Touhou Kaikidan (東方怪綺談) ~ Mystic Square is the fifth and final PC-98 game of the Touhou Project franchise. It's commonly seen as the most polished and highly rated of the PC-98 era games, yet so little is actually known behind the scenes of how the game works.
This wiki is (hopefully) here as a database to explain more in depth about how this game works: from characters, story, mechanics; to the history behind the game itself: from the past development to the people of the present breaking the limits of Mystic Square.
