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!
With astonishing battle agility, Densuke proves to be no ordinary child's toy! But Hibari is not the only one with a Pata-Pi of extraordinary powers, and despite an unlikely friendship, she joins forces with others to form the Cyber Team! Together will they solve the riddle of the Black Prince - or will his flock of nefarious cohorts put an end to the dynamic divas of Akihabara?
