The Kazei Five Worldbook is designed to allow a Game Master to create and run a Hero System 4th Edition campaign using elements common to many near-future cyberpunk anime. In recent years the availability of Japanese animation (i.e. anime) and comics (i.e. manga) has reached an all-time high. Videotapes of many popular shows are available for either sale or rent at most video stores, while several comics publishers offer translated editions of a variety of titles. Often the stories presented are quite different from what many people might expect, and contain genre conventions radically different from American cartoons or comic books. This book is an attempt to present one aspect of the anime and manga field, that of the near future anime-cyberpunk genre. As with the original source material, the world presented here is a dark one, and presents its subject matter in a serious tone. Although this specific field may not be for everyone, elements of this genre can be adapted for use in many other games.
