Touhou Koumakyou

Touhou Koumakyou, Japanese title 東方降魔叫, is a Touhou Project doujin game for Windows by the Japanese circle GEN, credited to the author Tetsuko and dated 16 August 2014, sold as a download title. Although it romanises the same way, its title is written with different characters from ZUN's 東方紅魔郷 and it is a separate work by a different circle. In its story Marisa Kirisame visits the Scarlet Devil Mansion and finds a grimoire lying in a corridor, which is in fact a trap Remilia prepared specifically for her: the floor gives way and Marisa falls with the book into the mansion's basement. The circle's own site lists a September 2014 patch that added a LUNATIC difficulty and boss spell cards exclusive to HARD and LUNATIC.
