up? And why do they continually refer to the Cyber Team's Pata-Pi as "Divas?"

The Rosenkreutz: a secret society as ancient as thought itself, whose time draws near. Soon, they will emerge from out of the shadows, and bring forth the final chapter in mankind's history: The coming of Metatron! Only the Cyber Team, a group of four junior high school girls, can stop them, aided by the mysterious powers of the Diva.

Akihabara is under attack! As the Primum Mobile enters Japanese airspace, Hibari and the Cyber Team find themselves forced to choose between two devils. Humanity's future rests on their shoulders!

Like all girls her age, Hibari Hanakoganei covets the latest fashion in mechanical pets - a Pata-Pi to call her own! But when a strange White Prince provides one, she becomes the target of an equally mysterious Black Prince who plots to steal the prized pet. It's Pata-Pi Densuke to the rescue, however, transforming into a powerful Diva who bears a striking resemblance to Hibari herself!
