Overview

KID, an abbreviation of Kindle Imagine Develop, was a Japanese video-game company that operated from 1988 until its bankruptcy in 2006. The company became particularly associated with porting, adapting, and developing bishōjo games and story-driven visual novels for consumer game platforms, although its catalogue was considerably broader during its early years. KID worked as a contract developer in the early 1990s and contributed to a range of action, sports, arcade, licensed, and family-oriented games. Early projects and development work included Burai Fighter, Low G Man: The Low Gravity Man, G.I. Joe, Isolated Warrior, Recca, and other titles for platforms such as the Famicom, Super Famicom, Game Boy, and arcade hardware. A significant change in KID’s business occurred in 1997, when it began porting PC games to consoles. This placed the company within Japan’s growing market for consumer adaptations of PC adventure and romance games and helped establish the production practices that later defined its better-known visual-novel catalogue. In 1999, KID released Memories Off for the original PlayStation. The title developed into the company’s first major long-running original series and became a central part of its identity. KID also released Pepsiman in 1999, a game based on the Japanese soft-drink mascot. Although it was not initially a major commercial success, it later acquired a cult following among players interested in unusual licensed and character-driven games. KID expanded its reputation in 2000 with Never 7: The End of Infinity, the first released entry in the Infinity series. The series combined branching narrative structures, romance-oriented character routes, mystery, and speculative or psychological themes. Subsequent entries included Ever 17: The Out of Infinity, Remember 11: The Age of Infinity, and 12Riven: The Psi-Climinal of Integral. The company continued to develop and publish visual novels while also producing or adapting other works, including My Merry May, Monochrome, Close to, We Are*, Separate Hearts, and titles based on existing properties or previously released PC games. KID’s output was not limited to visual novels. Its catalogue included sports and board-game software, platform and action games, racing titles, shooters, and licensed works. It developed or published projects for the PlayStation, PlayStation 2, PSP, Dreamcast, Sega Saturn, WonderSwan, Game Boy, Super Famicom, and other systems. The company also created the unconventional PlayStation title Board Game Top Shop and remained active in adaptations and consumer-platform conversions. In 2005, KID served as a sponsor of the Japanese television drama Densha Otoko, linking the company to a high-profile contemporary media property outside the game market. KID declared bankruptcy in 2006. Its closure did not end the commercial life of its intellectual property. In February 2007, CyberFront Corporation was reported to have acquired KID’s rights and to have continued unfinished projects. CyberFront later closed in December 2013. Kaga Create subsequently acquired CyberFront and held rights connected with KID’s works; after Kaga Create itself ceased operations, 5pb. acquired CyberFront’s assets, including KID-related properties. Many of KID’s best-known works therefore continued through successor companies, re-releases, ports, and related publishing arrangements, with Mages later identified as the current owner of most of the former KID intellectual property. KID is consequently remembered less as an active company than as an influential catalogue and brand within Japan’s visual-novel and bishōjo-game history.

History

KID was founded in Japan in 1988 and initially operated primarily as a contract developer. During the early 1990s, its work covered a broad selection of genres and platforms rather than focusing exclusively on visual novels. The company was involved with titles such as Burai Fighter, Low G Man: The Low Gravity Man, G.I. Joe, Isolated Warrior, Recca, and other games for Nintendo systems, handheld hardware, and arcade platforms. This period gave KID experience in technical development, licensed properties, and conversion work. In 1997, KID began porting PC games to consoles. The move was strategically important because Japanese PC adventure and romance games could reach new audiences through consumer systems. KID developed a substantial body of adaptation and publishing expertise during this period, later applying it to original narrative projects and to games originating with other PC developers. The company’s major breakthrough came in 1999 with Memories Off, an original PlayStation visual novel. The game established a continuing series and helped define KID’s public identity as a producer of romance-oriented, character-focused adventure games. That same year, KID released Pepsiman, a licensed title based on the Japanese beverage mascot. The game had limited initial success but later became recognized as a distinctive cult title. KID’s other defining property began in 2000 with Never 7: The End of Infinity. It launched the Infinity series, which developed a reputation for combining relationship routes and visual-novel conventions with mystery, psychological tension, speculative concepts, and complex narrative structures. Later works included Ever 17: The Out of Infinity, Remember 11: The Age of Infinity, and 12Riven: The Psi-Climinal of Integral. KID also produced or adapted numerous other visual novels and adventure games, including My Merry May, Monochrome, Close to, We Are*, Separate Hearts, and consumer versions of games originally created by other studios. Despite this specialization, KID maintained a diverse catalogue. Its work included board games, sports games, racing software, action titles, shooters, platform games, and adaptations of anime, manga, television, and commercial characters. The company released games across the PlayStation family, Dreamcast, Sega Saturn, Game Boy, Super Famicom, PSP, WonderSwan, arcade systems, and other platforms. In 2005, KID sponsored the Japanese television drama Densha Otoko, demonstrating an effort to associate the company with a broader media property and contemporary popular culture. KID declared bankruptcy in 2006. The company’s closure was followed by a series of asset and rights transfers rather than the disappearance of its catalogue. CyberFront acquired KID’s intellectual property in 2007 and continued unfinished projects, but CyberFront itself closed in 2013. Kaga Create then acquired CyberFront and held rights connected with KID’s works. After Kaga Create shut down, 5pb. acquired CyberFront’s assets, including KID-related properties. The former KID catalogue subsequently remained relevant through successor-company releases and ownership arrangements, and most of the intellectual property is currently associated with Mages. KID therefore occupies an important historical position as a Japanese game company whose early contract work evolved into a recognizable visual-novel publishing and development identity, even though the original company no longer exists.
