"KiKi KaiKai (奇々怪界 lit. "Mysterious Ghost World") is a multi-directional shooter developed and published by Taito Corporation originally for Japanese arcades in 1986. Since then, the game has received a number of console and home computer ports in and outside of Japan, both as a stand-alone title and as part of compilations. The game originally saw a limited release in North American and European arcades as Knight Boy, a bootleg copy of the original Japanese version not officially licensed by Taito. In the English-speaking world, it is usually recognized as the forerunner to the Pocky & Rocky series.
Set in Feudal Japan, the player must assume the role of a Shinto shrine maiden named "Sayo-chan" who must use her o-fuda scrolls and ohari Gohei wand to defeat a number of renegade spirits and monsters from Japanese mythology. The game is noteworthy for using a traditional fantasy setting in a genre otherwise filled with science fiction motifs."
