Norio, an ordinary high school student discovers his Zoomanity and deals with the advances of many male Zoomans who want him to have their babies.

The story of a band of spotty, noisy, working-class kids with “no future,” who shook the boring, corrupt Establishment to its core, threatened to bring down the government and changed music and culture forever.
