Fantasy Maiden Wars: Scarlet

The first part of the Touhou fangame series: "Gensou Shoujou Taisen", based on Strategy RPG "Super Robot Wars" franchise.
This game retells Embodiment of Scarlet Devil --the sixth Touhou mainline game-- with the trademark red mist acting in the beginning as the catalyst for plot development; however, there are surprisingly many plot twists, character developments and cameo guest appearances from other games as well as portraying a prologue to Mountain of Faith's story. Altogether, the storyline is beautiful and much more rich in drama compared to the original Embodiment of Scarlet Devil.
