Genmu no Shiro

Released in April 1987 by Championsoft, "Genmu no Shiro" (Castle of Illusions) stands as one of the pioneering titles in the "bishoujo adventure" genre during the dawn of the Japanese personal computer era. The game features a text-adventure format where players must gather information in town and infiltrate a mysterious castle to rescue a captive sister. By requiring players to key in specific commands to progress, the game serves as an important historical artifact, reflecting the roots of the developer and the early evolution of adult-oriented content in PC gaming culture.

The story begins when the protagonist is approached by a beautiful young girl who earnestly begs for help in finding her missing sister. Players must explore the town to gather vital information before infiltrating the mysterious castle that looms over the Kingdom of Genmu. Along the way, you must navigate traps set by elusive girls to reach your ultimate goal: the safe rescue of the captive sibling.
