According to OP:
This game has a unique element called the "Popularity Effect."
When activated, various effects are triggered depending on each character's abilities.
Reimu:The number of Graze increases dramatically, increasing speed and time.
Marisa:Magic = Shooting attribute attacks deal increased damage and some techniques gain super armor.

This game not only has a mode where you play against the CPU, but also a story mode.
The story is based on 東方紅魔郷(the Embodiment of Scarlet Devil) of 幻想万華鏡(Gensou Mangekyou).
