Hibari has just started middle school and like most of her classmates, she wants this years hottest toy, a Pata-pi.      She is not very good in her studies, nor is she smart or good in sports. She is, however, a very friendly and thoughtful person. Her crush was on a &quot;prince&quot; that often appeared in her dreams (the prince is the one who gave her Densuke, her pata-pi). Hibari&#039;s father works in the robot industry and her mother is a computer programmer. 

A "patapi" is a cute mechanical creature which is like a cyber pet. It can eat, sleep, play, and even help out its owners with some stuff. When Hibari Hanakoganei receives a patapi from a prince in her dreams, she is thrilled and names it "Densuke". When mysterious forces try to steal Densuke, Hibari discovers that Densuke is not just an ordinary patapi. Densuke has magical powers that allows it to transform into a powerful cyber-fighter who looks like Hibari. Hibari's friends also receive similar patapis, and together they form the Cyber Team in Akihabara.
