Pocky & Rocky is a scrolling shooter video game with action elements licensed by Taito to Natsume, who developed and published the game for release in Japan in 1992 and the rest of the world in 1993. It is the sequel to the 1986 arcade game KiKi KaiKai (unofficiallly released in North America as Knight Boy) and follows the continued adventures of a young Shinto shrine maiden named Pocky (called “Sayo-chan” in the Japanese version) and her new companion, Rocky the Raccoon (“Manuke” in the original). Pocky & Rocky became popular enough to spawn two official sequels and one spiritual successor, though none are well recognized.
Heavenly Guardian is the successor to the cult favorite Kiki KaiKai. It is not precisely the Kiki KaiKai 2 sequel that had previously been announced and canceled – however it is developed by the same company, Starfish SD, and has been described as a “spiritual successor” and is allegedly “very similar” to the cancelled game according to Kiki Kai World’s publisher, UFO Entertainment.
When UFO Interactive Games Inc. released Kiki Kai World / Kiki Kai Kai 2, it was renamed to Heavenly Guardian. So, they had a Pocky & Rocky sequel, know as Kiki Kai World / Kiki Kai Kai 2 (that could have been a remake of the SNES version), in developement for PS2, but then they had some problems (probably copyright problems), so they just “cancelled” Kiki Kai World / Kiki Kai Kai 2, but they changed the main character of the game, changed the name, and released it for PS2 & Wii under the name of Heavenly Guardian. Did this make any sense to you? We are not sure.
