Chousoku Henkei Gyrozetter or Chō Soku Henkei Gyrozetter (literally Hyper Speed Transformation Gyrozetter) is a multimedia franchise created by Square Enix, spanning a transforming Japanese arcade game, a manga series written by Ryutaro Ichmura and illustrated by Teruaki Mizuno, and an anime series by A-1 Pictures on the Fall 2012 Anime lineup.
In 21st-century Japan, vehicles known as “A.I. cars” are equipped with artificial intelligence which anyone can drive on the road safely. With this revolutionary technology, a special school, Arcadia Academy, was established in New Yokohama City in 2012 to teach children to drive these A.I. cars. One day, Kakeru Todoroki, a student of Arcadia Academy, is summoned by the school principal and given an A.I. car called Raibird, which turns out to be a transforming robot known as Gyrozetter. Together with other chosen drivers, he must use the Gyrozetter to stop an evil organization, Xenon, from world domination.
